Quick Detail

Description

Bently Nevada 133323-01 is a Modbus RS485 I/O Module designed for 3500 Series racks to enable data exchange between machinery protection systems and automation networks. The 133323-01 supports Modbus RTU over RS485 and Modbus/TCP over Ethernet TCP/IP, providing communication at 10 Mbps via RJ-45 10BASE-T interface conforming to IEEE 802.3.

Installed in one full-height rear slot, 133323-01 consumes 5.6 Watts typical when operating with the Modbus RS485 interface. The 133323-01 transmits rack monitored values, alarm status, and module data to PLC, DCS, and SCADA systems through configurable Modbus registers. TX/RX LEDs on 133323-01 indicate active communication with 3500 rack modules, while the OK LED confirms operational status.

Designed for industrial automation environments, 133323-01 operates from -30°C to +65°C and tolerates storage temperatures from -40°C to +85°C with 95% non-condensing humidity. By integrating 133323-01, users can transfer vibration, position, and alarm data from 3500 monitoring modules directly into plant-wide control systems using RS485 serial communication.

Applications

Application Transmit 3500 Rack Data via RS485 Network

133323-01 is installed in one full-height rear slot of the 3500 rack to transmit monitored values and alarm status through Modbus RTU over RS485. With 5.6 Watts typical power consumption, 133323-01 collects vibration, position, and alarm data from rack modules and sends it to PLC or DCS systems. The RS485 interface of 133323-01 supports multi-drop communication, allowing multiple automation devices to access rack data on the same serial bus.

Application Integrate Monitoring Data into Ethernet TCP IP Systems

133323-01 provides Ethernet communication at 10 Mbps via RJ-45 10BASE-T connection compliant with IEEE 802.3. Using Modbus/TCP protocol, 133323-01 transfers real-time rack parameters to SCADA and plant control systems. Engineers can configure Modbus registers inside 133323-01 to map vibration amplitude, shaft position, and alarm states directly to control registers.

Application Monitor Communication Status Through LED Indicators

133323-01 includes OK LED and TX RX LED indicators. The OK LED confirms that 133323-01 is powered and operating within the -30°C to +65°C temperature range, while the TX RX LED shows active communication between 133323-01 and other rack modules or external controllers.

Specifications

Competitive Advantage

Competitive Advantage Support Dual Communication Modes in One Module

133323-01 supports both serial Modbus RTU over RS485 and Modbus/TCP over Ethernet. This allows automation engineers to use 133323-01 in legacy serial networks or modern TCP IP infrastructures without additional converters.

Competitive Advantage Low Power Consumption for Full Rack Operation

With 5.6 Watts typical consumption in RS485 mode, 133323-01 minimizes load on the rack power supply. The 133323-01 enables continuous communication of all monitored values while maintaining efficient power usage in the 3500 system.

Competitive Advantage Operate in Industrial Temperature and Humidity Conditions

133323-01 operates between -30°C and +65°C and withstands storage temperatures from -40°C to +85°C with 95 percent non-condensing humidity. These parameters allow 133323-01 to function in turbine halls, compressor stations, and heavy industrial automation cabinets where environmental conditions vary.
