Dwyer TSF-4011-MDF Thermocouple Limit Control is designed to operate in ambient temperatures ranging from 32 to 150°F (0 to 65°C) and can be stored in temperatures between -4 to 176°F (-20 to 80°C). With an accuracy of ±1% FS and a power requirement of 115 VAC, 230 VAC, 12 VAC/VDC or 24 VAC/VDC, this control ensures precise temperature regulation. It features a 3-digit, red display for easy monitoring, and a nonvolatile memory for storing settings. The control operates with Type J, K or S thermocouples and offers a probe range of 32 to 999°F (0 to 700°C) for Type J thermocouples and 32 to 999°F (0 to 999°C) for Type K or S thermocouples. The SPDT relay, with a rating of 16 A @ 240 VAC resistive, provides reliable output. With a front panel rating of IP64 (NEMA 3R), this control offers durability and protection against dust and water. It also has ON/OFF and manual/automatic reset control options. The Dwyer TSF-4011-MDF is a feature-rich thermocouple limit control that is suitable for a variety of applications.
