Key Features

1. Modular & Detachable Design
   • Separates from the D20C processor module for easy installation, maintenance, and replacement
   • Supports hot‑swap of termination boards without system shutdown
   • Dedicated slots for digital input, output, and analog signal termination
2. Versatile Termination Options
   • Compression screw terminals for direct field wiring (max #12 AWG)GE Vernova
   • DB25 connector for interposer relay integration and simplified multi‑core cable connectionGE Vernova
   • Barrier termination option for high‑density, organized wiring in control panelsGE Vernova
3. Robust Signal Integrity & Protection
   • Built‑in surge protection (MOVs) and noise filters reduce electromagnetic interference
   • Optically isolated digital inputs eliminate ground loop noise and enhance safety
   • Channel‑to‑system isolation (1500 VDC) protects the control module from field‑side faults
4. High‑Density I/O Termination
   • Supports 16 digital inputs, 8 relay outputs, and 8 analog channels in a compact footprint
   • Clearly labeled channel numbers and LED status indicators for quick troubleshooting
   • Jumper switches for custom signal mapping and address assignment
5. Industrial‑Grade Reliability
   • Conformal coated PCB for protection against dust, moisture, and chemicals
   • Vibration‑resistant screw terminals maintain connection integrity in high‑vibration environments
   • Flame‑retardant housing meets UL 94 V‑0 for fire safety
