Yokogawa TERT*A Terminal Block
Configured for multi-point temperature sensor signal termination in Yokogawa DCS platforms, the Yokogawa TERT*A (TERT Terminal Block for RTD) provides direct physical/electrical execution. It interfaces directly with field-mounted Resistance Temperature Detectors (RTD) across 16 termination points, routing precise low-resistance voltage drops to system analog input modules.

Cold Junction Compensation and Channel-to-Channel Isolation
The TERT*A terminal block maintains tight electrical isolation and low-resistance contact paths required for temperature measurement stability. High insulation resistance (at least 100 Mohm at 500 V DC) and a 500 V AC withstanding voltage prevent common-mode noise coupling and ground loops across adjacent RTD channels. Thermal equalization across the M4 screw terminals minimizes parasitic thermocouple effects, ensuring accurate signal conversion when paired with system RTD input cards equipped with cold junction compensation (CJC) processing.
Frequently Asked Questions
Q: What screw size and torque considerations apply to the TERT*A terminal connections?
A: The terminal block uses M4 screw terminals. Field wiring ring or spade lugs must be secured to standard M4 torque specifications to ensure low contact resistance and prevent signal degradation on RTD leads.
Q: How does the insulation rating of the TERT*A impact noise immunity across channels?
A: The unit features an insulation resistance of at least 100 Mohm at 500 V DC and 500 V AC dielectric strength, preventing cross-channel interference and leakage currents across all 16 contact points.
Field Installation Guidelines
- Terminal Termination: Strip RTD lead wires and crimp with compatible M4 spade or ring terminals. Secure tightly onto the M4 screw blocks without over-torquing.
- Cable Shielding: Connect overall temperature cable shields to the main cabinet ground bar. Maintain separation between sensitive RTD signal wiring and high-voltage power lines.
- Environmental Inspection: Ensure operating ambient conditions remain within 0 to 50 deg C and 5 to 90 %RH non-condensing to prevent insulation degradation across the terminal block body.
