The 901-D Multiple Input Logic is designed to provide a proportional time base for operating one or more power switches and/or the sequencer of the control system. The percentage of time that the power is connected to the load is based on the level of the input signal. The input signal can be a temperature sensor, a resistance, a voltage, or a current.
- Multiple selectable inputs
- Field adjustable zero and span for all inputs
- Controls up to 12 power switches from one board
- Low voltage control, requires 24V AC power
