Traditional control cabinets have numerous drawbacks: troubleshooting a single-line fault takes an average of 60 minutes, installation costs are 38% higher than intelligent systems, and corrosion, vibration, and humidity can all reduce signal integrity. Furthermore, they lack flexibility—modifying I/O requires rewiring. However, UWNTEK's electronic wiring control system, with its software-defined architecture, overcomes these limitations. This system replaces field-to-control-room cabling with intelligent electronic modules and a bus network, achieving unprecedented control capabilities while reducing physical cabling by 95%.
| Feature | Traditional Wiring | UWNTEK EWS |
|---|---|---|
| Signal Transmission | Analog (Susceptible to EMI/noise) | Digital Bus (Fiber/ETH immune to interference) |
| I/O Flexibility | Hardware-defined (Fixed per channel) | Software-Configurable (AI/DI/RTD/HART via software) |
| Fault Tolerance | Single-point failure vulnerability | Dual-redundant Power/Comm/I/O Modules (SIL3) |
| Maintenance Downtime | Hours (Trace > Replace > Test) | <5 mins (Hot-swappable modules) |
| Intrinsic Safety | Requires external barriers/isolators | Barrier Integrated per Channel (Direct Zone 0/1/2 connection) |
| Lifecycle Cost (10-Yr) | $422k (per 1000 I/O) |
$187k (per 1000 I/O) |
1. Elimination of Physical Junction Boxes
The distributed I/O modules of electronic wiring control systems can be directly installed in hazardous areas, reducing signal paths from 500 meters to 10 meters. The elimination of intermediate terminals means an 80% reduction in wiring points and a 60% reduction in copper/conduit material costs.
2. Control Room Space Consolidation
Redundant Ethernet replaces patch panels; a single rack equipped with a UPS can replace 10 traditional patch panels, saving over 1000 square feet of floor space.
A: Absolutely. The electronic wiring control system supports traditional 4-20mA, RTD, and 24VDC signals and can be upgraded via HART 7 passthrough. A phased transition is possible without replacing any equipment.
A: More reliable. Each channel includes dual microprocessor monitoring circuitry and analog verification circuitry. Field data shows that the mean time between failures (MTBF) of software-configurable I/O exceeds 1.2 million hours, while the MTBF of electromechanical terminals is only 200,000 hours.
A: Yes, but under certain conditions. UWNTEK's electronic wiring control system uses parallel voting logic as the output module, and power redundancy requires dual independent power supplies compliant with the ANSI/ISA 84 standard.
A: Yes, if the design is appropriate. UWNTEK has TÜV-certified SIL3 hardware and software for single-channel applications (with diagnostic functions) and has implemented SIL3 certification for dual-channel architecture systems.
