LB-499-REL2 Relay Module
This module of additional relays is equipped with 2 relays with a NC and NO terminal.
The module may be connected to the following devices:
The module enables the control of any working devices, where it is necessary to switch large currents and at the same time provide full galvanic isolation with an LB-480/LB-490 recorder.
The relays may be operated manually, via software (from LBX software serving as a digital output) or as an alarm output switched on/off in response to different alarms programmed in the device.
Example of connection layout
Relay No. 1 switches on the light signalling.
Relay No. 1 switches off the sound signalling (when a relay is switched on, it switches off the sound signalling, and at the same time LB-480 control failure triggers an alarm).
