    The temperature sensors and humidity sensors may need up to 12 V dc and 24 V ac as a power source. Most of the valve actuators and damper motors need a power source of 24 V ac.
    MicroCel provides a Base Unit Board with interfaces to a space sensor, four triac outputs (to drive one or two damper actuators ), input/output boards, (C-NAP bus, and 24V ac power source. Various W7620 models support floating electric or proportioning V dc damper actuators for pressure dependent or independent �
    Integral electric-to-pneumatic transducers are furnished when required to drive pneumatic actuators . Outputs: � Digital triac, 24V ac , for modulating damper and modulating valve control (floating control) � Digital relay, spdt contacts � Analog modulating, 0 to 10V dc � Pneumatic modulating, 3 to 15 psi (20 to 105 kPa) � LED drive �
    To prevent reduced operating life of the ML6161B Damper Actuator , do not use it for two-position control. ML6161B: Series 60 floating (spst) ML7161A: Modulating, 2 to 10 V dc or 4 to 20 mA NOTE: Actuators maintain last position when the power or control signal is removed. Input Voltage: 24 V ac +20%, -30%; 50/60 Hz Power Consumption, no power consumption when stopped: ML6161B: 2.1 VA maximum ML7161A: 4.8 VA maximum .
