Timing relay ETR and DIL ET
 
Generous time range
Response delay is one of the most important time-dependent functions.
Timing relays from Moeller meet this requirement with a wide choice of
time ranges. Signals can be briefly extended or extremely long processes
can be catered for, with accuracy, thanks to the relays of type ETR 2,
ETR 4 and DIL ET multiple time ranges from 0.05 seconds to 100 hours.
For this purpose the time range is pre-selected, for example, with the
ETR 4 on the "Range" display. Them you fine-tune this setting
on the Time dial, where the setting is in "real time", allowing it to
be read directly on the scale. The mode of operation of the timing relay,
such as on-delayed or off-delayed, is simply determined with the aid of
the "Function" display.

Signalling, no problem
The opto-isolated input B1 allows actuation of the ETR 4 timing relay
from any point in the circuit. This saves one actuating contact and the
additional signal wiring. It is possible to actuate the signal input even
via voltages other than the control voltage.
For example, the ETR4 may be supplied at 230 V 50 Hz, while signal input
actuation is via 24 V DC.
