GE IC693UEX122AP1 – Micro Expansion Unit for Series 90-30 Systems

The GE IC693UEX122AP1 adds I/O capacity to Series 90-30 PLC systems in a compact form. This micro expansion unit measures 90 mm in width and 110 mm in height. It has a depth of 70 mm, so it fits small enclosures easily. The unit weighs 0.45 kg, making DIN rail mounting simple and secure.

I/O Capacity and Built-in Channels

This micro expansion unit provides 12 digital input channels and 8 digital output channels. The GE IC693UEX122AP1 accepts 24V DC signals from field sensors and switches. Each input channel draws 7 mA at 24V DC for reliable detection. The outputs use transistor switching rated for 0.5 amps at 24V DC. LED indicators show the status of all 20 I/O points clearly.

Communication Interface and Expansion

The unit connects to the Series 90-30 CPU via a built-in serial link. The GE IC693UEX122AP1 communicates using the SNP or SNPX protocols. A single twisted-pair cable supports distances up to 200 meters from the CPU. You can add up to 8 expansion units to a single Series 90-30 system. The unit automatically configures itself when connected to the network.

Internal Architecture and Component Layout

The micro expansion unit contains one main circuit board inside its plastic housing. The GE IC693UEX122AP1 includes a dedicated microcontroller for I/O processing. A removable terminal block accepts all field wiring connections easily. The unit stores 100 µF of capacitance for power supply filtering. No backplane or rack is necessary for this standalone unit.

Power Requirements and Environmental Tolerance

The GE IC693UEX122AP1 draws 150 mA at 24V DC from an external supply. It also draws 50 mA at 5V DC from the communication link. The unit operates reliably from 0°C to 60°C ambient temperature. It tolerates humidity levels up to 95 percent without any condensation issues. The enclosure carries an IP20 rating for indoor panel installation.

Below is a complete summary of its technical specifications.

The GE IC693UEX122AP1 expands I/O capacity without using a full-size rack. You do not need any special configuration software for basic operation. This unit also supports hot-swapping for maintenance without system shutdown. Consequently, it suits small machines and remote I/O applications.
