Functional Features 12 independent slots provide mechanical positioning and electrical connection for RX3i series modules. High-speed backplane bus realizes high-speed data exchange between CPU module and all I/O and communication modules. Gold-plated slot connectors ensure stable electrical contact under long-term cabinet vibration. Backplane power distribution traces transmit DC power from rack power supply module to every slot module. Supports hot-swap function of I/O modules for non-critical process maintenance. Rigid mechanical structure improves rack stability in industrial cabinet environment.
Application Scenarios RX3i PACSystem PLC control cabinets used in water treatment plants, material conveying systems, packaging machinery, metallurgy auxiliary control and general industrial automation projects. It works as main rack backplane for RX3i PLC, carrying CPU, power supply and multiple I/O modules for discrete and analog process control.
Performance Parameters Backplane bus maintains high-speed and low-error data transmission within full working temperature range. Gold-plated connectors keep stable contact resistance after repeated module plugging. Power distribution traces deliver rated DC power to each slot without voltage drop exceeding specified tolerance. Mechanical structure resists vibration impact from industrial cabinet environment.
Material Composition Main substrate adopts multi-layer flame-retardant glass-fiber epoxy printed circuit board. Flame-retardant reinforced plastic mechanical frame. Gold-plated copper alloy multi-pin slot connectors. Metal fixing brackets for DIN rail installation.
Structural Features Long strip-shaped rack structure with 12 module slots arranged in linear sequence. Each slot is equipped with independent gold-plated connector and module guide rails. Spring mechanical latch positions each plug-in module. Metal mounting buckles on back side for DIN rail fixing inside control cabinet. Internal PCB traces form high-speed backplane communication bus and power distribution circuit.
Working Principle Rack power supply module inputs DC power to backplane power distribution traces. Power distributes to each slot connector for supplying power to plug-in modules. RX3i CPU module communicates with all I/O and communication modules via high-speed backplane bus traces on PCB substrate. Backplane connectors complete electrical connection between each module internal circuit and shared rack bus. All modules share the same backplane bus to exchange control commands, process data and diagnostic information.
Installation Requirements Mount the backplane on standard DIN rail inside control cabinet and lock metal mounting buckles. Keep horizontal installation posture and reserve sufficient air circulation space above and below rack. Separate PLC rack wiring from high-voltage power cables to reduce electromagnetic interference. Insert RX3i modules into corresponding slots along guide rails and lock each module latch.
Precautions for Use Cut off rack power supply before installing or removing CPU and power supply modules. Take anti-static measures during module installation and handling. Keep slot gold-plated connectors clean without dust, moisture and metal debris. Do not apply overvoltage to backplane circuit. Do not cut or modify internal PCB traces of backplane.
