  • 8 Individually Selectable Digital Inputs or Outputs (optically isolated)

The Di80 is a digital I/O controller that provides 8 channels of optically isolated inputs or optically isolated transistor outputs. Each I/O channel has an input and output circuit wired in parallel. Each channel is software configured to be an input or output without the use of hardware jumpers. Jumpers are available to disconnect the input circuitry for controlling low-current loads. Di80 modules are protected from reverse power supply wiring, over-voltages, and transients, and other common events, which can damage unprotected circuits.

When used as an output, each channel can drive up to 1A at 40Vdc. The outputs are open-collector/emitter so they can be used as source-drive or sink-drive. An external\ power supply is used which can be different voltage than the node’s power supply.

When used as an input, each channel requires 5 mA of current to drive the inputs at 24V. The inputs work with multiple types of sensors such as closed contact/open-collector (sink-driving) sensors or open-emitter (source-driving) type sensors.
