Ranco 2 Stage Digital Controller with Alarm, Cyclic Timer, and Process Timer

Applied for heating, it uses a type J thermocouple* as a sensor for the temperature range from -50° C to 600° C. It has two control outputs for temperature and an internal audible alarm (buzzer). The first output uses a cyclic preheating mode and the second output may be configured to work as an alarm, timer (cyclic timer) or indicator of process completion. It features a timer that operates in different modes, driven by digital inputs, which indicates the end of the time of one or two processes. It also has five configurable recipes, allowing to quickly change the values of the setpoint (desired temperature) and hysteresis (control differential) of the first stage and the process time.
