The IC693MDR390 is a 24V DC Input/Output Relay module designed by GE Fanuc, featuring eight inputs and eight normally-open relay circuits integrated within a single unit. This module allows for compatibility with a wide range of input devices, including proximity switches, push buttons, and limit switches, and supports both negative and positive input characteristics, facilitating seamless interaction between devices and common power inputs. Inputs are grouped in sets of eight, while the relay output circuits are organized into two groups of four, each equipped with a common power output terminal.

The IC693MDR390 operates on user-supplied power for field devices and provides two amps of output switching capacity per relay, making it capable of controlling various load devices such as indicators, motors, and solenoids. The internal relay circuits draw from a +24V DC backplane bus, and the module supports output voltages ranging from 5 to 30V DC and 5 to 250V AC, accommodating currents of up to 2 amps per circuit with a maximum common output of 4 amps. Notably, there are no fuses within the module.

The device includes LED indicators that clearly display operational status (ON or OFF) and is designed with distinctly labeled input and output points, along with color-coded insert panels to minimize handling errors. The IC693MDR390 is compatible with both 5-slot and 10-slot baseplates, allowing for flexible installation in various input/output slots. The technical specifications include an input current of 7.5 mA at rated voltage and a frequency range of 50/60 Hz for AC output applications.
