Performance Parameters: Signal response time less than 1ms; stable signal identification under strong electromagnetic interference; meet industrial EMC electromagnetic compatibility 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 active feedback signal is transmitted to IOP114 module through supporting terminal base. Photoelectric isolation components isolate field circuit and DCS system circuit. The module identifies high or low level and converts it into digital signal. Digital data is uploaded to DPU controller via backplane bus. The module detects channel abnormality and uploads alarm message.
Installation Requirements: Install in designated slot of MaxPAC I/O rack and match with original terminal base. Use shielded cable for signal wiring. Signal cables and power cables are laid in separate trunking. Cabinet protective grounding terminal must be connected reliably. Reserve ventilation space around module.
Precautions for Use: Confirm signal voltage level before power on. Cut off field loop power before wiring work. 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.
