Reviews for Safety Relay Modules

Decent safety relay. Documentation on device is poor, especially wiring.

I have used this E-Stop Relay on several Control Panels and not one has failed or given me any problems at all. Very good unit and the price is great. Very happy with the performance.

Product is configurable and works as required, for a good price.

Simple easy setup and good value. Combined with Datalogic safety light curtain # SG4-30-075-00-E.

I have used a bunch of these over the years, but still have to occasionally call tech support to figure out the setup. The instructions are somewhat cryptic and if your configuration doesn't match one of the few examples given then it is a guessing game as to how to wire it. There is no explanation of what the different terminals do or the inner workings of the device. I am not sure why Automation Direct doesn't come up with their own instruction manual for this instead of relying on the one from Dold.

I have used various brands of hard wired estop controllers before. This is as good as any and the price is right. In conjunction with the Dold extension safety relays it makes for a very safe and robust estop system. Reasonably easy to work with and reliable. Never had a failure so far.

Easy to install and connect. Retrofitted an older machine from foot pedal to two-hand switches for safety.

Worked great once we found switches to set-up relay. Instructions are unclear on the location of the switches. Otherwise great product. Used with Contrinex Light Curtains in automatic mode.

I have used these in a few applications, and keep them on hand for emergencies that come up. They saved the day again when a pair of contactors failed (over-designed for the application, but that's another story). For the cost, they are hard to beat, and operate just like everything else you might have used. The features are typical- 2 channel input, manual or automatic reset, and switchable cross-fault monitoring. The quality seems to be great. I don't see why you would pay the large prices of a large American company (who I've been told relabels their safety relays sourced from a European vendor anyway) when you could buy these. Until they give me a reason, I will continue to use them. The only problem I've had so far is with a safety prox that uses OSSD outputs. I believe the light curtain version would have worked, but this relay faulted the sensor. It was probably a misapplication on my part.

We use this safety relay with the Datalogic SG4-30-xxx-OO-E light curtains. Easily wired when following the A-D errata sheet as the wire colors of the A-D offered cables differ from the colors given by the manufacturer. We use the light curtains in the auto-restart mode, so you must place both switches in the relay into the up position. Great value!
