Connecting the OPLC to the EX90-DI8-RO8
An OPLC, such as the M90 micro-OPLC, is connected to the EX90-DI8-RO8 as shown below, via a category 5
shielded twisted pair cable (CAT 5, STP), terminated by RJ45 connectors. The cable provided with the EX90-DI8-
RO8 is one meter long; cables of other lengths are available by separate order.
Note that the cable must be earthed on the M90 side, via the yellow-green wire.
To avoid damaging the system, do not connect or disconnect the device when the power is on.
