The Sumatron Model 100C Demand Controller is designed to accept 3-wire KYZ pulses (form C contact transitions) or 2 wire pulses (form A contact transition) on a single input channel and provide peak fixed and sliding window demand, present demand, and total count on an eight digit LCD display. Additionally, the Model 100C can provide an output relay actuation anytime the demand set point is met or exceeded.
