securityProbe 5ESV-X20 20 Extra Dry Contact Inputs
The 20 extra dry contact inputs on for example, the securityProbe 5ESV-X20, (or
securityProbe 5ESV-X60) can be configured as
inputs only
up to 5 Volts in normal
operation. In opto-isolation mode they can input up to 30 Volts DC. This will protect these
inputs and the unit from high voltages and spikes.
Opto-isolators provide complete electrical separation between the securityProbe 5ESV-
X20 or X60 and the dry contact. The base units are therefore protected against possible
large voltage spikes caused by lightning for example.
The figure below shows the JUMPERS (on the dry contact board) set up to provide opto-
isolators support. Opto-isolators provide complete electrical separation between the
securityProbe 5ESV-X20 and X60 and the dry contact.
Please refer to the rear panel of the securityProbe 5ES above for the other connections
on the rear panel as they are exactly the same in functionality.
The OID for the extra dry contact inputs is:- .1.3.6.1.4.1.3854.1.2.2.1.18.1.3.<port>
Extra dry contact input practical applications:
The extra dry contact inputs can be used to monitor many types of equipment, for example, you
can run the connection from warning lights on alarm panels to the dry contact inputs, so that
when the warning light on the alarm panel is activated, the dry contact is triggered in the units
web interface, thus allowing you to send notifications via emails or SNMP traps.
