Auxiliary Relay Cards

When you have to switch large loads with open collector outputs or small relays, the auxiliary relay cards can be used. The relay card will isolate and ensure that the larger electrical currents do not directly interact with your delicate electronics. This not only protects your circuits from electrical noise, voltage spikes, and other harmful conditions but also enhances the reliability and longevity of your overall system.

Elsema relay cards use industrial grade relays which conforms to several safety standards, UL, C-UL and VDE.
