1. Brief Introduction
NCS-TT106H-V2.0 is a new generation of smart fieldbus temperature transmitter based on fieldbus technology. It is an essential field device for process control.
The transmitter integrates rich function blocks, supporting both general measurement and complex control strategies. It uses digital technology and can connect to various thermocouple and RTD sensors. With a wide measuring range and simple field-to-control-room interface, it significantly reduces installation, operation and maintenance costs.
NCS-TT106H-V2.0 supports HART protocol and is widely used in petroleum, chemical, power and metallurgical industries.
2. Installation
2.1 Dimension
2.2 Installation Use two screws through the positioning holes to mount the temperature module onto the temperature housing or DIN rail.
2.3 Wiring
- Power and bus signal share one pair of cables (bus cable).
- It is recommended to use IEC 61158-2 compliant fieldbus cable.
- Do not share conduits or cable trays with high-power equipment.
- Keep away from high-power devices.
- Ground the shield wires at both ends of the bus.

4. Maintenance
| Phenomenon | Solution |
|---|---|
| No communication | Check bus cable connection, power polarity, shield grounding (single-point). Replace module for testing if necessary. |
| Reading error | Check sensor short/open/ground; adjust damping; check housing grounding and terminal moisture; keep cables away from strong EMI; verify sensor type and function block parameters. |
