Yokogawa digital I/O modules are used to connect field devices to programmable logic controllers (PLCs). They are available in a variety of configurations, including input modules, output modules, and combination modules.

• Input modules are used to receive signals from field devices. They can be used to connect a variety of devices, including switches, sensors, and actuators.
• Output modules are used to send signals to field devices. They can be used to control devices such as motors, valves, and lights.
• Combination modules combine input and output channels in a single module. They can be used to simplify the installation and configuration of I/O systems.

Yokogawa digital I/O modules are available in a variety of voltage and current ratings. They are also available in a variety of environmental ratings, including explosion-proof, dust-tight, and water-resistant.
