M-7080B
2-channel Counter/Frequency Input with battery backup. Communicates over Modbus RTU and DCON protocol. Comes with free EZ Data Logger software for data logging and remote monitoring. Supports operating temperatures between -25°C ~ 75°C (-13°F ~ +167°F). Has a din rail mount.
Features
The M -7080B is intelligently designed to provide signal conditioning, system monitoring, and safe value settings. It is a Counter/Frequency Input Module with Battery Back Up that supports modbus RTU. In case of power failure, it will keep the readings due to battery backup. It is a cost-effective solution for a wide range of valuable industrial control signals and systems.
The DCON utility can help users to configure and test the M-7080 High Speed Counter / Frequency Input module. Plenty of library functions and demo programs are provided to let users develop programs easily under Windows, Linux and DOS operating systems. The communication interface is modbus protocol via RS-485 and also Modbus RTU to easily communicate with most popular SCADA/ HMI software and PLCs. Users may mount the modules on a DIN rail, panel or wall. Modules have a screw-terminal block to connect to the signals.
