FDCI222 Input Module 4 Inputs, built-in isolator

For the connection of 4 independent circuits of potential-free, make-or-break contacts for the indication of technical states (e.g. door or ventilation control) or for alarm actuation (e.g. sprinkler alarm). 4 inputs for potential-free contacts. Input lines are monitored for open line and short-circuit (termination resistors). Inputs can be independently configured via the fire control panel for status or alarm messages. Status indication by LED. Power supply via FDnet/C-NET. Input module incl. 8 resistors and 2 mounting feet for TS35 U-rail.
