Terminal Block Sold Separately

The 1250-20 Power switching module provides switching for AC or DC power supplies and current sources. Switching networks may be configured from the ten independent DPST relays provided. The 1250-20 switches up to 8 A at 250 VAC rms or 5 A at 48 VDC. Relay contacts are monitored to provide user selectable confidence checking. Each channel provides mounting holes to allow the addition of shunt and series elements such as arc suppressors, filters, etc. A fused +13 V DC supply is provided for driving external relays. Separate connections to both sides of the relay allow each channel to function independently or to be configured as custom networks.
