The Universal Relay board is used in a large range of machines.
There have been 3 different versions of the board all of which are interchangable.
Revision A had some tracks thickened up to protect them if incorrect fuses were fitted.
Revision B has a small change to the E-stop circuit allowing the relay to be controlled by an output of the NextMove to comply with changes in the machinerary directive
Revision C was inplemented in 2013. This board has the E-stop contact for the motor supply moved into the AC line rather than the DC path. This should prevent arcing of the E-Stop contact.
I am attaching Photos of the board with fuses and relays identified clearly as well as a schematic for the board.
