Models SC-IM9.. Interface Modules

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.

Models SC-IM9.. – Safety Controller Interface Modules Primary Safety Device Requirements These Interface Modules are driven by the safety output channels of the SC22-3 Safety Controller (model SC-IM9A by two safety output channels, SC-IM9B by four, and SC-IM9C by six). These Interface Modules must be used only with the SC22-3 Safety Controller and must be monitored via the Controller's EDM inputs (see Figure 2 and the Warning on page 5). Refer to the SC22-3 Safety Controller manual (p/n 133487), Section 3.
