DESCRIPTION: Plug-in LED indicating module for sockets
LED COLOUR: Green
Series 99 modules for sockets
Plug-in modules are convenient add-on devices for relays which offer LED indication (for ease of viewing relay status from a distance), diode protection, RC circuits, bypass and timing facilities for all socket-mounted plug-in relays.
The modules simply plug into specific sockets to enhance the relays functionality.
Depending on module selected, they can provide;
Suppression of coil back emf on switch-off
LED indication to show when the coil in energized
Protection against reverse polarity applied across the coil terminals
By-pass of troublesome leakage currents in the coil circuit
LED module
Used for AC and DC , the LED indicator illuminates when the relay coil is energized.
Essential to connect + to terminal A1 in DC applications.
