The PR-E-16DC-DA-R expansion module adds eight inputs and eight relay outputs to your Rievtech PLC system.
Powered from 12-24 V DC (10.8-28.8 V), it provides extra analogue measurement capability and high-current switching.
🔧 Technical Highlights
- Supply 12-24 V DC with operating limits 10.8-28.8 V; maximum startup current around 0.25 A and typical consumption 1 W.
- Eight inputs: four analogue inputs (0-10 V with 9-bit resolution 0.015 V and ±0.03 V accuracy) and four digital inputs.
- Eight relay outputs: Q1-Q4 rated 3 A and Q5-Q8 rated 10 A at 250 V AC for switching various loads.
- Rapid I/O update time ensures timely response for control loops and sequencing.
- Compact module (~300 g) mounts on DIN rail or wall and operates from -20...55 °C.
✅ Benefits
- Expands your controller's I/O capacity without replacing the base unit.
- Mix of analogue and digital inputs supports sensors and switches in one module.
- High-power relays control both low and high current loads such as motors, lamps and solenoids.
🚀 Applications
- Machinery requiring additional analogue measurement and control channels.
- Process control systems with multiple sensors and actuators.
- Retrofit projects where extending the existing PLC capacity is more economical than replacing it.
❓ FAQ's
- Q: Can I connect this module to any Rievtech PLC?
A: It is compatible with Rievtech PR and EXM series PLCs that support expansion via the side connector.
- Q: Are the relay outputs isolated from each other?
A: Yes. Each relay output is isolated and rated for switching up to its specified current.
