Electronic time relays ATI, BTI, SDT and MTI

With their robust design and many built-in functions, electronic timers ATI, BTI, SDT and MTI are ideal for OEMs and panel builders.

Features

Approvals

• Easy time setting

• Electrical noise immunity

• Mechanical shock and vibration resistance

• Time ranges 0.1 s to 30 min for single function Time ranges 0.05 s to 300 h for multi function Electronic timers

• Compact standard dimensions

• DIN rail or adaptor mounting

• Single function electronic timers featuring:

– ON delay – OFF delay or – star-delta start

• Multi function timer with 10 timing functions

• Function selector
