Quick Detail

Description

The 136188-02 Ethernet/RS485 Modbus I/O Module is a communication gateway for industrial automation and machinery monitoring systems. The 136188-02 installs in a single full-height rear slot of a 3500 rack, operating from −30 °C to +65 °C and storing from −40 °C to +85 °C with 95% non-condensing humidity. Typical power consumption is 5.0 W with RS232/RS422 I/O and 5.6 W with RS485 I/O.

The 136188-02 supports Ethernet 10 Mbps links (RJ-45) and serial communication via RS232, RS422, or RS485. It communicates with 3500 Configuration Software and Data Acquisition Software using BNCHost Protocol, Modbus/TCP, and standard Modicon Modbus RTU. OK and TX/RX LEDs indicate operational status and communication activity.

In automation systems, the 136188-02 enables real-time transfer of monitored values, alarms, and status from 3500 racks to control systems, ensuring integration of turbine, compressor, or pump data for process control, trending, and diagnostics. Its configurable Modbus register utility allows customized mapping for seamless PLC and SCADA integration.

Applications

Transfer 3500 rack data to PLC and SCADA systems

The 136188-02 Ethernet/RS485 Modbus I/O Module communicates monitored values, alarms, and status from up to 14 modules in a 3500 rack using RS232, RS422, RS485, and 10 Mbps Ethernet TCP/IP. With power consumption of 5.0 W (RS232/RS422) or 5.6 W (RS485), the 136188-02 transmits real-time data to PLCs and SCADA systems without overloading the rack power budget.

Enable remote configuration and data acquisition

Using BNCHost Protocol over Ethernet, the 136188-02 allows remote configuration and acquisition from 3500 Configuration Software. Operating over a temperature range of −30 °C to +65 °C and storing up to −40 °C to +85 °C, the 136188-02 maintains communications even in high-temperature control cabinets.

Map Modbus registers for custom control applications

The configurable Modbus register utility in the 136188-02 allows operators to assign up to 256 monitored values to specific Modbus addresses. This enables precise integration of turbine, compressor, and pump data into automation control loops.

Monitor communication and operational status

The 136188-02 provides OK and TX/RX LEDs, reporting operational status and data transmission activity. The module maintains 95% non-condensing humidity tolerance, ensuring accurate indication in industrial environments.

Specifications

Competitive Advantage

Multi-protocol communication support

The 136188-02 supports Modbus RTU (RS232/RS422/RS485), Modbus/TCP (Ethernet), and BNCHost Protocol. With 10 Mbps Ethernet bandwidth, the 136188-02 can handle data from 14 modules and over 256 monitored values simultaneously.

Low power consumption for high-density racks

The 136188-02 consumes only 5.0–5.6 W, allowing multiple communication modules in a single 3500 rack without exceeding the 3500 power supply limits.

Wide operational temperature range

Rated −30 °C to +65 °C and storage −40 °C to +85 °C, the 136188-02 ensures continuous automation communication even in industrial environments with fluctuating temperatures.

Full-height rear slot integration for modular racks

The 136188-02 installs in one full-height rear slot and interfaces with all 3500 monitored values. This allows engineers to integrate it into existing racks without relocating other modules, maintaining rack efficiency.

Real-time Ethernet and serial data transfer

The 136188-02 transmits monitored values, alarms, and status over RJ-45 Ethernet or RS485/RS422 serial links with low latency. Its 10 Mbps Ethernet link ensures rapid update of process control systems, supporting real-time automation decisions.
