Technical Specifications
Power supply: 24V DC. Speed range: 0 to 15000rpm. Output: analog control + relay contacts. Communication: EtherNet/IP, Modbus TCP/IP. Control accuracy: ±0.05%. Operating temperature range: -40°C to +85°C.
Functional Features
Built-in Ethernet enables remote configuration and monitoring. Supports multiple unit parallel control via network. Web server interface for browser-based access. Full speed control and protection feature set. Data logging and fault history upload.
Application Scenarios
It applies to distributed power generation stations, multi-unit plant control, remote pump stations, networked compressor control and SCADA-integrated engine control systems.
Performance Parameters
Speed accuracy: ±0.05%. Communication response: <200ms. Parallel load sharing accuracy: ±2%. Operating temperature range: -40°C to +85°C.
Material Composition
Housing: powder-coated aluminum alloy. PCB: FR-4 with conformal coating. Ethernet connector: shielded RJ45. Terminals: copper alloy with tin plating.
Structural Characteristics
It features DIN rail mountable housing, front panel status LEDs, RJ45 Ethernet port, terminal block connections, and integrated communication processor.
Working Principle
It performs closed-loop speed control using the same proven PID algorithm as the 2301A, while an integrated network processor handles Ethernet communication, allowing remote setpoint adjustment, data monitoring and configuration from host systems over the network.
Installation Requirements
Mount on 35mm DIN rail. Connect speed sensor, actuator and power wiring. Plug in shielded Ethernet cable. Configure IP address via DIP switch or software. Set control parameters via web interface or configuration tool.
