Relay Cards For Communication Through Potential-Free Contacts

The relay cards are an option for the UPS series with expansion slot. It provides potential-free contacts at the outputs, which can be configured optionally as N/O or N/C contacts and which can be used as binary input for the SPS or building control systems. Tapping occurs via a sub-D-slot and, in case of the programmable PRO design, via a clamping block designed for supply voltage potential.
