The GE Fanuc IC693MAR590 is a 120 V AC Input/Relay Output module designed for seamless integration with the Series 90-30 Programmable Logic Controller. This module features eight input points that share a common power input terminal, alongside eight normally-open relay output circuits. The output points are divided into two groups of four, each with its own common power output terminal, providing flexibility for various applications. The module's input characteristics allow it to interface with pushbuttons, electronic proximity switches, and limit switches, requiring only an external AC power supply for operation. Each relay circuit supports an output switching capacity of 2 Amps, making the module suitable for controlling load devices such as solenoids, indicators, and motor starters. While it does not incorporate fuses, an LED block on the module indicates the status of the input and output points. Additionally, a door card is included for users to record circuit identification or wiring details, featuring a red color code to indicate its high-voltage designation. The IC693MAR590 can easily be installed in either a 5-slot or 10-slot baseplate within a Series 90-30 PLC system, as it is compatible with any I/O slot. Technical specifications include eight input channels, eight outputs, an input voltage range of 0 to 132 V AC, an output voltage range of 5 to 30 V DC or 5 to 250 V AC, a maximum output load of 2 Amps, a response time of 15 milliseconds, and a power consumption of 80 mA from 5 VDC and 70 mA from relay 24 VDC.
