Electronic timer CT-ERE
ON-delayed with 1 c/o (SPDT) contact
The CT-ERE is an electronic time relay with ON-delay. It is from the CT-E range.
The CT-E range is the economic range of ABB‘s time relays and offers a cost effective price-performance ratio for OEM users. This is achieved by simplified functionality and results in the simplest of setup procedures. The CT-E range is ideally suited for repeat applications.

Application
Their conception makes the CT-E range timers ideal for repeat applications.
Operating mode
The fine adjustment of the time delay is made via the front-face thumbwheel.

Function diagram
AON-delay (Delay on make)
Applying control supply voltage starts timing. When the selected time delay is complete, the output relay energizes. If control supply voltage is interrupted, the output relay de-energizes and the time delay is reset. Interrupting control supply voltage before the time delay is complete, resets the time delay. The output relay does not energize.
