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-7033 is a 3-channel RTD Input module that is used for measuring temperatures via an RTD sensor and supports Pt100, Ni120, and Pt1000 type sensors. This module allows 2/3 or 4-wire RTD connections and features open wire detection. The M-7033 also includes 3000 VDC intra-module isolation, and supports lead resistance elimination for 3/4-wire connections.
