Geovision GV-Relay V2 User Manual

GV-Relay V2

The GV-Relay V2 is designed especially for driving higher voltage output devices,
and it is controlled by other GV devices, such as GV-Video Server, GV-Compact
DVR, GV-IP Camera, GV-DSP LPR, GV-I/O USB Box and GV-NET/IO Card V3.1.

The GV-Relay V2 provides 4 relay outputs, and each output can be set as normally
open (NO) or normally closed (NC) independently as per your requ irement.

Note: The difference between GV-Relay V1 and GV-Relay V2:
GV-Relay V1 must work with GV-IO Box together, while GV-Relay V2 must
work with GV IP devices, GV-I/O USB Box or GV-NET/IO Card V3.1.
