Input/output module 'Transponder'

Stock no. S24218-B102-A1

Stock no. S24218-B102-A1

For connection of collective fire detectors (GMT/conventional line, GMT/conventional line with shunt Zener diode barrier (SB3) for explosion-hazard areas). For monitored controls of e.g. smoke dampers, alarm devices, door magnets and extinguishing activation devices (adhere to country-specific instructions). Monitored signal input for status and alarm messages or for acknowledging technical status.

The 2 inputs/outputs can be parameterized autonomously in each case as detector line collective, contact input, control output, control output and input as acknowledgement with selectable monitoring time frame. Status indication by LED.

Transponder incl. 2 Transzorb diode 20 V, 8 resistors and 2 mounting feet for TS35 U-rail.
