v.1.0
PK4
Relay module
Edition: 4 from 01.03.2018
Supersedes the edition: 3 from 10.07.2013 EN
1. Intended use.
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+).
2. Installation.
The set also includes 4 spacers fi=6mm for fixing the module to a flat surface (side panel of an enclosure,
a buffer PSU, etc.).
