Using GPIO interface

Contents of this chapter

This chapter describes the general purpose inputs and outputs used in the
MACHsense-R.

GPIO interface overview

The MACHsense-R has eight general-purpose inputs/outputs: 4 inputs and 4
outputs. All inputs and outputs are isolated from the logic of using optocouplers.
• GPO interface-requires external voltage source and can support voltage 5 V
and 24 V.
For more information, see
• GPI interface-supports input voltage up to 24 V and pulse rate of 100Hz.
For more information, see

GPO connection

To connect the GPO terminal inside MACHsense-R, do the below steps:
1. Pierce the rubber membrane using a screwdriver to push through a serial cable.
For instructions, see
2. Push cables through the tight openings in the cable plate, through the gasket
and then strip down the cables.
3. Strip down the cables to 10 cm and crimp the ferrules on each wire using an
appropriate crimping tool. Leave 2 cm of the cable screen.
