Remote I/O Terminal with Relay Outputs
DRT2-ROS16
A Smart Slave with Relay Outputs and
One-step Relay Replacement for
Remote Maintenance.
• Capable of handling large-capacity output devices (3 A max.)
• Easy relay replacement.
• I/O expansion possible to transistor I/O devices with terminal blocks (XWT
Series).
Smart Slave Functions
* Applicable only when an Expansion Unit (XWT Series) is used.
