Abstract
Components and devices are provided for controlling and monitoring a machine or process using an automation controller that may be capable of receiving inputs from a digital source, an analog source, or a thermistor source. In one embodiment, an automation controller may include first, second, and third input terminals. The first and second input terminals may receive input signals from analog and digital sensors, and the second and third terminals may receive input signals from a thermistor.
Claims20
An automation component comprising:
- a first input terminal configured to receive an input from an analog sensor or a digital sensor;
- a second input terminal configured to receive an input from the analog sensor, the digital sensor or a thermistor;
- and
- a third input terminal configured to receive an input from the thermistor.
An automation controller comprising:
- first, second and third input terminals, the first and second input terminals being configured to receive input signals from analog and digital sensors, and the second and third terminals being configured to receive input signals from a thermistor.
An automation component comprising:
- a first input terminal configured to receive an input from an analog sensor or a digital sensor;
- a second input terminal configured to receive an input from the analog sensor, the digital sensor or a thermistor;
- a resistor coupled across the first and second input terminals;
- a third input terminal configured to receive an input from the thermistor;
- and
- a power supply coupled to the third input terminal and configured to provide power to the thermistor when coupled to the third input terminal.
