The IS220PAICH1B I/O package is the second version of the PAIC analog I/O module, which can be used with terminal boards IS200STAIH1A, IS200STAIH2A, or IS200TBAIH1C. The minimum required power supply voltage for this model is 22.5 volts.
Product Description
The IS220PAICH1B model is produced by General Electric and is part of the analog input/output package of the Mark VI series. This model is the second version of the PAIC unit, and its minimum operating voltage is different from the previous version of the PAIC package. The minimum voltage for this specific device is 22 volts and a half direct current. The nominal power supply used in this model is 24 volts or 28 volts DC.
Although the IS220PAICH1B package is used in the Mark VI series, it can be used with some accessories (also known as terminal boards); The terminal boards used for this specific analog I/O package are all IS200 boards, including IS200TBAIH1C, IS200TAIH1A, and IS200TAIH2A. The IS200TBAIH1C model is a fence type junction box that requires a minimum wire size of 22 AWG for connection and use with the IS220PAICH1B package.
When using this model, a specific alarm will appear, one of which is marked as 82-83. This alarm is mainly aimed at the output, indicating that the suicide relay in the IS220PAICH1B package is not working. The possible causes of this alarm are usually a mismatch between the suicide relay command in the package and the relevant feedback, hardware failure, or relay failure on the acquisition board. The main method to solve this problem is to replace the I/O package itself.
The IS220PAICH1B package can be used in many different locations, including hazardous and non hazardous areas, and is certified as UL E207685 for non hazardous areas according to this model.
IS220PAICH2B is an analog I/O module developed by GE. This module serves as the electrical interface between one or two Ethernet I/O networks and input terminal boards. This package includes a processor board shared by all Mark VIe distributed I/O packages and a dedicated acquisition board for analog input functionality. This kit can handle up to 10 analog inputs, of which the first 8 can be set as 5 V or 10 V inputs or 0-20 mA current loop inputs.
IS220PAICH2B connector
The packaging includes the following connectors:
The DC-37-pin connector at the bottom of the I/O package is directly connected to the discrete input terminal board. 24 input signals, ID signals, relay coil power supply, and feedback multiplexed commands are all accommodated on the connector.
The main system interface is an RJ45 Ethernet connector labeled ENET1 on the side of the battery pack.
The redundant or auxiliary system interface is the second RJ45 Ethernet connector labeled ENET2 on the side of the battery pack.
The 3-pin power connector on the side of the batte
processor
All the logic required for I/O packets to operate through one or two Ethernet inputs is included in the processor application code. When using two Ethernet inputs, both network paths are always active. Any network failure will not interrupt the operation of I/O packets or modules, and the fault will be indicated by the working network connection. This configuration has higher fault tolerance than traditional hot backup systems, which only use the second port when the primary port fails. The Ethernet port of the processor can automatically negotiate between speeds of 10 MB/s and 100 MB/s, as well as between half duplex and full duplex operations.
energy management
The 28 V input circuit of the I/O package includes power management. The management function provides soft start to control current surges during power application. After being powered on, the circuit implements a fast current limiting function to prevent battery pack or terminal board faults from spreading back to the 28 V power supply system. When the power is turned on and working properly, the green PWR LED indicator will light up. When the current limiting function is activated, the PWR LED will remain off until the problem is resolved.
IS220PAICH2B installation
Firmly install the selected terminal board.
Insert the PAIC I/O package directly into the terminal board connector.
Use the screw next to the Ethernet port to mechanically secure the battery pack. These screws are installed on a dedicated mounting bracket for the terminal board. The placement of the bracket should ensure that the DC-37 pin connector between the battery pack and terminal board is not affected by right angle forces. Only one adjustment is required within the service life of the product.
According to the system configuration, connect one or two Ethernet cables. This package is applicable to any port. When using dual connections, the usual practice is to connect ENET1 to the network associated with the R controller.
Insert the connector on the side of the battery pack and connect the battery pack to the power source. Due to the inherent soft start function of the I/O pack, it can control current surges in power applications, so there is no need to disconnect the power supply before inserting the cable.https://www.weikunfadacai1.com/
Use the ToolboxST application to configure I/O packages as needed.
IS220PAICH2B diagnosis
The I/O package runs the following self diagnostic tests:
Power on self-test, including RAM, flash memory, Ethernet ports, and most processor board hardware; and Continuously monitor internal power supply to ensure normal operation.
Check the electronic ID information of the terminal board, acquisition board, and processor board to confirm hardware group matching, and then check if the application code loaded from flash memory is correct for the hardware group.
Perform hardware limit checks on each analog input based on the preset high and low levels near the end of the working range. When this limit is reached, a logic signal will be generated and the input will no longer be scanned. L3DIAG xxxx refers to the logical signal of the entire board.
Perform system limit checks on each input based on configurable high and low levels. These restrictions can be used to generate alerts, enable/disable devices, and serve as lock/unlock switches. RESET SYS clear out of bounds.
Each scan of the analog input hardware includes a precise reference voltage. Compare the measured values with the expected values to confirm the operation of the analog-to-digital converter circuit.
A small load resistor is used to detect the analog output current on the terminal board. The I/O package adjusts the signal and compares it with the instruction current to ensure that the analog-to-digital converter circuit is in good working condition.
Continuously check the consistency between the command status and feedback indication of the simulated output suicide relay. The ToolboxST application provides information about individual diagnostics. Each diagnostic signal can be latched and then reset using the RESET DIA signal when they become normal.
