Description
TOSHIBA UTNH23A
Technical Specifications: Model: UTNH23A Network standard: TC-net 100 industrial control network Transmission medium: Optical fiber Function: Optical shared hub, signal repeater and distribution Power supply: 24VDC Operating temperature: 0℃ to +60℃ Storage temperature: -20℃ to +70℃ Relative humidity: 5% to 95%, non-condensing Protection class: IP20 Mounting: Rack plug-in module for Toshiba V-series controller rack
Functional Features: Realize TC-net 100 optical signal receiving, repeating and distribution. Convert electrical control network signal to optical signal for long-distance transmission. High anti-interference performance via fiber optical transmission, eliminate ground loop interference. Support multi-station connection of Toshiba V-series controllers on TC-net 100 network. Built-in network signal diagnosis and link fault detection function. Front panel LED indicators for optical link and module fault status. Support redundant network configuration for high reliability control system.
Application Scenarios: Power plant Toshiba V-series controller network interconnection, thermal power plant distributed control system fiber network, heavy industry factory multi-station controller communication, water treatment large-scale distributed control network, metallurgy plant furnace control system fiber communication.
Performance Parameters: Stable optical signal repeating and distribution for TC-net 100 network. High electromagnetic noise immunity for fiber transmission. Fast link fault detection and status reporting. Continuous stable operation for 24/7 industrial control system.
Material Composition: FR4 printed circuit board. Optical transceiver components. Signal shaping and network processing chips. Flame retardant plastic front panel with LED indicators. Gold plated backplane connector for rack bus and power supply. Optical fiber connector interface components.
Structural Features: Toshiba V-series rack plug-in module design. Front panel with LED indicators for power, optical link and fault status. Optical fiber port for connecting field optical cables. Internal circuit separates optical receiving/transmitting circuit and backplane electrical circuit. Edge connector connects with rack backplane for 24VDC power and local bus communication.
Working Principle: 24VDC power supplies UTNH23A module from rack backplane. Electrical TC-net 100 network signal from controller enters module. The module converts electrical signal into optical signal and distributes optical signal to other connected control stations via optical fiber. Optical signal from remote stations is received and converted back to electrical signal, then transmitted to local controller. Built-in diagnostic circuit monitors optical link quality continuously and triggers fault indication when fiber break or link loss occurs.
Installation Requirements: Insert UTNH23A module to designated slot of Toshiba V-series controller rack. Connect matched optical fiber cables to optical port of module. Route optical fiber cable separately from power cables. Install rack in ventilated IP20 control cabinet. Complete protective earth connection for rack chassis. Clean optical fiber connector before installation.
Usage Notes: Do not touch optical fiber core directly, avoid contamination and scratch. Check optical link LED indicator after fiber connection. Cut rack power supply before removing module. Inspect optical connector cleanliness regularly during maintenance. Use specified type of optical fiber matching TC-net100 network.
