DESCRIPTION: Plug-in RC module for AC and DC lines
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
RC circuit module
RC circuit modules are used for AC and DC applications.
The reverse voltage peaks of the coil are limited by the RC module to approximately 2.5 times the nominal supply voltage.
