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:
Function

LV1
relay switches
when exceed-
ing the limit
value of
limit value 1
Isolated change-over con-
tact
Terminal 1: c / Central contact
Terminal 2: no / closing contact
Terminal 3: nc / Break contact
programmable:
- Permanent contact
- Impulse
(1-99 seconds/minutes)
- interval
(1-99 seconds/minutes)
- Area of lower limits
- Switches when the limit
value is exceeded once, twice
or three times
