The PU3 (AWZ528) relay module is to be used in low-voltage installations. It is intended for controlling and status indication in e.g. alarm or access control systems. It may be used to control devices of high power consumption via OC outputs of alarm systems. Moreover, it ensures galvanic isolation of signals, power sources relating to the outputs of the module. The module is adapted for connection of cables with a maximum cross section of 1mm2. Power supply: 10÷14VDC. Relays: 3x REL-C/NO/NC, 1A@30VDC/50VAC.
