TTBCR 200 relay - Delay on drop-out, instantaneous



The TTBCR 200 time delay relay has 2 changeover simple break contacts with 1 instantaneous contacts and 1 delayed contacts on drop-out fully programmable (with dipswitch) from 0.5 seconds to 4 seconds. The access to dip switch is available by removing time delay cover. This feature prohibits frivolous field time delay setting.
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 TTBCR 200 timing relay is designed for applications with a programmable timing function used for example in HVAC and lighting.
