Features

The M-7033D is a 3-channel RTD input module with a 41/2 digit LED display. The M-7000 series is a family of network data acquisition and control modules that support Modbus RTU. They can be remotely controlled using a set of commands called DCON protocol. With the Modbus RTU protocol, it can easily communicate with most popular SCADA/ HMI software and PLCs.
