8-CH, NTC module with modbus RTU protocol (requires PC-DINAL2-17.5) .Reading value in resistance or temperature (° C, ° F, ° K). Each channel can be individually enabled and configured via DIP switches or software. Power supply: 10~40 Vdc or 19~28 Vac Z-8NTC is a data acquisition module up to 8 channels for NTC (Negative Temperature Coefficient) sensors measurement. The The instrument is 3-way isolated up to 1.5 kV from power supply and from the serial communication line. Z-8NTC is characterized by 16- bit A / D conversion on three adjustable scales (100 O - 10 kO, 1 kO -100 kO, 5 kO - 500 kO) and 0,5% accuracy class on resistance value. Reading value is available in resistance (O) or temperature (° C, ° F, ° K) format on full or float 32-bit, direct or swapped. The module enables temperature resistance conversion with SteinhartHart equation and its linearization through configuration software (EASY SETUP). It also allows the possibility to enable and configure single channels and a programmable filter for reading stabilization. Time conversion is equal to 500 ms for all channels and rejection at 50/60 Hz. Wiring of power and serial communication is quick and safe through the bus system housed in the DIN rail. The communication parameters can be configured via DIP switches or via software. Z-8NTC has RS485 serial communication port with ModBUS RTU protocol and Micro USB front port for configuration.
