PR102.24.2.2
Programmable relay
WARNING
Switch off the supply voltage before working on the relay or
connecting or disconnecting it with other devices or PC. Switch the
supply voltage on only after all works has been completed.
CAUTION
The program runs after transferring it to the relay. It is recommended
to transfer the program before wiring the relay. Otherwise ensure that
all peripheral devices are disconnected from relay outputs before
transferring the program.

3. Wire the device using the supplied terminal blocks.
Removing:
1. Take off the terminal blocks without disconnecting wires.
2. Insert a screwdriver into the eyelet of the slide interlock.
3. Loosen the slide interlock and then remove the relay from the DIN rail.
PR102 is equipped with plug-in terminal blocks which enable quick
replacement of the device without disconnecting the existing wiring.
