Digital I/O module / decentralized
Siemens Building Technologies (BT HQ CC OC)
For the connection of 1 circuit of potential-free, make-or-break contact for the indication of technical states (e.g. door or ventilation control) or for alarm actuation (e.g. sprinkler alarm). For the decentralized control of fire doors, ventilation and air conditioning.
1 input for potential-free contact. The input line is monitored for open line and short-circuit (termination resistors). The input can be configured via the fire control panel for status or alarm message. 1 output configurable as a potential-free relay contact (AC 22 V, 2 A) or as a monitored circuit (DC 30 V, 2 A).
Status indication by LED. Power supply via FDnet/C-NET in potential-free mode. Monitored mode requires additional DC 24 V power supply.
Input/output module incl. 3 resistors and 2 mounting feet for TS35 U-rail.
