9.16 Relay connection
The door video module relay (TVHS20000(S) / TVHS20010(S)), security module TVHS10040 /
TVHS20340 and monitors TVHS20200 / 210 / 220 have maximum loads of 2A 30VDC / 0.5A
125AC. An overload will cause the device to malfunction.
Be sure to determine the power consumption of your current door opener / motorised lock. If the
permissible current is exceeded, we recommend connecting an external relay.
The door video module has a separate 12V DC voltage output. This allows an external auxiliary
relay to be clamped on directly without further power supply.
