HL-69158NP-0

The Johnson Controls?é?« HL-69158NP is a multi-function device that can function as a high limit or proportional override humidity controller, as stand-alone proportional controller, or a stand-alone two-position controller. As a high limit or proportional override controller, it limits duct humidity by comparing a controller?ó?é¼?äós request for humidification with the humidity present in a duct. The HL-69158NP proportionately reduces its output signal to the humidification equipment as duct Relative Humidity (RH) approaches a user-defined setpoint. As a result, the HL-69158NP provides more accurate control of duct humidity and reduces condensation. As a stand-alone controller, it can provide a proportional 0 VDC to 10 VDC or 0 mA to 20 mA output based on its own setpoint, or two-position Single-Pole, Single-Throw (SPST) Normally Open (N.O.) output. The HL-69158NP also includes an integral temperature sensor, which adds to the product's versatility.
