Process Control/Redundant Supported products
Functional modules for process control (MELSEC iQ-R Series)
While inheriting the features of the MELSEC-Q Series, even faster and high-resolution isolated analog I/O modules are available. By utilizing I/O modules with diagnostic functions and HART® communication protocol supporting analog input modules, a system that enables preventive maintenance of devices and improves its serviceability can be built.

Diagnostic function enables preventive maintenance
I/O modules with diagnostic functions include cable-disconnection and short-circuit detection functions, which are not available on regular I/O modules. By monitoring disconnections and short circuits, system malfunctions can be prevented before they occur.
Provides channel-to-channel isolation and low-cost system construction
In the process control systems, galvanic channel isolation between analog input and output channels is required to prevent current and noise interference. Due to the large number of analog inputs and outputs, it is necessary to reduce the module price per channel. The 16-channel analog I/O modules, which support the same connector shape as the 8-channel, enables system construction at a low cost.
HART® communication enables communication with field devices
Communication with field devices supporting HART® communication is possible. The HART® communication protocol supporting analog input module can read the data held by each device and write parameters to each device. Preventive maintenance of field devices and reduction of maintenance time can be realized.
