Specification of Moeller Timer Relay ETR2 ETR4 Timers & Timing Relay ETR

Timing relays from Eaton 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

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.

Both relays feature a large timer range: Whether it is for short signal extensions or extremely long processes: Thanks to the relays of type ETR 2, ETR 4 and DIL ET multiple time ranges from 0.05 seconds to 100 hours can be set accurately. A remote potentiometer can be connected to connection Z1/Z2 on the ETR 4-70/DILET70. Using it the time can be externally set. If timing relays are installed in the enclosure or in control panels, the time setting can be undertaken when the door is closed.

Electronic timing relay ETR 4 features

The timing relay ETR 4 features a photo-electronic input. The opto-isolated input 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. The red LEDs signal the timing relay switching states. The green Power LED lights to indicate a voltage and flashes when the time is running.
