PR100.24.2.1
Programmable relay
WARNING
Before working on the device, power it off as well as all connected
equipment.
WARNING
The device must be powered off before connecting to peripheral
devices or PC. Switch on the power supply only after the wiring 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. Installation
Fig. 1 Dimensions
Installation:
Fig. 2
1. Place the device on a DIN rail as shown in Fig. 2.
2. Press the device firmly against the DIN rail in the direction of arrow 2
until the latch locks.
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.
PR100 is equipped with plug-in terminal blocks which enable quick
replacement of the device without disconnecting the existing wiring.
