Siemens 500-896224 Interface Module TRI-R

The Siemens TRI-R interface modules are designed to monitor a normally open dry contact.  The interface module reports the contact’s status to the control panel.  The TRI-R incorporates an addressable Form C relay.  The Siemens 500-896224, TRI-R relay and contact device input are controlled at the same address.  For the MXL system, the relay and input contact can be controlled as a separate function. The relay is typically used where control or shunting of external equipment is required.
