DIS Safety Relay
(Cat.No.440R-D22S2)
Figure 46 shows the DIS safety relay with only one device. The DIS and DI
safety relays can monitor one device by configuring the 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 46 - Single Input, Monitored Reset
The DIS safety relay monitors two devices with OSSD outputs in Figure 47 on
page 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.
