Product Description
IS40ySSCAH2A is a resistance temperature device input module for General Electric. This module is part of the General Electric Mark VIe Speedtronic system, which was one of the last available Speedtronic systems. The Speedtronic series was created by General Electric in the 1960s to manage industrial gas and steam turbines, including popular versions such as Mark I, Mark II, Mark IV, and Mark VI.
IS40ySSCAH2A is an I/O package designed for use with terminal boards. When used in conjunction with specific terminal boards such as IS200TRTDH2D, IS200SRTDH1A, or IS200SRTDH2A, it is approved for use in hazardous locations. This device has its own power supply.
Only resistive simple devices (such as RTDs) should be connected to the RTD input on IS220PRTD1A. The cables used for these connections should have appropriate insulation as specified in local electrical regulations.
The front panel of IS40ySSCAH2A includes LED indicators for the two Ethernet ports of the I/O unit, as well as power and ATTN LED indicators. The port is located on the side of the device.
Before adding any packaging materials, the weight of the device is approximately 4.40 pounds. The dimensions are 34 x 18 x 10 centimeters. This device is CE marked and complies with UL standards.
Function Description
IS40ySSCAH2A is a resistance temperature device input module manufactured and designed by General Electric, belonging to the Mark VIe series used in distributed control systems. The resistance temperature device (RTD) input (PRTD) package is electrically connected to the RTD input terminal board and one or more I/O Ethernet networks. The package includes a dedicated acquisition board for thermocouple input function, as well as a processor board shared by all Mark VIe distributed I/O packages. The I/O package can support up to eight RTD inputs, while the TRTD terminal board can support up to sixteen RTD inputs. Input using a DC-37-pin connector directly connected to the terminal board connector of the package, as well as a three pin power input. There are two RJ45 Ethernet connectors for output. The indicator light LED is used to display visual diagnosis.

IS40ySSCAH2A compatibility
The RTD input terminal boards TRTDH1D, H2D, and SRTD are all compatible with PRTDH1A, but the DRTD boards installed on DIN rails are not compatible. The following table provides compatibility information.
One I/O packet and one or two network connections are used in a simplex manner.
Dual uses two I/O packets with one or two network connections.
TMR uses three I/O packets, each with a network connection.
The TRD input circuit is electrically isolated by PRTD. This requires modifications to the transient protection of the terminal boards of TRTDH1D and TRTDH2D. The H1D version of the board provides filtering that is compatible with the PRTD standard scanning rate. When selecting the fast scanning rate of PRTD, the H2D version of the terminal board provides less filtering to achieve appropriate performance. Although there will be no physical damage, if PRTD is installed on an earlier version of the TRTD board, incompatibility will be detected.
IS40ySSCAH2A installation
Firmly install the required terminal board.
Connect one or two PRTDs directly to the connection on the terminal board (for simplex control of eight or 16 RTDs).
Use the threaded plug next to the Ethernet port to mechanically secure the battery pack. Connect the plugin to a mounting bracket specific to the type of terminal board. It is important to position the bracket in a position where the DC-37 pin connector between the terminal board and battery pack will not be subjected to a right angle force. Within the service life of the product, only one adjustment is required.
According to the system configuration, connect one or two wires to ensure optimal operation on either port. When using dual connections, ENET1 is usually linked to the network connected to the R controller.
Connect the connector on the side of the component to power the battery. The I/O component includes a built-in soft start function that can limit current surges when powered on, so there is no need to unplug the cable before connecting.
To customize I/O packages as needed, use the ToolboxST * application.
Processor board operation
Connect the I/O package or module function specific acquisition board to the processor board. When the input power is turned on, the soft start circuit will increase the available voltage on the processor board. The processor is reset and turned off, and the local power is turned on in order. After completing the self-test program, the processor loads application code from flash memory specific to the I/O package or module type. To verify whether the application code, acquisition board, and terminal board are correctly matched, the application code will read the board ID information. When the match is good, the processor will attempt to initiate an Ethernet connection by requesting a network address.
The address request uses both the industry standard Dynamic Host Configuration Protocol (DHCP) and the unique identifier of the terminal board. After the Ethernet is started, the CPU runs the application program, programs the onboard logic, and allows the collection board to start working.
The processor application code contains the entire circuit required to enable I/O packets to run through one or two Ethernet inputs. When using two Ethernet inputs, both network paths are always active. I/O package or module operations will not be blocked due to any network failure, and a functioning network connection will display a fault. Compared to traditional hot backup systems where the second port is only used in the event of a primary port failure, this configuration has higher fault tolerance. The Ethernet port of the processor will automatically negotiate between half duplex and full duplex operations at speeds between 10 MB/s and 100 MB/s.
The processor board is a common component of all Mark VIe Ethernet I/O packages or modules. It includes the following content:
A fast processor with RAM and flash memory is the top priority.
Two completely independent 10/100 Ethernet port plugs
Hardware reset and watchdog timer circuit
Internal temperature sensor
LED indicating status
Ability to read IDs and electronic recognition on other boards
Input power connector with current limiter and gentle start
Local power supply, including monitoring and sorting
IS40ySSCAH2A diagnosis
Power on self-test checks the hardware on the CPU board, Ethernet ports, RAM, and flash memory.
Continuously check if the internal power supply is functioning properly
Verify hardware settings match by comparing electronic ID data from CPU, acquisition board, and terminal board, and then check if the application code loaded from flash memory is suitable for hardware settings.
The hardware limitation check for each type of RTD is based on predetermined (non configurable) high and low levels located near the edge of the operating range. Once this limit is reached, the input will no longer be checked, but logic signals will be set.
If the hardware limit of any one of the eight inputs is reached, a composite diagnostic alarm L3DIAG PRTD will be generated that involves the entire circuit board. The toolbox provides information about each diagnosis. It is possible to lock a single diagnostic signal and reset it using the RESET DIA signal.
Perform system limit testing on each RTD input using customizable high and low levels. These restrictions can be adjusted to enable/disable and lock/unlock, which can be used to trigger alarms. The signal exceeding the limit is reset through RESET SYS.
The toolbox provides detailed information for each diagnosis. The diagnostic signal can be individually latched. If the diagnostic signal returns to normal, use the RESET DIA signal to reset.
