Hybrid sequential Step Controller The D46 hybrid sequential step controller is designed to be used where fine control accuracy is required and the heater capacity is too high to be handled economically by "FULL SCR". With a combination of a smaller SCR and a step controller, bot...

Pneumatic-electronic transducer. The P37 is a Pneumatic-electronic transducer that converts a 2-13 psi input into a proportional Pulse or 0-10VDC output and therefore replaces both the P35 and P36. For ease of use the board is programmed for 3-8 psi Pulse output selectable from ...

The D21-T electronic controller has been designed to take full advantage of our patented Air-Flow Sensor which modulates the heater’s capacity according to the quantity of air flowing through the heater by responding to the radiant heat of the elements even at very low CFMs. With...
