Product Description
Characterized as a Discrete Output Pack the IS220PDOAH1A model was designed with interfacing up to two I/O Ethernet networks and other discrete output terminal boards in mind. One special function of this model is that it can control up to twelve relays as well as accept feedback signals from other terminal boards. The typical relays that can be used with this model are solid-state relays and electromagnetic relays. The solid-state relays are used with the TRLYH1B, C, D, and F terminals whereas the electromagnetic relays are used with the TRLYH1E boards. The inputs that will be received on this pack with come through the double RJ45 Ethernet connectors as well as a three-pin power input.
There is a processor board embedded in the IS220PDOAH1A pack. There are multiple processors which include but are not limited to status-indicating LEDs, local power supplies for monitoring and sequencing, a high-speed processor which includes flash and RAM memory, and even more. All of the information on processors can be found in the GEH-721G Mark VIe Control System Guide, information can be found on pages two hundred and twenty-three to two hundred and thirty.
There is an output enable feature that is used with the IS220PDOAH1A pack. During the application in which power is given to the pack, all of the outputs will be disabled until a number of internal self-tests have been fulfilled. The enable function can provide paths that are independent of the command which will ensure that the relays are staying dropped out during the initialization and power-up of the pack.
IS220PDOAH1A is a Discrete Output Pack and is part of the GE Speedtronic Mark VIe gas turbine control system. It connects one or two I/O Ethernet networks to a discrete output terminal board via an electrical interface. The pack includes a processor board shared by all Mark VIe distributed I/O packs as well as an acquisition board dedicated to the discrete output function.
IS220PDOAH1A Functional Description
The pack can control up to 12 relays and accepts feedback from the terminal board. There are magnetic relays (TRLYH1B, C, D, and F terminal boards) and solid-state relays (TRLYH1E boards) available. The pack is powered by three-pin power input and two RJ45 Ethernet connectors. Output is via a DC-37 pin connector that is directly connected to the associated terminal board connector. Indicator LEDs provide visual diagnostics, and an infrared port allows for local diagnostic serial communications.
Compatibility
It works with six different types of discrete (relay) output terminal boards, including TRLY and SRLY boards, but not DIN-rail mounted DRLY boards. The number of I/O packs used in a signal path is referred to as the control mode:
Simplex employs a single I/O pack and one or two network connections.
Dual employs two I/O packs with one or two network interfaces.
TMR employs three I/O packs, each with one network connection.
IS220PDOAH1A Installation
Installing the PDOA pack:
Securely mount the terminal board of choice.
Insert one simplex PDOA I/O pack or three TMR PDOA I/O packs directly into the terminal board connectors.
Use the threaded studs next to the Ethernet ports to mechanically secure the packs. The studs fit into a terminal board-specific mounting bracket. The bracket should be positioned so that no right-angle force is applied to the DC37 connector between the pack and the terminal board. The adjustment should only be needed once during the product’s lifetime.
Depending on the system configuration, connect one or two Ethernet cables. The pack will work with either port. When using dual connections, it is common practice to connect ENET1 to the network associated with the R controller.
Connect the pack to power by plugging in the connector on the pack’s side. This connector does not need to be inserted with the power disconnected from the cable because the I/O pack has an inherent soft-start capability that controls current inrush on power application.
Configure the I/O pack as required.
IS220PDOAH1A Operation
Processor
The processor board is linked to an acquisition board that is dedicated to the I/O pack function. When input power is applied, the soft-start circuit increases the voltage available on the processor board. The local power supplies are turned on in sequence, and the processor reset is disabled. After completing self-test routines, the processor loads application code specific to the I/O pack type from flash memory.
The application code reads board ID information to ensure that the application code, acquisition board, and terminal board are all correctly matched. With a good match, the processor attempts to establish Ethernet communications, beginning with a network address request.
The address request employs the industry-standard dynamic host configuration protocol (DHCP) and the terminal board’s unique identification. Following Ethernet initialization, the processor programs the onboard logic executes the application, and allows the acquisition board to start up.
Relay Command Signals
The PDOA relay command signals are used as the first stage of signal conditioning and level shifting to connect terminal board outputs to control logic. Each output is an open collector transistor circuit with a current monitor that detects when the output is selected and connected to a load. When an output is picked up and connected to the terminal board, the status LEDs and monitor outputs illuminate. If the output is selected but no load is detected, the status LED will turn off and the monitor line will be false.
Output Enable
During power application, all outputs are disabled until a series of internal self-tests are completed. An enable line reflects the status of all required operating conditions. This function provides an independent path to ensure that relays remain dropped out during power-up and initialization.
IS220PDOAH1A Features
The number of relay channels in a single PDOA pack is 12 relays (different types depending on the terminal board)
15-pack inputs are monitored by a relay and a coil. The type of terminal board used, as determined by the ID chip, influences the selection of monitor feedbacks.
The I/O pack response time is approximately 6 ms from Ethernet command to output.

Reviews For IS220PDOAH1A
When using this model any/all of the visual diagnostics needed to determine the function of the PDOA pack will be located on the front of the device. If for any reason one of the LEDs does not work it will likely need to be replaced to ensure that everything is working properly.
