The control mode options include factory selected combinations of ON/ OFF, time proportioning, PI using manual reset and full PID. Input for the Series 160 is a relative humidity/ temperature sensor. Features include mechanical relay outputs, remote setpot, optional remote digital displays, and various cable lengths to accommodate remote sensor location. The Series 160 is also available as a RH/Temperature signal conditioner only, that can be interfaced to other Watlow controls. Specifications Control Mode Humidity - • ON/OFF. • Hysteresis, fixed: 5% RH. • Proportional control. • Proportional band adjustable: Typically 25%RH ±5%. • Cycle time, fixed: Typically 6 seconds ±2 seconds. Temperature - • PID: Proportional with auto reset and rate (integral and derivative). • Proportional band adjustable: Typically 2 to 25°F/ 1.1 to 14°C. • Reset (integral)adjustable: Typically 0.05 to 0.5 repeats per minute. • Rate (derivative) adjustable: Typically 0 to 2 minutes per repeat. • Cycle time adjustable: Typically 10 to 60 seconds. • PI using manual reset. • Proportional band adjustable: 2 to 25°F/1.1 to 14°C. • Manual reset adjustable: ±100% of proportional band • Cycle time adjustable: Typically 10 to 60 seconds. Signal Conditioner Only Linear signal output - • Temperature: 0-5VDC 35 to 170°F/1.7 to 77°C • Humidity: 0-5VDC 30 to 95% RH Operator Interface Setpot Assemblies. • Temperature setpot with calibrated °F/°C dial scale, remote mounted. • Humidity setpot with calibrated %RH dial scale, remote mounted. Display Assemblies. • Auxiliary humidity and temperature displays, remote mounted. • LED load indicator lights. Input • Humidity (bulk polymer) sensor. 30 to 95% RH. • Temperature, thin film RTD sensor. 35 to 170°F/1.7 to 77°C. 2 WATLOW Series 160 User's Manual Output Humidity - • Electromechanical relay, Form C, 6A @ 115/230VAC 6A @ 28VDC, 1/8 hp. @115VAC, 125VA @115VAC.^ Temperature - ™ • Electromechanical relay, Form C, 6A @ 115/230VAC 6A @ 28VDC, 1/8 hp. @115VAC.125VA @ 115VAC. Accuracy Humidity - ±2.5% RH accuracy, factory calibration, standard, non-interchangeable sensor referenced at 77°F/25°C. ±10% RH accuracy, factory calibration, interchangeable sensor referenced at 77°F/25°C. Ambient rejection: <0.17% RH/°F/<0.30% RH/°C rise in ambient. Sensor cable lead rejection: No affect over range of allowable lead lengths. Temperature - Control Accuracy: ± 2.7°F/1,5°C when the control is at 77°F/25°C, the sensor is within the temperature range. Temperature range: 35 to 170°F/1.7 to 77°C. Ambient rejection: <0.10 degree per degree rise in ambient. Sensor lead resistance rejection: No affect over range of allowable lead lengths. Independent sensor cable lead length. Terminals 1/4" quick connect terminals. Power 120 or 208-240VAC +10%, -15%. User selectable. 24VAC +10%, -15%. Operating Environment Control range: 32 to 140°F/0 to 60°C. Relative Humidity: 0 to 95%RH, non-condensing. Exposing any RH sensor to contaminants and/or continuous extreme environments, may cause accuracy degradation. The Watlow sensor, while not totally immune, exhibits superior performance as indicated in tests conducted. Contact the factory for details.
