Dry Contact Sensor Probe

with 16 dry contact inputs & 4 dry contact outputs

The ServersCheck Dry Contact (voltage free contact) sensor monitors the state of any electrical dry contact output enabled device and can control equipment using one of its 4 outputs. Examples of such devices: alarms, generators, control relays, valves, fans, HVAC, ...

The sensor has 16 distinct dry contact inputs. They can be configured (on a per port basis) to monitor either a normal open (NO) or normal closed (NC) state. Not only can you define the normal state but you can also set a minimum time that a state should be in before triggering an alarm.

On top of the 16 inputs, the device also features 4 outputs. With the outputs you can control equipment. For example you could remotely or automatically start a backup air conditioning unit, start a pump when a water leak is detected.
