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.

Function diagram
A ON-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.
