Application and Wiring Examples
The DIS safety relay monitors two devices with OSSD outputs in
The DIS safety relay logic setting is 6: (IN1 AND IN2) OR L12 with
automatic reset. The output terminals 34 and 44 are designed to tolerate higher
capacitance loads (but lower resistive load) as compared to terminals 14 and
24.

The EM safety relay in
expands the number of outputs of the DI
safety relay. The single wire safety signal from terminal L11 to L12 instructs
the EM safety relay to turn on and off. The EM safety relay outputs mimic the
DI safety relay outputs. The DI safety relay monitors contactors K1…K6 and
the status of the EM safety relay by sourcing the reset signal from the X32
terminal on the EM safety relay.
