The PK4 (AWZ515) 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. It features a serial fuse in the circuit of the relay (BELL+, SYGNAL+). Power supply: 10÷14VDC. Relays: 4x REL-C/NO/NC, 2A@30VDC/50VAC. Protections: fuses 2A, 0.5Amp.
