The Series SD 1/32 DIN panel mount size single display PID temperature/process controller supports timed temperature/process control, as well as on/off timing for a variety of external devices such as pumps, fans and lamps. The unit’s set point can be programmed to control the timer set point value during the timing period, and then revert to the static set point value when the count down time has elapsed. Either or both of the controller’s outputs can be programmed to turn external devices on or off during or after the countdown time has elapsed. The controller’s display can be programmed to show countdown time, process value or set point.
