GE IC693TCM302

Product Overview

The IC693TCM302 is a high‑performance 8‑channel temperature control module from GE Fanuc (Emerson Automation) for Series 90‑30 PLC systems, integrating 8 thermocouple inputs (J, K, L types) and 8 PWM relay outputs in a single slot. It supports closed‑loop PID control or open‑loop manual control per zone, with 12‑bit (0.2°C) resolution, ±1°C accuracy, and automatic cold junction compensation via 1 RTD channel or external reference. The module provides 18–30VDC relay outputs (100mA per channel), open thermocouple/reverse connection detection, and LED status indicators for quick diagnostics, fitting standard Series 90‑30 baseplates to control 8 independent temperature zones in industrial processes.

Functional Features

8 Independent Zones: Controls 8 separate temperature areas with dedicated input/output per zone.
PID/Manual Control: Closed‑loop PID (auto) or open‑loop manual mode selectable per channel.
High Precision: 12‑bit resolution (0.2°C) and ±1°C accuracy with automatic calibration.
Cold Junction Compensation: 1 RTD channel or external reference for accurate thermocouple readings.
PWM Relay Outputs: 0.1–60s period for precise heating/cooling cycle control.
Fault Detection: Open thermocouple, reverse connection, and out‑of‑tolerance temperature alerts.
LED Diagnostics: RUN, FAULT, SHORT, External Power, and per‑channel output indicators.
Single‑Slot Design: Fits any Series 90‑30 baseplate slot without extra space.
Overload Protection: 700mA typical threshold (≥2ms) prevents output damage.
±12V Common Mode: Rejects noise in industrial environments.

Application Scenarios

Process Heating/Cooling: Controls zones in plastic extrusion, heat treatment, and semiconductor fabrication.
Food & Beverage: Regulates ovens, pasteurizers, and fermentation tanks with 8 independent zones.
Packaging Machinery: Maintains seal bar temperatures for consistent packaging quality.
Environmental Chambers: Manages temperature in test/incubator chambers with PID precision.
Automotive Manufacturing: Controls paint curing, welding preheat, and battery testing zones.
Laboratory Equipment: Supports 8‑zone temperature profiling in material research setups.
HVAC Systems: Manages multi‑zone heating in industrial buildings with relay‑driven actuators.

Ordering & Compatibility

Standard model: IC693TCM302. Compatible with all Series 90‑30 baseplates, CPUs, and I/O modules. Requires 18–30VDC external power for outputs; backplane 5VDC (150mA) for logic. Pair with thermocouple extension wire and terminal blocks for field connections. No internal battery; use IC693ACC301 for RAM backup if needed.
