3.8.3. Outputs

The output drivers for the

instrument are high side drive and are capable of driving up to

400mA each. This configuration allows for the direct connection of the

instrument

outputs to

most types of PLC.

The voltage applied to the

the instrument’s positive power supply terminal (+)appears on the

output lines (Over, Pass and Under) when the outputs are active (eg. to connect to a PLC
c24V to the common terminal). The outputs can then be connected directly to PLC
inputs.

To drive external loads (eg. relays), connect the output line directly to the positive side of the
relay coil. Connect the negative side of the relay coil to COMMON. It is recommended that
fly-back diodes or transient suppressors be fitted across relay coils to limit switching noise.
