Terminal 97 00

Relay outputs
Only devices with optional motherboard and B-Client HR30 ‘Door control’ software option.
Two potential-free relay outputs with one change-over contact each are available.
Contact loading capacity: 30 V AC/DC; max. 2 A
The function and assignment of relays 1 + 2 depend on the settings of the terminal software.
For inductive loads that are supplied with direct current, the included diode (a freewheeling
diode) must be connected parallel to the load to suppress interference. Make sure that the di-
ode is connected in reverse-bias direction. When using an AC voltage power supply, the in-
cluded varistor type S10K30 must be connected in parallel.
The diode or varistor must be connected directly to the load and must
not
be fitted in the ter-
minal.
