Watlow Series 93 Control. The Watlow Series V4T was a single input, dual output PID controller that offered proven features for general purpose temperature control applications. The feature set included heat/cool PID control, closed or open loop control, a single universal input, a full range of output options, ramp to set point operation and versatile alarms. Dual displays, along with large operator control keys, and an easy-to-understand interface simplified setup as well as reducing the chance of operator errors. Optional hardware features included red or green displays, and low voltage power supply.

Watlow Series V4T met NEMA 4X standard for water and corrosion resistance. This feature made the Series V4T ideal for applications such as food processing, packaging and medical instruments where equipment needs to be cleaned frequently. The front panel could be hosed or wiped down without damage to the controller.

Control accuracy of ±0.1 percent was supported over an operating environment range of 0 to 65°C. Agency approvals included UL® and C-UL 508 recognition, NEMA 4X, along with complete CE compliance.
