Programmable stepper motor controller provides a digital monostable circuit, which generates a control signal. The control signal indicates a field coil within a motor, which is to be turned on or off. Two registers are provided within the digital monostable to store values that indicates a fixed off time and a minimum on time. These registers are loaded with selected values by a microprocessor. The stored values are loaded into a counter. The values in the off time and minimum on time registers are changed to suit operating conditions of the system. It is operated in open loop mode.
Programmable temperature transmitters provide an installation ready solution for temperature monitoring applications. It increases measurement accuracy and reliability over sensors wired direct. It accepts two and three wire point sensor inputs. It reduces overall installed costs compared to wiring sensors direct.
Programmable Welding Controllers are used for controlling a welding machine. The controller includes a central processing unit containing a stored control program that is connected to a memory that operates both the welding operation of the machine as well as the operation of the machine. The controller receives inputs from the machine in its various operational states as well as a data entry and display unit and a current monitor of the welding operation that generates outputs through a heat controlled output to activate a firing circuit to control the welding operation.
