The PR-18DC-DA-R PLC combines analogue measurement with flexible digital control.
Powered from 12-24 V DC (10.8-28.8 V), it offers six analogue inputs, six digital inputs and six relay outputs, making it a versatile automation controller.
🔧 Technical Highlights
- Supply voltage 12-24 V DC with operating limits 10.8-28.8 V and built-in polarity protection.
- Six analogue inputs accepting 0-10 V signals with high-resolution conversion and six digital inputs including high-speed counters up to 60 kHz.
- Six relay outputs rated 10 A for switching resistive or inductive loads.
- 1024 timers, counters and function blocks; built-in RS232 and RS485 communication using Modbus RTU/ASCII protocols.
- Expandable up to 16 modules; operating temperature -20...55 °C; IP20 housing; dimensions 95x90x55 mm and weight around 400 g.
✅ Benefits
- Mixed analogue/digital inputs reduce the need for separate signal conditioning equipment.
- High-speed counters support flow, speed or position measurement for dynamic processes.
- Relay outputs provide robust control of motors, solenoids and heating elements.
- Scalability through expansion modules extends the controller as your system grows.
🚀 Applications
- Industrial automation such as machine control, packaging and assembly lines.
- Energy management systems measuring and controlling voltage-based sensors.
- HVAC and building control where mixed analogue and digital signals are required.
❓ FAQ's
- Q: Are the analogue inputs isolated?
A: The analogue inputs are referenced to the common system ground but include filtering and protection for stable measurements.
- Q: Can I add more outputs later?
A: Yes. Up to 16 expansion modules can be added to increase I/O capacity as needed.
