CPU 1217C Differential Input (DI) detail and application example
Notes
• Each differential DI is biased "OFF" when terminal block screws are open-circuit.
• Built-in DI Termination and Bias = 100 Ω equivalent impedance.
• Built-in DI Termination and Bias resistors limit the continuous common mode voltage
range. See electrical specifications for detail.
