 - Installation Guide

GENERAL DESCRIPTION

The DA 8DI/8RO module is designed for use with the DA70 

controllers, that can support up to 10 I/O modules simultaneously.  

This module features 8 Digital Inputs and 8 Relay Outputs that 

can be used to monitor contact or sensor inputs and actuate 

relays, solenoids, PLC inputs, etc. 

The inputs accept standard DC inputs or contact closures, and 

are configured for Sink/Source signals via software switches. 

Additionally, each input has a switch selectable input filter that 

can be used to prevent contact bounce. Each input may also be 

software configured as a high-active or low-active input.

The module is available with relay outputs that are capable of 

switching up to one amp each. For applications requiring large 

loads to be controlled, several DIN rail mount relays are available. 

The modules connect and communicate via proprietary 

backplane to the DA host device. The DA host device, equipped 

with serial ports as well as an Ethernet port(s), allows the system 

to share data with PCs, PLCs, and SCADA systems.

Internal power management circuits allow the module to be 

replaced while power is applied, which reduces downtime in the 

event of a module failure. All configuration information is stored 

locally within the module, as well as in the Host, so replacement 

modules do not need to be configured.

CONFIGURATION

The DA 8DI/8RO modules are configured with Windows

®

 

compatible Crimson

®

 software. The software is an easy to use, 

graphical interface which provides a means of configuration and 

commissioning of new systems, as well as routine module 

re-calibration.
