Dwyer TCS-J is a thermocouple temperature switch with a temperature range of 32 to 158°F (0 to 70°C) for ambient use and -4 to 176°F (-20 to 80°C) for storage. It has an accuracy of ±1% FS, power requirement options of 115 VAC, 230 VAC, 12 VAC/VDC, or 24 VAC/VDC, and a resolution of 1°. It features a 3-digit red display, a SPDT relay output rated at 16 A @ 240 VAC resistive, and supports Type J or K thermocouple input. The switch also has nonvolatile memory, an IP64 front panel rating, and a probe range of 32 to 999°F (0 to 700°C) for Type J thermocouple and 32 to 999°F (0 to 999°C) for Type K or S thermocouples. It operates on an ON/OFF control type and has a 1 HP horsepower rating.
