Chromalox 3340-4V04100000 Multi-Loop Controller

The Chromalox 3340-4V04100000 Multi-Loop Controller from Thermal Devices, an authorized Chromalox distributor. The 3340 can control up to a maximum of 8 channels in a compact 1/4 DIN package. The 1/4 DIN controller reduces panel size and panel cutouts. By increasing zone density, the 3340 can now make PID temperature control for 3 to 8 zones affordable in a multiloop form factor, aiding designers of control equipment to save labor costs, installation costs, electric panel size, and operation cost. Alarm 2 can be ordered as a Heater Break Alarm. For loads with multiple heaters this feature alarms when individual heaters fail. This provides maintenance of a process before the problem becomes critical. Temperature set point, PID constants, alarm set point, ramp to set point rate, channel used/unused for each loop can be stored in a “memory area”. The eight memory area allows for quick changes to alternate processes or products. The memory area can be selected via the front faceplate or digital inputs.
