TAC relay - Electronic timer, windshield wiper control module



The electronic timer TAC is a train windshield wiper monitoring module. A simple turn of a cals potentiometer allows to set the wiping sequence from one every 3 seconds to one every 30 seconds. The plug-in design offers secure locking feature for maximum ease of maintenance (no wires need to be disconnected or other hardware removed for relay inspection or replacement).
The resistance to impact and vibration is conform to standards in force for Railway Transported Equipment.
Positive mechanical keying of relay to socket is built into relay and socket during manufacture and terminal identifications are clearly marked on identification plate that is permanently attached to the relay.
The TAC module is pluggable in the following sockets: EA 102 A, EA 102 AF, EA 103 AF, EA 104 A, EA 104 AF, EA 105 AF, EA 112 AF.


The TAC electronic timing module is designed for windshield wiper control
applications with a programmable timing function.
