Channel-to-Channel Isolation & DCS Field Signal Processing
The terminal board provides structured signal routing pathways that interface field instruments directly with control node I/O modules while maintaining channel-to-channel isolation parameters established by the connected system cards. Internal circuit traces handle 4-20 mA HART loop protocol signal pass-through without introducing impedance attenuation or phase shift. This isolated termination architecture prevents ground potential shifts between field device junction boxes and backplane processing buses, maintaining clean signal transmission across DCS and SIS loops.
Frequently Asked Questions
Q: Can field wiring connections be modified on the TERT terminal board while the system node is active? A: Field wiring can be landed or disconnected individually provided the associated field loop power is de-energized, as the passive board structure does not interrupt backplane bus operations.
Q: How does the pass-through design support HART digital communication signals? A: Internal circuit pathing maintains constant loop impedance and minimal capacitive loading, allowing high-frequency HART digital frequency-shift keying (FSK) signals to pass transparently to analog input/output cards.
Field Installation Guidelines
Mount the terminal board securely on the cabinet DIN rail or rack assembly before terminating field wiring leads. Align the multi-pin system interface cable connector with the corresponding socket on the board, then tighten the retaining screws to ensure continuous ground continuity and signal contact.
For system wiring and cabinet commissioning:
- Strip field wire insulation to 7 mm and land leads into specified screw or spring-clamp terminals.
- Maintain strict separation between analog 4-20 mA instrumentation cables and high-voltage AC power conductors within cabinet wire ducts.
- Terminate signal cable shield drain wires directly at the cabinet main copper grounding busbar to prevent ground loop currents from entering the board.
- Verify torque settings on all screw terminals to eliminate loose contacts and preserve long-term signal integrity.
