Product Introduction
The ProSoft Technology ILX34-MBS485 is a dedicated communication module engineered to provide robust RS-485 and RS-422 serial connectivity for Allen-Bradley 1734 Point I/O systems and CompactLogix L1 controller architectures.
Ideal for connecting remote field devices, instruments, meters, or SCADA equipment over long distances (up to 4,000 feet / 1,219 meters), this module supports both Modbus RTU and ASCII protocols in either Master or Slave configurations. It features powerful Add-On Instructions (AOIs) for Studio 5000 / RSLogix 5000, ensuring seamless data integration and automatic project backup within the controller file.

Compliance & Standards Alignment
- Manufactured in compliance with global quality and safety standards, carrying certifications suitable for industrial automation environments.
- Built with high noise immunity and robust ESD protection (6kV contact / 8kV air discharge) to withstand harsh plant floor electromagnetic conditions.
Technical Note: The module requires a compatible 1734 Point I/O terminal base assembly. Ensure proper network biasing and 120-ohm line termination resistors are implemented at both ends of long RS-485 cable runs to prevent signal reflection errors.
Storage & Asset Preservation Guidelines
- Store the module inside its original factory ESD-shielded antistatic bag to protect internal microprocessors and transceiver chips from electrostatic discharge.
- Keep the warehouse environment clean, dry, and climate-controlled, maintaining relative humidity between 5% and 95% (non-condensing).
- Avoid mechanical heavy shocks, drops, or physical pressure on the front status LEDs and backplane connector pins.
Physical Installation Prerequisites
- Ensure that the Point I/O rack power supply and field power sources are completely isolated, de-energized, and locked out (LOTO) prior to installing or removing the module.
- Observe strict electrostatic discharge (ESD) safety protocols, including wearing a tested ground strap while handling internal electronics.
- Snap the module securely onto the designated 1734 terminal base, verifying that all mechanical locking latches and backplane pins engage properly.
Buyer’s FAQ & Logistics
Q: What Harmonized System (HS) code applies to this ProSoft communication module?
A: Industrial communication interface cards, PLC adapter modules, and data transmission equipment typically classify under HS code 8517.62 (Machines for reception, conversion and transmission or regeneration of voice, images or other data) or 8538.90. Confirm final details with your customs broker.
Q: Can the ILX34-MBS485 be used as both a Master and a Slave?
A: Yes. The serial port is software-configurable to operate as either a Modbus RTU/ASCII Master or a Slave device depending on your application requirements.
Q: Is the listed online price final for procurement?
A: Note: Price is subject to market availability, batch surplus tiers, and global shipping logistics; contact our technical sales desk for a formal, time-sensitive quotation.
