Time Relay / Emergency Stop

SAFEONE DNSR

The DNSR time relay is ideal for enabling two control circuits, optionally preconfigured with release-delayed or pull-in-delayed contact outputs. With the 33SR20 variant, the time delay can also be set directly on the device using two potentiometers.

The DNSR emergency stop relay is ideal for monitoring an emergency stop circuit. Preconfigured with release-delayed contact outputs and instantaneous non-delayed contacts.

Your advantages summarised.

2 control circuits with one single-channel and one dual-channel contact each.

2 terminals for time setting release, provided that the two-channel contacts are adjustable via potentiometer.

Choice of instantaneous, off-delayed or on-delayed contacts.
Individual time settings are parameterised ex works according to customer specifications. Optionally, the delay times of the safe contacts can be set via a potentiometer.

All contacts are designed as NO. The single-channel contacts can be electrically designed as NC by re-parameterisation.

The connection panel is attached to the side of the unit.

The pluggable terminals are interchangeable.

Inputs and outputs are checked for plausibility.
