1. Decentralized Material Handling Conveyor Control
Utilizing the DRT2-ROS16 in a DeviceNet network to control multiple distributed conveyor motors and pneumatic diverter valves. The 16 relay outputs provide direct switching capability for mixed loads, simplifying field wiring in large warehouse setups.
Problem SolvedMinimizes long wire runs back to a central PLC panel by distributing the I/O near the conveyor motors. The relays provide inherent electrical isolation for noise-heavy motor start/stop circuits.

2. Automated Packaging Machine Mixed-Voltage Control
Deployed in packaging machines where low voltage 24VDC control signals must interact with 250 VAC resistive heaters and AC motor contactors. The isolated relay contacts interface directly with both DC logic and AC loads.
Problem SolvedEliminates the need for intermediary interposing relays by allowing the DeviceNet node to switch up to 2 A at 250 VAC directly per channel, streamlining panel space and reducing BOM cost.

3. Remote Pumping Station with Preventive Maintenance
Integrated into a remote water pumping station panel operating in harsh environments (-10°C to 55°C). The terminal controls various pump starters and solenoid valves while utilizing the Smart Slave function to monitor relay switching operations.
Problem SolvedProvides critical preventive maintenance data by counting the mechanical operations of the replaceable relays, alerting operators before relay failure causes station downtime.
