Product Features
ABB NTCL01 supports standard signals such as 4-20mA and ±10V, with an accuracy of ±0.1% FS.
ABB NTCL01 supports dry contacts and TTL level input/output, with a response time of ≤1ms.
ABB NTCL01 can overlay digital communication on the 4-20mA signal to transmit device diagnostic information and supports remote parameter configuration.
ABB NTCL01 features electrical isolation between the field side and DCS side, with an isolation voltage of ≥2500Vrms, preventing ground potential interference.
ABB NTCL01 complies with the EN 61000-6-2 industrial environment standard, with RF interference resistance up to 10V/m.
ABB NTCL01 supports full-duplex communication at up to 1 Mbps. It supports dual-axis cables (up to 1 km) or coaxial cables (up to 5 km), and is compatible with fiber optic expansion modules (requires an external converter).
ABB NTCL01 seamlessly integrates with ABB DCS systems, supports Modbus RTU (RS-485) and Profibus DP, and is compatible with third-party PLC or SCADA systems.
ABB NTCL01 monitors the power supply status of field devices, communication link quality, and signal overload alarms in real time. It features LED status indicators (power, communication, fault) for quick problem identification.
ABB NTCL01 enables remote reading of device parameters via the HART protocol or DCS configuration software. It supports firmware online upgrades without downtime.
Product Using Principle
ABB NTCL01 converts the 4-20mA signal into a 16-bit digital value via an analog-to-digital converter (ADC) and encapsulates it into an InfiNet protocol frame.
It overlays a 1200Hz/2200Hz FSK digital signal on the analog signal to enable bidirectional data exchange.
It uses an internal processor to map Modbus RTU data to InfiNet format and vice versa.
It communicates with the master station (such as the INNIS 01 controller) as a slave station, supporting daisy chain or star topology.
Its dual network ports can connect to two independent links, automatically switching in case of failure. It supports Profibus DP gateway functionality for multi-protocol mixed networking.
Product Application
ABB NTCL01 can be used for data acquisition and remote control of wellhead pressure sensors and flow meters, and supports installation in explosion-proof areas.
It can be used for substation equipment condition monitoring and is compatible with the IEC 61850 standard.
It enables real-time monitoring of analog signals such as reactor liquid level and pH value, and combines with the HART protocol to achieve predictive maintenance.
It enables centralized management of pump station motor current and valve opening, and supports Modbus RTU communication with third-party PLCs.
