Watlow's Series SD 1/32 DIN panel-mount-size single-display PID temperature/process controller has an optional countdown timer that supports timed temperature/process control, as well as on/off timing for a variety of external devices such as pumps, fans and lamps.
The Series SD's set point can be programmed for a specified time period, and will revert to the static set point value when the count down time has elapsed. The controller's outputs can be programmed to turn external devices on or off during or after the countdown time has elapsed, and several user-selectable front panel display options allow users to tailor control information to their needs. The controller's display can be programmed to show countdown time, process value or set point.
The Series SD includes a universal sensor input, and can be programmed for heat or cool temperature control.
