Introduction

There is a line of IOLANs that can control/monitor the following types

of I/O:

z Analog Input

z Digital Input/Output

z Relay Output

z Temperature Input

Some of the models are I/O combinations and some of the models

support one I/O type.

Technical Specifications

Digital I/O

z 2 or 4 channels depending on model

z software selectable as inputs or outputs

z optical isolation of 2000V rms

Digital Input

z Dry Contact: Logic 0 = open. Logic 1 = close to GND

z Wet Contact: Logic 0 = 0-3V. Logic 1 = 10V-30V

Digital Output

z Open collector to 30V (source, sink or both)

z 200mA max load

z Digital out (DO) or pulse mode

Relay
