2. Core Technical Specifications & Functional Features

2.1 Field Wiring Termination Functions

• Equipped with screw-type wiring terminals compatible with multi-core shielded instrument cables widely used on industrial sites; independent terminals are reserved for signal positive/negative poles, shield grounding and loop power supply wiring

• Built-in fixed internal signal jumpers with no need for manual jumper modification on site, perfectly aligning with the channel definition of the upper SOE digital input module

• Supports bus-type cascaded distribution of 24VDC field loop power among multiple adjacent terminal bases for convenient centralized power wiring

2.2 Exclusive Optimization for G13 SOE Application

• Optimized dedicated hardware filtering circuit layout for high-speed event capture, effectively eliminating contact bounce and external electromagnetic interference without distorting fast transient switch signals

• Precision signal routing design minimizes internal transmission delay deviation between different channels, ensuring accurate millisecond-level time tagging of SOE events

• Reinforced anti-loosening terminal screw structure prevents cable terminal loosening caused by long-term cabinet fan vibration and thermal expansion & contraction

• Upgraded module locking mechanism ensures stable gold finger contact after repeated plugging and unplugging, avoiding signal loss or timestamp inaccuracy induced by poor contact

2.3 Electrical Safety & Protection Design

• Isolation barriers arranged between adjacent channel terminals to prevent accidental short circuits during wiring construction

• Reserved installation space for external miniature fuses per individual channel to realize independent overload protection for each signal loop

• Clear silkscreen channel numbering consistent with the upper SOE module, greatly facilitating on-site wiring verification and later loop troubleshooting

• Integrated surge diversion paths work in coordination with the upper electronic module to suppress induced lightning and instantaneous voltage surges transmitted from the field side

2.4 Environmental & Certification Parameters

• Operating Temperature Range: 0℃ ~ +60℃

• Storage Temperature Range: -40℃ ~ +85℃

• Relative Humidity: 5%–95% RH, non-condensing

• Complies with IEC 61000 series industrial EMC electromagnetic compatibility standards

• Certified with CE and UL international industrial safety certifications, fully satisfying wiring specifications for power plants and petrochemical sites

2.4 Standard Operation Guidelines

• Only one upper electronic module can be plugged or unplugged at a time with the system energized; simultaneous replacement of multiple modules is prohibited

• Intrinsically safe explosion-proof loops and field circuits carrying AC power must be fully de-energized prior to disassembly work

• Live removal of the terminal base itself is forbidden; only the docked upper electronic module permits single-card online replacement
