Description
The M-7000 series is a family of network data acquisition and control modules that support Modbus RTU and DCON protocols. With the Modbus RTU protocol, the modules can easily communicate with most popular SCADA/ HMI software packages and PLC's. It has the same form factor as the I-7000 series.
The M-7080B offers 2 input channels which can act as 32-bit counters or be used for monitoring frequencies up to 100kHz. Two Digital Outputs are also included. Virtual Battery Backup is also provided for Counter mode.
