AutomationDirect: Safety relay modules

AutomationDirect’s Dold UH6932 and Dold UH6937safety relay modules consist of safety relays that are controlled by built-in monitoring functions and assure a reliable opening and closing for safety applications.

These speed safety relays provide overspeed, under speed and/or standstill detection for single- or three-phase motors by monitoring either external proximity sensors mounted on a rotating element of the motor or load, the frequency of the motor power signal or the remanence voltage (back EMF) of the motor signal.

The Dold UH6932 speed monitor relay modules have 2 PNP or NPN sensor inputs and 2 N.O. positively driven and 2 semiconductor monitoring outputs.

The Dold UH6937 frequency monitoring relay modules require no external sensors and provide 2 N.O. positively driven and 2 semiconductor outputs for monitoring.

The new safety speed relay modules start at $380.00 and have a 1-year warranty.
