MC-TLPA02: Module Model

MC = Module Card (Enhanced Board Card Series)

TLPA = Total Logic Power Adapter (Total Logic Power Adapter)

02 = Hardware Version (Rev.B, Industrial-grade High Reliability Version) Technical Specifications

Input voltage: 24 VDC (±10%), backplane power supply

Output voltage: 5 VDC, ±15 VDC (isolated voltage regulation, accuracy ±0.5%)

Output power: 40 W (maximum) (125 is 25 W, increased by 60%)

Isolation strength: 1500 V RMS (input - output; channel-to-channel isolation enhanced)

Protection mechanism: Overvoltage, overcurrent, short circuit, reverse connection, surge suppression (enhanced protection)

Interface and status

System side: High-density UCN flat cable, compatible with C200/C300/TPS controller I/O backplane

Load side: Removable gold-plated screw terminals (anti-oxidation, supports up to 8 FTA parallel power supply)

Indicators: PWR OK (green), FAULT (red) dual-color LED, fault code visualization

Configuration: Hardware plug-and-play, no software configuration required

Hot swapping: Supported (online replacement does not affect system operation) Core function

High-power and high-density power supply: 40 W output, capable of driving 8 FTA (only 4 for 125), compatible with 32 LLMUX and other high-power I/O board cards

Enhanced isolation and anti-interference: 1500 V RMS isolation, suppressing ground loops and industrial noise, ensuring stable precision signals

Wide temperature and high stability operation: -25°C to +75°C, suitable for harsh industrial conditions such as chemical, metallurgy, and power generation

Comprehensive fault protection: surge suppression + multiple protections, automatically locking and alarming faults, protecting expensive FTA at the back end

Simplifies large system architecture: single module replaces multiple standard power board modules, saving cabinet space and costs Applicable scenarios

Industry: Oil and gas, petrochemicals, large-scale power generation (boilers / steam turbines), metallurgy, chemical industry, pharmaceuticals

Applications: 32-channel LLMUX low-level system, high-density SDI/SI digital I/O, large-scale DCS multi-point precise measurement circuits

Compatibility: Experion PKS (C200/C300), TDC 3000, TPS (full series of FTA universal for UCN network)
