Abstract: An improved coupler control circuit board which can be positioned in an environmentally protected location for controlling an uncoupling operation of a mechanical type coupler mechanism utilized to connect adjacently disposed ends of a pair of passenger transit type railway cars. Such coupler control circuit board includes a power supply device connected to receive a predetermined input voltage. The power supply device reduces such predetermined input voltage received therein to a suitable predetermined output voltage. A timer/sequencer device is connected to receive as inputs thereto both such predetermined output voltage from such power supply device and an uncoupling command signal from a momentary input command for providing a pair of output signals.
