Analog Setpoint Temperature Controller from Dwyer Instruments

The Dwyer Series 1400 Temperature Controller is a reliable, accurate and ultra-low cost analog control or alarm in a compact 1/16 DIN case. LED status and deviation indication, analog setpoint indicator and dual °F/°C scale are standard features. Optional auxiliary alarm available at modest cost. Inputs include J and K type thermocouples or RTDs. Control outputs are available as either On/Off or Time Proportioning Relay, SSR or 5VDC Logic reverse acting (heating). Alarm outputs (auxiliary or main) are field configurable reverse acting (heating) or direct acting (cooling) and are easily adjusted for either automatic or manual reset to provide independent high or low system protection. Electronics are easily replaceable via removable front panel (just pull out - no wiring changes). Front panel meets NEMA-2 and NEMA-12.

Series 1400

PHYSICAL DATA
Accuracy: ±2% full scale
Input Impedance: Thermocouple (3 megohms min.) RTD current (500 µA max.)
Deviation Indicator: LEDs indicate process value deviation from setpoint of greater than 1.5% full scale.
Thermocouple Break Protection: Upscale standard Sensor Break or Short
Protection: Standard for RTD input.
Supply Voltage: 100 to 240 VAC, 50-400 Hz.
Operating Range: +14 to 130°F (-10 to 55°C); storage -13 to 149°F (-25 to 65°C);
