Adapter assembly for field controller units

A field controller replacement unit, comprising:

• a bracket including a plate having a first side and an opposing second side with a plurality of feet extending from the second side;
• a field controller coupled the first side of the plate, the field controller including an interface positioned along a peripheral sidewall thereof;
• and
• a connector assembly coupled to the second side of the plate, the connector assembly including:
• a circuit board;
• a terminal block coupled to the circuit board;
• and
• a connector coupled to the circuit board with a plurality of wires, wherein the connector is in releasable engagement with the interface of the field controller, electrically coupling the field controller to the circuit board;
• wherein the plurality of feet are configured to engage with mounts on a housing of a base unit to facilitate mechanically coupling the bracket to the housing;
• and
• wherein the terminal block is configured to engage with a corresponding terminal block on a base circuit board disposed within the housing of the base unit to electrically couple the circuit board and the field controller to the base circuit board.
