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.

Installation

4 Installation

4.1 Outdoor Enclosure Installation

1. Install or use existing outdoor NEMA-type enclosure.

2. Be sure the RS485 I/O Expansion System meets applicable grounding requirements
in the enclosure.

3. Install a 35 mm x 7.5 mm DIN rail (at least 166 mm (6.5-inch) wide) inside the
enclosure.

4. Provide external power supply: 9-30 VDC.

5. Make a hole on the bottom of the enclosure to run wires.

6. Run conduit for power and I/O cabling.

7. Feed power wiring into enclosure.

8. Terminate RS485 wiring.

Installation

4.2 RS485 I/O Expansion System Assembly

Warning: Power must be disconnected or turned off prior to attaching or removing any I/O
Modules from the system – failure to comply may cause damage hardware.

1. Securely attach the DataRail onto a 35 mm x 7.5 mm DIN rail by gently
pressing on all four (4) corner clips.

2. Secure DataRail to DIN rail by attaching an End Terminal Bracket.
a. First, hook the metal end of the Bracket to DIN rail and then snap the

other end onto the DIN rail. (Make sure to position the Bracket on the far
left of the DataRail where metal blades meet the plastic).

Installation

3. Attach RS485 I/O Expansion Module to DataRail (place it next to the Bracket

4. Attach I/O Module(s) to the system.

without any gap).
a. First, latch the top hook onto the rail, then snap-in the spring-loaded clip

into place.

a. Place Modules in any combination (do not leave gaps between Modules).

b. When using more than five (5) I/O Modules, determine maximum I/O

Module combination by using power budget calculator: http://psft.com/A7U

c. Use the 16-position switch located on the front of each I/O Module to set

the Modbus Slave ID(s). Slave ID = Switch position number + 1.
Ex: Switch ID 0 + 1 = Slave ID 1

ProSoft Technology, Inc. Page 17 of 36
June 10, 2015

Installation

5. Attach the other End Terminal Bracket to secure the Modules. (Place it next
to the last module without leaving a gap)

6. Protect any unused DataRail slots with the cover. Snap-off extra pieces and
store for future use.

7. Terminate the RS485 terminals.

Page 18 of 36 ProSoft Technology, Inc.

Installation

4.3 RS485 Daisy-Chain Diagram

1. If more I/O Modules are required, another RS485 I/O Expansion Module (Kit) set

can be deployed simply using the daisy-chain method.

2. The System holds up to 16 I/O Module Slave addresses regardless of the number

of RS485 I/O Expansion Modules deployed.

3. Each Module must be set to a unique Modbus Slave address.

Installation

4.4 Detaching Components from the DataRail

Warning: All live wiring connections and power must be safely disconnected before taking any
components off the DataRail or Wireless I/O System!

1. The End Terminal Bracket can be removed from the DIN rail by inserting the
tip of a flathead screwdriver into the removal slot. Control the direction with
the screwdriver handle to pull the latch away from the DIN rail.

2. Wireless I/O Modules can be removed from the DIN rail by inserting the tip of
a flathead screwdriver into removal slot located on the metal clip. Lift-up on
the screwdriver handle to pull the spring-loaded clip away from the DIN rail.
