Product Description

The IC693MDL646 module is a 24-volt DC positive / negative logic input module for the 90-30 series of Programmable Logic Controllers. It comes with 16 input points in one group sharing a common power input terminal.  The IC693MDL646 is designed to have either positive Logic or negative logic characteristics. Input characteristics make it compatible with a wide array of user supplied input devices such as limit switches, push buttons as well as proximity switches. Power to run the field devices is normally supplied by the user or an isolated +24VDC supply on the power supply.

At the top of the module, one can locate LED indicators which display the ON/OFF status of each point. The LED block is partitioned into 2 horizontal rows with 8 green LEDs in each row. The top row is labelled from A1 to A8 (Point 1 to 8) and the bottom from B1 to B8 (point 9 to 16). There’s an insert that goes between the inside and outside surface of the hinged door. Towards the inside, one will find the wiring diagram, and the circuit identification is located on the outside surface. The outside left edge of the insert is color-coded blue to show a low-voltage module. This module can be installed in any I/O slot in a Series 90-30 PLC system. Other specifications include an input voltage range of 0 to 30 VDC and input current of 7 mA. The on-state voltage is between 11.5 to 30 V and on-state voltage 0- +5V DC. On-state current rating is 3.2mA minimum and off-state 1.1mA maximum.
