NCS-TT108PC Rail-Mounted 8-Channel Profibus PA Temperature Transmitter

NCS-TT108PC

Product Overview

NCS-TT108PC Smart Temperature Transmitter is an eight-channel, DIN-rail-mounted temperature transmitter designed for multi-point temperature measurement in industrial field applications. It supports measurements from various types of resistance temperature detectors (RTDs), thermocouples (TCs), resistors (Ω), and voltage (mV) sensors, and is compatible with the Profibus PA communication protocol. The product has obtained multiple international certifications, including explosion-proof and PI, and is widely used in process industries such as petroleum, chemical, power generation, and metallurgy.
