GE IC609SJR100C – Series One Junior Basic Unit for Small Logic Control

The GE IC609SJR100C serves as a compact programmable controller for simple automation tasks. This basic unit measures 180 mm in width and 110 mm in height. It has a depth of 85 mm, so it fits small control panels easily. The unit weighs 0.85 kg, making DIN rail mounting secure and simple.

Processor and Memory Specifications

This basic unit contains an 8-bit microprocessor running at 4 MHz. The GE IC609SJR100C provides 1 kB of user program memory for ladder logic. It also includes 64 bytes of data memory for timer and counter values. The unit executes 6 milliseconds per 1,000 bit operations. A lithium battery retains program memory for up to 2 years during power loss.

I/O Capacity and Built-in Features

The GE IC609SJR100C includes 8 digital inputs and 6 digital outputs on the base unit. You can expand the I/O count to 40 total points using expansion modules. The inputs accept 24V DC signals with 7 mA per channel. The outputs use relay contacts rated for 2 amps at 250V AC. Four timer channels and four counter channels come built into the CPU.

Internal Architecture and Component Layout

The unit contains one main circuit board with all components integrated. The GE IC609SJR100C includes a removable terminal block for field wiring access. LED indicators show input, output, and power status for troubleshooting. A programming port on the front accepts a handheld programmer connection. The module stores 100 µF of capacitance for power supply filtering.

Programming and Environmental Specifications

You can program this basic unit using a handheld programmer or PC software. The GE IC609SJR100C uses simple relay ladder logic for easy learning. The device operates reliably from 0°C to 55°C ambient temperature. It tolerates humidity levels up to 90 percent without any condensation issues. The unit has an IP20 rating for indoor panel installation.

Below is a complete summary of its technical specifications.

The GE IC609SJR100C replaces older Series One Junior units in small control systems. You do not need any special programming skills beyond basic ladder logic. This unit also supports stand-alone operation without a PC for programming. Consequently, it suits small conveyors, packaging machines, and pump control applications.
