The IC693MDL931 module provides 8 relay outputs, where 4 are normally closed (N.C.), and 4 are Form C type relays. Form C relays offer both normally open (N.O.) and normally closed (N.C.) contacts, providing more flexibility for your needs. Each output can handle up to 8 amps, and all relays are isolated from each other, meaning each one has its own separate power output terminal. This module is ideal for controlling devices like motor starters, solenoids, and indicators, but you will need to supply the necessary AC or DC power to run these devices.

The relays can switch:

    5 to 30 volts DC, or
    5 to 250 volts AC at 50/60 Hz.

There are no fuses on this module, so there’s no need to worry about replacing fuses. At the top of the module, you’ll find LED indicators that show whether each output is ON or OFF. The LEDs for this module are in the top row labeled A1 through A8 for each of the 8 points. The bottom row isn’t used.

Inside the hinged door of the module, there’s an insert with wiring information. When the door is closed, the circuit info is displayed on the inside, and you can write down any details on the outside surface if needed. The left edge of the insert is red, indicating this is a high-voltage module. The IC693MDL931 module can be installed in any I/O slot of a 5-slot or 10-slot baseplate in a Series 90-30 PLC system.

When wiring, follow the diagrams provided to correctly connect your load devices and power sources to the module.

In summary, the IC693MDL931 is a reliable module that provides strong 8-amp relay outputs. It works with both AC and DC loads, and since each output is isolated, there’s no interference between relays. The LEDs make it easy to see which outputs are ON or OFF, making it a perfect choice for controlling various devices safely and efficiently.
