Interface Modules for Use with the SC22-3 Safety Controller
WARNING . . .
This Interface Module is not a point-of-operation guarding device, as defined by OSHA
regulations. It is necessary to install point-of-operation guarding devices, such as safety light screens and/or hard guards, to
protect personnel from hazardous machinery. Failure to install point-of-operation guards on hazardous machinery could lead
to serious injury or death.
Features
• Provides isolated safety output contacts for the SC22-3 Safety Controller, which has
solid-state outputs and external device monitoring (EDM) capability.
• Designed specifically for use with one, two or three Safety Controller safety outputs
(see Models table).
• Features three normally open redundant-output channels and one normally closed
monitoring output channel for each safety output.
• Has contacts rated at 10 amps.
• Operates on 24V dc, supplied by the Safety Controller.
• Mounts to standard DIN rail.

Overview
Interface Modules SC-IM9.. operate on 24V dc inputs and provide isolated redundant output
channels for interfacing the Safety Controller's solid-state 24V dc outputs to ac safety circuits.
The normally open safety contacts of the Interface Module will follow the action of the safety
outputs from the Safety Controller within 3 milliseconds when going from closed to open (for
other response times, see Specifications). All Interface Module contacts are rated for up to
690V ac/dc at up to 10 amps.
The SC-IM9.. Interface Modules offer a series connection of normally closed contacts (labeled
21-22 on each contactor) for monitoring by the external device monitoring (EDM) function of
the Safety Controller. These forced-guided (mechanically-linked) contacts allow the Safety
Controller to detect failures of the SC-IM9.. Interface Module, and at a minimum, must be
monitored in applications requiring Control Reliability per OSHA/ANSI or Category 3 or 4 per
ISO13849-1.
