DIS Safety Relay
(Cat.No.440R-D22S2)
Figure 47 shows the DIS safety relay with only one device. The DIS and DI safety relays can
monitor one device by configuring the safety relay for OR logic. The DIS safety relay logic
setting is 1: (IN1 OR IN2) OR L12 with monitored manual reset. The second input (terminals S32
and S42) requires no connection. With solid-state outputs, the contactors K1 and K2 must be
24V DC powered coils. The DIS safety relay verifies that contactors K1 and K2 are off by
monitoring the mechanically linked normally closed contacts in the S34 circuit. When the DIS
safety relay is off, the auxiliary signal at terminal Y32 turns on and reports the status to a PLC.
Figure 47 - Single Input, Monitored Reset
The DIS safety relay monitors two devices with OSSD outputs in Figure 48. 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.
