UNIVERSAL RESISTANCE TRANSDUCER
RES-1E SERIES
DESCRIPTION
The RES-1E Series universal resistance transducer provides
a precision resistance output for DDC control of electric
actuators or other electronic devices that operate from a
variable resistive circuit. Various selectable analog and
pulse-width modulated (PWM) inputs are available, and the
transducer may be powered from 24 VAC or 24 VDC. The
RES-1E is furnished with snap-track for easy mounting.
FEATURES
• Ideal for controlling electric actuators
• Replaces potentiometer or temperature sensor in
boiler/chiller reset circuits
• 0-20 mA, 4-20 mA, 0-5V, 1-5V, 0-10V, 2-10V, 0-15V, 3-15
VDC or PWM input signals, DIP switch selectable
• AC/DC powered
• Replaces motorized slide-wire potentiometer controller
• 0-135, 0-270, 0-500, and 0-1000 standard outputs,
custom ranges available
• Snap-track mounting
• Failsafe mode and signal loss feature
• LED indication
OPERATION
The RES-1E simulates a three-wire potentiometer output
proportional to an analog or PWM input signal. The resistance
between output terminals B and R increases (W and R
decreases) as the input signal increases. The resistance
between output terminals B and R decreases (W and R
increases) as the input signal decreases. When 24V power
is interrupted at the RES-1E power terminals, the failsafe
mode internally connects the output terminals to the fallback
pot terminals, allowing an alternate back-up controller or
potentiometer to be used for control.
