OpenNet Multi Function IO

The OpenNET 6000 multi-function expansion cards are telemetry input/output interface cards designed to expand the capabilities of the OpenNET MAX programmable controller.

Six types of card are available, offering different combinations of digital and analogue inputs and outputs, up to a maximum of 16 channels per card.

The digital inputs are optically isolated from the rest of the system. However they may still be used with simple volt-free contacts pulling the inputs to 0V because they are pulled up to 12V by an isolated supply that is common to all inputs.

The digital outputs are implemented by changeover relays, and a single jumper selection allows use in either Normally Open or Normally Closed configurations, independently for each channel.

Output contacts are isolated from each other and the rest of the system.

Each input and output channel uses two separate two-part screw terminals. Each input channel includes an LED indicator that is illuminated when the input is closed. Each output channel includes an LED indicator that is illuminated when the relay is energised.

The analogue inputs and outputs can be configured to operate as 0 to 5V or 4 to 20mA current loop, have a high resolution (10 bits) and high accuracy which can be calibrated.

All cards have an address for communications with the OpenNET Max and the same form factor, enabling cards to be stacked together in a system.

  • Digital and analogue inputs and outputs
  • Six combinations
  • Total of 16 inputs and outputs
  • LED diagnostic indicators
  • Expands the capabilities of OpenNET Max programmable controller
  • Compatible with the OpenNET range of wireless telemetry devices
