GE IS220PTCCH1A Thermocouple Input Module
Product Description:
The GE IS220PTCCH1A is a Thermocouple Input Module part of the Mark VIe Series, serving as an electrical interface between 1–2 I/O Ethernet networks and thermocouple input terminal boards in distributed control systems. It integrates a common Mark VIe processor board and a thermocouple-specific acquisition board, handling up to 12 thermocouple inputs per pack. In TMR configurations with TBTCH1B boards, three packs are used with three cold junctions but support 12 thermocouples. Communication occurs via dual RJ45 Ethernet ports, power via a three-pin connector, and outputs via a DC-37 pin connector to terminal boards. LEDs and an infrared port provide visual and serial diagnostics.
Key Features:
Thermocouple Support: Handles E, J, K, S, and T thermocouples and mV inputs, with up to 12 inputs per pack and scalability to 24 inputs with two packs.
Flexible Configurations: Compatible with simplex, duplex, and TMR setups, adapting to redundancy needs in critical systems.
Easy Installation: Plugs directly into terminal boards, secured via threaded studs to avoid connector stress; soft-start capability allows hot-plugging power without shutdown.
Robust Communication: Dual 10/100 Ethernet ports and infrared serial port for local diagnostics.
Performance & Diagnostics: High accuracy, 100 dB AC common-mode rejection, and self-tests for memory, hardware, and power supplies. Operates in -30°C to +65°C ambient conditions.
Processor Features: Includes a high-speed processor with RAM/flash, hardware watchdog, ambient sensor, electronic ID verification, and programmable logic supporting the acquisition board.
