10.2 Output
10.2.1 Auxiliary voltage output
The auxiliary voltage is provided to activate the digital input (or sensors) with floating contacts and
is galvanically isolated from the system and the inputs (testing voltage 500 V). The ground of the
auxiliary voltage and the ground of the digital input are electrically interconnected.
Output voltage:
Approx. 24 V, max. 28 V
Output current:
Maximum 250 mA, short-circuit proof, not stabilised
10.2.2 Relay outputs
Alarm relay:
1 Alarm relay with changeover contact
Standard relay:
3 relays with NO contact for limit value messages (can be configured as NC contact).
!
Note!
It is not permitted to mix low voltage and safety extra low voltage (do not mix SELV circuits and
low voltage).
Response time:
1 s
Maximum DC contact load:
50 V / 300 mA (steady-state, without destroying input)
Maximum AC contact load:
230 V / 3 A (steady-state, without destroying input)
