Relay Transformer Power Modules

Relay modules contain components that make switching and connecting easier, and act as indictors to show if the module is powered and if the relay is active. On the input side of a standard single-channel relay module, is the screw terminal block. This is the part of the module that comes in contact with the mains, and screw terminals make it easier to connect thick mains cables. The three connections on the terminal block are connected to the normally open, normally closed and common terminals of the relay. An input jumper is used to supply power to the relay coil and the ‘relay status LED.’ The output connectors are wires that are suitable for hardware connection.

Phoenix Contact Power Modules are pluggable power supplies with coil voltage ratings from 24 to 500 VAC. Phoenix Contact Power Terminal Blocks are designed for the input of up to four potentials.
