5.3 Monitored LED module - BR 50-LED-M
The function-monitored LED module for the Intense BR 50 signal tower can be used easily in combination with
other function modules for safety-relevant applications, for example. The diagnosis channel of the module (alarm
contact) can be incorporated here into a higher-level control system as a feedback signal.
A maximum of 3 modules can be used.
