The CAL Controls 3300 Series temperature controller is a 1/32 DIN autotuning PID controller that comes standard with two outputs: solid state driver to switch a remote solid state relay (5Vdc +0/-15%, 15mA, non-isolated) and Relay form A/SPST contacts (2A/250 VAC resistive load). CAL Controls 3300 Series controllers are powered by a 24V AC/DC or a 100-240VAC power supply.
