How to Select an Interface Relay for PLC Outputs
A step-by-step guide to matching PLC output type, coil voltage and current, contact rating, and socket style when selecting an interface relay.
The Schneider Electric TPRBCPFB is a TeSys Island bus coupler that connects a group of TeSys starters to a Profibus DP automation system. Supplied by 24 V DC at up to 3 A, it provides the Profibus DP fieldbus port plus an Ethernet service port with an embedded web server for diagnostics.
The TPRBCPFB is the left-most module in a TeSys island, giving the group a Profibus DP link to the PLC; it manages the complete island of up to 20 modules through SoMove or EcoStruxure Machine Expert, and its embedded web server covers maintenance without needing the automation controller.
