Material Composition FR-4 multilayer printed circuit board; Gold-plated backplane gold finger; Opto-coupler isolation chips; Filter resistors and capacitors; Surge protection components; Anti-static plastic panel.
Structural Features Rack plug-in card structure; Front panel with multi-channel LED status indicators; Rear gold fingers connect rack backplane bus; Anti-reverse insertion positioning notch; Model and version printed on panel.
Working Principle Field 24VDC switch signal enters the card through terminal base. The opto-coupler realizes electrical isolation between field circuit and control circuit. Hardware de-bounce circuit filters contact bounce interference. The card converts on-off status into digital value and uploads to controller via backplane bus. It monitors loop condition continuously and reports open circuit or overvoltage fault.
Installation Requirements Wear anti-static wrist strap during disassembly and assembly; Insert card vertically into rack slot and lock fixing screw; Cabinet protective ground must be complete; Separate signal cable and power cable; Verify hardware version compatibility with controller firmware.
Precautions for Use Prohibit hot swapping of module; Never connect high voltage AC signal to input channel; Check field contact and external wiring when channel fault alarm appears; Inspect terminal screw tightness periodically.
