CI Safety Relay
(Cat. No. 440R-S13R2)

Application and Wiring Examples

The application and wiring examples in this chapter show you how to put the
inputs and outputs together to create an operating safety system. These circuit
diagrams are examples; many features are interchangeable between relays.

diagrams.
In Figure 42, the CI safety relay is monitoring a device (an E-stop push button)
with mechanically operated contacts. The CI safety relay is configured for
monitored manual (MM) reset. The output turns on if the E-stop is released
and the reset push button is pressed and released between 0.25...3 seconds. The
CI safety relay monitors the status of the two output contactors, K1 and K2. If
either fails to close their N.C. contacts, the CI safety relay does not reset. An
auxiliary signal, terminals 41/42, is sent to the PLC when the E-stop is pressed.
