TPBAUN 400 relay – One-shot time delay with negative edge command

Categories: , , ,

Description

The TPBAUN 400 is a one-shot on pull-in or drop-out relay with 4 double
make / double break C/O contacts (form Z). The delay is triggered by the
negative edge of the command input and is fully programmable with a dip
switch from 0.25 s to 63 min. 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 TPBAUN 400 relay is pluggable in the following sockets: EA 102 B,
EA 102 BF, EA 103 BF, EA 104 B, EA 104 BF, EA 105 BF, EA 112 BF.

Application

The TPBAUN 400 timing relay is designed for heavy duty applications with
a programmable timing function used for example in HVAC and lighting.
