Relativehumidity, output status, and error messaging can be viewed onthe bright green LED. The switch features 9 user defined para-meters including setpoint, hysteresis, control type, cycle time,and probe adjustment. Access to programming parameters canbe locked for security purposes using the password protectionfeature. The Series HS includes a fitting clip for panel mount-ing, gasket, rear terminal cover, and instruction manual.MODELS3[76]1-11/32[34]2-3/8[60]1-7/64[28]SPECIFICATIONSRelative Humidity Range: 0 to 100% RH.Input: 0 to 3V, 0 to 1V or 4-20 mA (depending on model) humidi-ty probe not included.
