Preface

1 Preface

Thank you for choosing the RS485 I/O Expansion System. This I/O expansion solution is designed for use with any Modbus RS485 Master device as a standalone system. This System follows the Modbus Application Protocol Specification, v1.1b3, for Data Encoding with values represented in Big-Endian format or MSB first (word order).

Digital/Discrete, Analog 4-20 mA, or Analog 0-10 V are available for use with the RS485 I/O Expansion System. This System provides fast, accurate, reliable I/O's and requires no software programming, making it extremely easy and quick to use.

To interface with a RS485 Master device, the System utilizes a RS485 I/O Expansion Module that transfers I/O signals between Modbus Master and connected I/O Modules. The RS485 Module also distributes power to the I/O Modules allowing for single point power termination.

This document is designed to guide you through setting up the system by familiarizing you with the hardware, installation, wiring, and overall system management.

Preface

1.1 Compliances

 Changes or modifications not expressly approved by the manufacturer may

void the user’s authority to operate the equipment.

Warning: Ensure system installation meets applicable state and national electrical code requirements. The installation of the system should only be performed by a qualified installer or a factory representative.

Warning: To prevent ignition of flammable or combustible atmospheres, disconnect power before servicing.

Caution: The RS485 I/O Expansion System must be installed within an enclosure that requires a tool to access. This is to prevent inadvertent disconnection of any of the power wiring, signal wiring or communication cables.

Caution: EXPLOSION HAZARD. Do not disconnect equipment unless power has been switched off or the area is known to be non-hazardous.

Caution: EXPLOSION HAZARD. Do not remove or replace fuse when energized.

Note: This equipment is designed for use in Class I, Division 2 (Zone 2) or non-hazardous

locations only.

System Overview

2 System Overview

2.1 Highlights

 Local I/O expansion solution for use with any RS485 Modbus Master device.  System utilizes a pass-through RS485 Interface/Module for transferring I/O signals

between Modbus Master and connected I/O Modules

 One RS485 Expansion I/O Module supports multiple Wireless I/O Modules.

System can support up to sixteen (16) Digital Modules System can support up to eight (8) 0-10 V Modules System can support up to five (5) 4-20 mA Modules

When adding more than five (5) I/O Modules and mixing different I/O

Modules, please determine maximum allowable I/O Module combination per system by utilizing the power budget calculator: http://psft.com/A7U

 Supports Digital, 0-10 V, and 4-20 mA Modules in any combination.  Each I/O Module provides field isolated inputs and outputs.  Easy to use: no software configuration required.  System attaches onto 35 mm x 7.5 mm DIN rail with easy, clip-on mounting system.  Reduced wire clutter: single power termination.  Wiring label provided on each Module for quick reference.  All Modules are color-coded for quick reference and identification.  The same I/O Modules can also be used for wireless application with Wireless I/O

Radio Kit.

 Reduced wire clutter: single power termination.  Quick wiring reference label provided on each Module.  Wireless I/O System can support multiple I/O Modules.

System can support up to sixteen (16) Digital Modules max.

System can support up to eight (8) 0-10 V Modules max.

System can support up to five (5) 4-20 mA Modules max.

Warning: When adding more than five (5) I/O Modules and mixing different I/O Module combinations, please determine the maximum allowable I/O Module combination per system by

utilizing the power budget calculator. See http://psft.com/A7U
