GE IC693UDR001NP1: Compact Micro PLC Unit for Small Automation Tasks

Core Processing Capabilities

The GE IC693UDR001NP1 combines a CPU, power supply, and I/O in one compact unit. This micro PLC unit executes ladder logic for small machine control applications. It manages up to 64 local I/O points without additional expansion modules. Consequently, the module provides an economical solution for standalone automation systems.

Physical Dimensions and Enclosure Design

This micro PLC unit measures 90 mm in total height. Its width reaches 75 mm for a compact DIN rail footprint. The unit depth stands at 60 mm including the terminal blocks. You will find a molded thermoplastic housing with integral mounting tabs. The GE IC693UDR001NP1 weighs approximately 0.35 kilograms for panel or DIN rail mounting.

Processor and Memory Configuration

The GE IC693UDR001NP1 houses an 8-bit microcontroller running at 10 MHz. This CPU executes basic ladder logic instructions with 5 ms scan times. The unit contains 6 KB of flash memory for firmware and user program storage. It also includes 2 KB of battery-backed RAM for runtime variables and data. A non-volatile EEPROM retains key parameters without any battery backup.

Integrated I/O Channels and Ratings

This micro PLC unit provides 8 digital input channels built into the housing. It also includes 6 digital output channels for direct actuator control. The inputs accept 24 V DC from limit switches and proximity sensors. Each input draws 7 mA at 24 V DC with a 2 ms response time. The outputs are relay type rated at 2 A at 250 V AC.

Power Supply and Input Voltage

The GE IC693UDR001NP1 accepts 24 V DC power directly from a field supply. The internal power supply generates 5 V DC for logic circuits. Input voltage range spans from 20 to 30 V DC continuously. The unit draws 150 mA at 24 V DC with all outputs off. Full load adds up to 1.5 A across all six relay outputs combined.

Communication Ports and Programming

This micro PLC unit offers one RS-232 port for programming and monitoring. A 9-pin D-sub connector serves as the programming interface. The unit supports serial communication with an HMI or operator panel. A built-in real-time clock provides time-stamped event logging. The clock uses a supercapacitor that holds time for 14 days without power.

Status Indicators and Diagnostic Features

The GE IC693UDR001NP1 provides 16 LED status indicators. Eight green LEDs show the status of each input channel. Six red LEDs indicate which output relays are energized. A green power LED illuminates when the unit receives 24 V DC. A yellow run LED flashes during normal program execution. A red fault LED signals hardware or software errors.

Energy Storage and Protection Features

The GE IC693UDR001NP1 incorporates two 220 µF capacitors for power filtering. These capacitors provide 20 ms of hold-up time during power dips. Total stored energy reaches approximately 0.07 joules at nominal voltage. The unit includes overvoltage protection on all input channels. Output relays feature built-in snubber circuits for extended contact life.

Installation and Programming Notes

You must mount this micro PLC on a standard 35 mm DIN rail. Always connect the ground terminal to the system earth before applying power. Then, write your ladder logic using GE Proficy Machine Edition software. The unit requires a standard programming cable for initial configuration. Regular program backups prevent data loss during unexpected power outages.
