GE IS220PTCCH1B Mark VIe Thermocouple Input Module I/O Pack

Product Overview

The General Electric IS220PTCCH1B is a specialized Thermocouple Input I/O Pack manufactured for the GE Speedtronic Mark VIe Control System series. Purpose-built for critical gas turbine automation and industrial process control, this module provides accurate signal acquisition and conditioning for up to 12 combustion-optimized thermocouple inputs alongside 1 cold junction reference input.

Operating on a 28 V DC power supply at a low power consumption of 0.16 Amps, the IS220PTCCH1B supports versatile control architectures including Simplex, Duplex, and Triple Modular Redundant (TMR) configurations. Weighing approximately 0.45 kg (0.99 lbs) with compact, DIN-rail or terminal-mounting form factor, it interface-connects directly to terminal blocks to digitize temperature measurements across long-distance industrial field wiring.

Core Technical Advantages

• Broad Thermocouple Compatibility: Accommodates standard E, J, K, S, and T thermocouple types (grounded or ungrounded) as well as direct millivolt inputs spanning -8 mV to +45 mV.
• Combustion-Optimized Performance: Features 12 high-accuracy input channels specifically tailored to monitor turbine exhaust and combustion chamber thermal dynamics.
• Flexible Control Redundancy: Fully configurable for Simplex, Duplex, or TMR system topologies to maximize plant availability and fault tolerance.
• Long-Distance Field Wiring: Supports cable distances up to 984 feet (300 meters) from the turbine I/O panel with maximum allowed line resistance up to 450 ohms.

Technical Specifications

Installation & Gap Calibration Guide

• Terminal Mount & Network Link: Mount the IS220PTCCH1B onto the corresponding terminal board D-sub connector and secure the dual IONet Ethernet connections for communication.
• Field Wiring Verification: Connect thermocouples (types E, J, K, S, T) ensuring loop cable resistance remains below 450 ohms across runs up to 984 feet.
• System Configuration: Configure channel types and cold junction parameters within ToolboxST software to align with Simplex or TMR system requirements.
