摘要： A remote control circuit breaker and contactor system having at least one I/O circuit functioning as an interface between a central processing unit and a plurality of up to 32 devices such as remote circuit breakers for each I/O circuit, each remote circuit breaker having an individual electronic circuit which receives commands from the I/O circuit to turn the breaker or contactor on or off or hold and also senses the state of the breaker contacts and the control line and upon request sends back status codes which are stored in the memory in the I/O circuit to be read when desired by the central processing unit. Four-state status information is provided including open, closed, tripped and problem (low voltage, open or shorted control line). Contact state is determined by directly measuring the contact resistance in single break contacts (or solid state device contactors) or the contact voltage in double-break contacts. The I/O circuit provides noise rejection using measured noise as a threshold to minimize the effect of electrical noise on the status communication signals coming from the remote breaker electronic circuit. In the event electrical noise on the control line or the like causes rapid turn-on and turn-off of the remote breaker, a rapid cycle inhibit circuit for a timed interval stops such cycling of the remote breaker after a predetermined number thereof to prevent damage to the remote device due to overheating. The remote breaker electronic circuit affords manual control of the breakers or contactors and trip indication of the breakers in addition to computer control through the I/O circuit. The system uses tri-state communication circuitry which includes a hold command and prevents unwanted state changes during losses of power or when a control line shorts to ground or opens.

摘要： A remotely changeable thermostat for a refrigeration or air conditioning system and method and system employing same. The thermostat has a fluid filled capsule with a diaphragm movably responsive to fluid expansion and contraction for actuating, via lever means, a compressor power switch. The capsule senses temperature via a fluid filled capillary. A separate remote user activated switch energizes an electrical actuator for moving the fulcrum of the lever means to change the sensed temperature of the evaporator at which the power switch is actuated. The user activates a remote switch to energize an electrical heater coil for heating a bimetal strip which moves the fulcrum for the lever means between a high or low temperature setting for compressor power switch actuation in response to user opening or closing the remote heater switch.

摘要： A resistance wire sensing overcurrent protection module (CSM) for an electrical supply circuit (SC) having a hot temperature sensing diode (32) mounted at the center portion (8c) of an M-shaped resistance wire (8) connected in the supply circuit and an ambient temperature sensing diode (20) mounted on a substrate (18) supported between the supply terminals (4a-b, 6a-b), both diodes being connected to respective pairs of terminals (12a-b, 10a-b) mounted on a header (18) along with the supply terminals. A cover (46) is mounted on the header and filled with glass micro-balloons (48) to isolate thermally the two diodes. A constant current circuit (49) supplies constant current to the two diodes which operate a differential amplifier (52) having an output proportional to the temperature difference as a measure of supply current. This output trips a Schmitt trigger comparator (54) when the supply current rises to an overload value.
