Digital I/O Extension

Overview

The Digital I/O extension feature connects a digital input signal to digital output(s)/relay(s) and/or a TCP/IP application over an IP network. Therefore, when the state of the digital input changes, you can also change the state of the digital output or relay channel or output serial signal pin on a local I/O channel(s), other IOLAN I/O channels, other IOLAN serial signal pins, or the data can be sent to an application(s).

For example, when the door opens (I/O digital input sensor) in a factory, a light goes on in the reception office (remote IOLAN relay channel), and the door open/close is logged by an application on a remote host.
