OUT
The terminals labeled “OUT” are the two terminals of a normally open (Form A) solid-state
relay under the control of the node’s microprocessor. The maximum voltage that can be
applied to either of the terminals is 18V. The maximum load the relay can conduct is 100mA.
The maximum resistance when closed is 35 ohms.
IN AUX
The terminals labeled “AUX” are designed to connect to either normally open (Form A) or
normally closed (Form B) dry contact sensors. The maximum voltage that can be applied to
either of the terminals is +3.3V. The maximum resistance for a closed switch is 100 ohms; the
minimum resistance for an open switch is 10 Kohms.
IN A and IN B
Either or both of the terminals labeled “A” and “B” can be attached to a Sensicast touch
sensor. These terminals can also act as inputs for dry contact sensors in a similar manner to the
AUX connector.
Note
Touch sensors are an option for OAS nodes only.
