P4-5. Specify an acceptable value and power rating of a pull-up resistor, $R_{pu}$, to be used to connect a sinking sensor device to a PLC sinking discrete input channel (Figure P4.1). The power supply is nominally 24 volts but can range between 23 and 25 volts, depending on the current draw. The minimum \"on\" state voltage of the discrete input channel is 10 volts, and the equivalent input resistance is 1000 ohms. The maximum device sink current is 100 mA, and the minimum device output voltage is 2.0 volts.
