Contact Alarm Expander
The Contact Alarm Expander™ is a small, DC powered block of solid-state relays that makes it possible to convert a standard "open/closed" contact indicator into several isolated and varying contact configurations. Each of these outputs can be read simultaneously by different monitors. The Contact Alarm Expander takes a normally dry contact as input and relays the state of this contact to two normally open contacts, one normally closed contact, and one 540/270 ohm contactor.
In application, this device makes it possible to monitor air dryer equipment remotely without interfering with existing, on-premises contactor alarming.
