What Is SCADA? Supervisory Control Without Replacing the PLC
SCADA sits above PLCs and RTUs: it acquires field data, alarms operators, and issues supervisory commands across plants and remote assets—without replacing local deterministic control.

Facilitating high-performance distributed control in industrial networks, the Omron DRT2-OD16 serves as a highly reliable remote transistor output terminal for DeviceNet systems. This output block is engineered with an NPN internal common configuration, permitting seamless interfacing between modern PLC networks and low-voltage field actuators. Supporting 16 solid-state transistor output channels, the unit provides fast response times and integrated diagnostic capabilities, such as communication error logging and power supply voltage monitoring, ensuring minimum downtime in automated environments.

For reliable communication and optimal electrical isolation, mount the module securely inside an IP54-rated (or higher) protective enclosure onto standard 35mm DIN rail. Maintain adequate spacing from high-voltage cables and variable frequency drives (VFDs) to prevent electromagnetic interference. Utilize standard DeviceNet-compliant shielded cabling for network communication, ensuring the network drain wire is grounded at a single point in the system layout.
