Connect sensors to D-SUB 25 Pin as specified below.
You can connect dry-contact type sensors. In case of sensors with TTL output (5 Volts system), GND of
sensor must be connected to GND of DVMR unit and signal line to alarm input from D1 to D16 as shown
in following figure.
Short-circuit between any of D1 from D16 and GND is recognized as an alarm.
Relay output is output in case there is an alarm input, and is connected to external device using
COM-NO (Normal Open) or COM-NC (Normal Close) contact.
