Relay Examples
Relay Type - Position Range
Selecting PosR relay type, you can cause the relay to energize when the actuator motor travels below 20%
of range and above 80% of range. Note in the example below that Relay 1 is set up to provide two trip
points. The first trip point (R11VAL) causes the relay to energize when the motor travels above 80%, the
second trip point (R12VAL) is set so the relay energizes when the motor travels below 20%.
