EMERSON IC694MDR390 8-Input 24VDC RX3i Mixed I/O Module

The 24Vdc 8-Input/8-N.O. Relay Output module provides eight isolated input points with one common power input terminal, and eight isolated normally open relay circuits in the same module. Figure 252: IC694MDR390 The input circuits can have either positive or negative characteristics in that they sink or source current to/from the input devices to/from the user common. Input characteristics are compatible with a wide range of usersupplied devices, such as pushbuttons, limit switches, and electronic proximity switches. Current through an input results in a logic 1 in the input status table (%I). The relay output circuits are arranged in two groups of four circuits each. Each group has a common power output terminal. The normally-open relay circuits are used for controlling output loads provided by the user. The output switching capacity of each output is 2 Amps. The relay outputs can control a wide range of user-supplied load devices, such as motor starters, solenoids, and indicators. The top half of the outside left edge of the insert is color-coded blue to indicate low-voltage circuits and the bottom half of the outside left edge is color-coded red to indicate high-voltage circuits. This module can be installed in any I/O slot in an RX3i PLC System. Module does not support insertion into or removal from an RX3i Universal Backplane which is under power. Power for the internal relay circuits is provided by the +24Vdc bus on the backplane. The user must supply the AC or DC power to operate field devices. There are no fuses on this module.
