Series 120 employs a UL Class 2 low voltage sensor circuit. Standard models have 115/230 VAC field selectable input, up to 20 A SPST relay output, on-off control mode, and choice of NTC thermistors, platinum RTD or thermocouple sensors. Overlapping setpoint ranges from 0 to 2,000°F (-17 to 1,093°C) depending on sensor type. Accuracy is ±1°F over an ambient operating temperature of 32 to 158°F (0 to 70°C). Optional control configurations include 24 VAC input voltage; fixed, remote or local setpoint adjustments; custom setpoint ranges and DC SSR driver output.
