GE IC660EBA103 – Thermocouple Input Block for Temperature Measurement

The GE IC660EBA103 acquires temperature signals directly from thermocouple sensors. This input block measures 185 mm in height and 90 mm in width. It has a depth of 55 mm, so it fits standard DIN rails easily. The unit weighs 0.68 kg, making installation secure and straightforward.

Input Channels and Thermocouple Types

This thermocouple block provides 4 isolated input channels for temperature sensors. The GE IC660EBA103 accepts types J, K, T, E, R, S, and B thermocouples. Each channel includes a dedicated cold junction compensation circuit. The block automatically linearizes the thermocouple signal for accurate readings. You can mix different thermocouple types across the four channels freely.

Measurement Accuracy and Resolution

The GE IC660EBA103 achieves an accuracy of ±1.0 degree Celsius across the full range. It provides a resolution of 0.1 degree Celsius for precise temperature monitoring. The module includes digital filtering to reject 60 Hz electrical noise. An open thermocouple detection circuit flags broken sensor wires. The input impedance exceeds 10 megohms for minimal signal loading.

Internal Architecture and Component Layout

The block contains two separate circuit boards inside its metal housing. One board handles signal conditioning, while the other manages Genius communication. The GE IC660EBA103 includes a dedicated microcontroller for cold junction compensation. A 20-pin removable terminal block accepts all thermocouple wiring. The module stores 150 µF of capacitance for power supply filtering.

Genius Network Interface and Power Requirements

A built-in Genius bus interface connects this block to the I/O network. The GE IC660EBA103 communicates at 153.6 kbit/s for fast data exchange. It draws 220 mA at 24V DC from an external supply. The module automatically reports its configuration to the bus controller. Rotary switches set the device address from 0 to 31 easily.

Below is a complete summary of its technical specifications.

The GE IC660EBA103 replaces older thermocouple blocks in Genius I/O systems. You do not need any external signal conditioners for thermocouple sensors. This block also supports hot-swapping for maintenance without system shutdown. Consequently, it suits furnace monitoring and temperature control applications.
