Alarm Connection
– J5, J6, J7, J10 and J4
AI 1 to 16 (Alarm-In)
: Use external devices to signal events to the Recorder. Mechanical or electrical switches can
be wired to the
AI
(Alarm-In) and
GND
(Ground) connectors. The voltage range is from 0V to 50V. When the electrical
switch is wired, the threshold voltage for NC (Normally Closed) is below 2.5V and for NO (Normally Open) is above
2.6V, and it should be stable at least 0.5 seconds to be detected.
GND (Ground)
: Connect the ground side of the Alarm input and/or alarm output to the GND connector.
NOTE: All the connectors marked GND are common.
NC 1 to 2 /NO 1 to 2 (Relay Alarm Outputs):
The Recorder can activate external devices such as buzzers or lights.
Connect the device to the
C
(Common) and
NC
(Normally Closed) or
C
and
NO
(Normally Open) connectors.
NC/NO
is a relay output which sinks 0.5A@125VAC and 1A@30VDC.
See
Chapter 3 ─ Configuration
for configuring alarm
output.
