Material Composition: Die-cast aluminum alloy housing with anodized finish; FR-4 glass-epoxy PCB; gold-plated copper-alloy connector pins; silicone rubber O-ring seals.
Structural Features: Single-slot width per IC3600 standard; front panel carries 16 input terminals and 16 status LEDs; rear side has bus connector and serial communication port; top side has binary address DIP switch.
Functional Features: Per-channel optoelectronic isolation; supports source-type (sourcing) or sink-type (sinking) input via jumper setting; channel status LEDs for field diagnostics; supports online (hot) replacement.
Working Principle: Field 24 VDC discrete signals enter the module via the input terminals, pass through optocouplers for electrical isolation, and are latched internally. The CPU polls each channel’s status via the RS-485 serial bus, completing the digital acquisition cycle.
Application Scenarios: Discrete and process control applications within GE Fanuc 90-30 / 90-70 PLC systems across manufacturing, energy, and infrastructure automation.
Installation Requirements: Install in a 90-30 / 90-70 PLC rack slot. Set the address via the DIP switch. Wire field devices to the front-panel terminal block, observing correct polarity. Secure the module to the rack.
Usage Notes: Ensure input voltage does not exceed 30 VDC. Observe ESD precautions. Verify jumper configuration (source/sink) matches field wiring. Do not operate beyond 60 °C ambient.
