GE IS220PDIAH1A Mark VIe Contact Input Terminal Board

GE IS220PDIAH1A is a discrete contact input terminal board made by General Electric, which is part of the Mark VIe series used in GE's distributed turbine control systems.

Basic Information

• Part Number: IS220PDIAH1A.
• Manufacturer: General Electric.
• Product Type: Discrete contact input terminal board.
• Weight: 0.8 kg.
• Size: 15.9 cm high and 17.8 cm wide.

• Operating Temperature: -40 to +70 °C.

Function and Structure

• Interface Function: The PDIA I/O pack provides the electrical interface between one or two I/O Ethernet networks and a discrete input terminal board. It contains a processor board common to all Mark VIe distributed I/O packs and an acquisition board specific to the discrete input function.
• Input Capability: It can accept up to 24 contact inputs and terminal - board - specific feedback signals, supporting three different voltage levels. Connections for the isolated discrete input board with voltage sensing are available. System input to the pack is through dual RJ45 Ethernet connectors and a three - pin power input. Discrete signal input is through a DC - 37 pin connector that connects directly with the associated terminal board connector.

• Diagnostic Function: Visual diagnostics are provided through indicator LEDs, and local diagnostic serial communications are possible through an infrared port.

It is equipped with a high - speed processor with RAM and flash memory, and has two fully independent 10/100 Ethernet ports with connectors, a hardware watchdog timer and reset circuit, a local ambient temperature sensor, an infrared serial communications port, status - indication LEDs, electronic ID, and the ability to read IDs on other boards. It also has substantial programmable logic supporting the acquisition board, and an input power connector with soft - start/current limiter, as well as local power supplies, including sequencing and monitoring.
