Informacije o izdelku "M-7018R-G 8-ch Thermocouple Input Module, 240 Vrms Overvoltage Protection"
The M-7018R-G is an RS-485 analog input module with eight differential channels for thermocouple, voltage and current measurement. It suits engineers who need to read temperature sensors and process signals on a networked DIN-rail module, with the option of Modbus RTU or DCON selected in software.
Why choose the M-7018R-G: The R variant adds a high level of input protection, with overvoltage tolerance up to 240 Vrms and 200 VDC common voltage protection. Open wire detection for thermocouple channels is software selectable, which helps identify broken sensor wiring. The gray-cover version is the ordering option covered by this listing.
Channels can be configured individually, and the module provides 3000 VDC isolation between internal circuits, 4 kV ESD protection on each terminal and a built-in dual watchdog for module and communication monitoring. It is rated for operation from -25 ~ +75 °C.
