Description of the relay outputs

All relay outputs are designed as neutral contacts. This means the full
range of connection options is available to you. This facilitates the
switching of mains power, external power and direct switching of
inputs, e.g. a process control procedure is implemented.
Durability of relays
Please note the loading capacity of the relay and the overall loading
capacity (see Technical Data)!
Excessive loading may destroy the relay.

LV1 and LV2 limit value outputs

Two isolated relay contacts are provided to issue limit value exceed-
ed alerts. For both contacts, the limit values, the number of times the
limit value has been exceeded up to switching as well as the switch-
ing function itself are freely programmable:
