Programmable logic controller output control circuits operating at twenty-four volts direct current and one hundred twenty volts alternating current. Each circuit incorporates a loop breaker for overcurrent protection alongside an interposing relay to interface control signals with field devices. The twenty-four volt DC loop includes terminals and a PLC output block connected to an interposing relay. The one hundred twenty volt AC loop includes terminal connections, a loop breaker, and relay contacts wired in series. These schematic representations guide the installation and wiring of control panels and automation systems.
