Timing relay ETR and DIL ET
Both relays feature a large timer range. Whether it is for short signal extensions or extremely long processes, multiple time ranges from 0.05 seconds to 100 hours can be accurately set. A remote potentiometer can be connected to Z1/Z2 on the ETR 4-70/DILET70, and the time can be set externally. 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, with 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.
