FDCIO222 4 In/ 4 Output Module, built-in isolator

For the connection of 4 independent, 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. 4 outputs with 4 potential-free relay contacts (AC 250 V / 4 A) for fire control installations. Status indication by LED. Power supply via FDnet/C-NET. Input/output module incl. 8 resistors and 2 mounting feet for TS35 U-rail.
