Performance Parameters: Signal response time less than 1ms; strong anti-interference performance under industrial field environment; meet industrial EMC standards; support 7×24 hours uninterrupted continuous operation.
Material Composition: Glass fiber epoxy multilayer PCB circuit board; photoelectric isolation chips; gold-plated edge connector; metal front panel; circuit board coated with three-proof protective coating.
Structural Features: Rack plug-in modular structure; front panel equipped with LED indicators for power, running and channel fault status; rear gold-plated edge connector connects to MaxPAC rack backplane bus; field signal circuit and system logic circuit are physically separated; panel fitted with mechanical locking buckle.
Working Principle: Field 24VDC switching signals are transmitted to IOP114 and IOP302 modules through supporting terminal base. Photoelectric isolation components separate field circuit and system circuit. The module judges high and low level state and converts into digital logic signal. Data is uploaded to MaxPAC controller via backplane bus. The module detects circuit fault and uploads alarm information.
Installation Requirements: Install in designated slot of MaxPAC I/O rack and match with original supporting terminal base. Use shielded cable for switching signal wiring. Signal cables and high-power power cables are laid in separate trunking. Cabinet protective grounding terminal must be connected reliably. Reserve ventilation space around module.
Precautions for Use: Confirm input signal voltage level before power on. Cut off field loop power before wiring. Do not access high voltage signal to input channel. Cut off rack backplane power before module disassembly. Wear anti-static wristband during operation. Check terminal tightness regularly.
