Yokogawa TERT Style A Terminal Block
Configured for precise signal termination in Yokogawa DCS architectures, the Yokogawa TERT, also cataloged as the TERT Terminal Block for RTD, provides direct physical/electrical execution. The unit establishes high-density field connections across 16 wiring points utilizing M4 screw terminals to route low-level Resistance Temperature Detector signals to system input cards. It maintains an insulation resistance of at least 100 M-ohm measured at 500 VDC and provides a dielectric strength rated for 500 VAC withstanding voltage.

Cold Junction Compensation & 4-20 mA HART Loop Integration
The Yokogawa TERT terminal assembly incorporates high-grade thermal isolation paths to ensure accurate cold junction compensation (CJC) reference calculations during low-voltage temperature measurement cycles. Channel-to-channel isolation parameters prevent common-mode noise transfer from degrading resistance readings across long sensor runs. Integrated physical trace geometry allows direct coupling with 4-20 mA HART loop protocol transmitters and FOUNDATION Fieldbus / Profibus PA connectivity networks without introducing signal attenuation or line impedance errors across the 16 wiring points.
Frequently Asked Questions
Q: What insulation test parameters are specified for the TERT terminal block?
A: The TERT terminal block undergoes isolation validation requiring a minimum insulation resistance of 100 M-ohm when tested at 500 VDC between signal terminals and chassis frame.
Q: Can the M4 screw terminals on the TERT block accept standard spade or ring lugs?
A: Yes. The M4 thread size and terminal spacing accommodate standard industrial ring or spade lugs to maintain secure low-resistance connections for RTD wire terminations.
Field Installation Guidelines
- Power & Signal Isolation: Disconnect primary field power and bypass active temperature monitoring loops prior to mounting or attaching field wiring to the TERT terminal block.
- Mounting & Mechanical Fixation: Secure the TERT assembly into the designated Yokogawa I/O chassis slot or baseplate rail using standard mounting screws. Ensure the module latches firmly into place to withstand mechanical vibration.
- Field Wiring Termination: Strip RTD sensor lead insulation to the required length and insert conductors into M4 screw terminals. Torque all terminal screws evenly to prevent loose contacts and thermal drift.
- Shielding & Earth Grounding: Route RTD signal cables in separate grounded metallic conduits away from high-voltage AC lines. Terminate cable shields strictly at the designated system ground bus to prevent ground loops.
