The PR-12AC-R micro PLC provides essential control functions in a compact form factor.
It operates directly from a 110-240 V AC supply and combines eight digital inputs with four relay outputs.
🔧 Technical Highlights
- AC supply 110-240 V (85-265 V, 47-63 Hz) with built-in surge and noise filtering.
- Eight digital inputs for sensors, switches and pushbuttons.
- Four relay outputs rated 10 A at 250 V AC or 30 V DC for controlling external loads.
- 512 timers, counters and function blocks support sequencers, delays and counters.
- Non-expandable design with RS232 programming port; operating temperature -20...55 °C and IP20 protection.
✅ Benefits
- Simple all-in-one controller eliminates the need for external power supplies or separate PLC modules.
- Relay outputs provide robust switching for motors, heaters and lighting circuits.
- Onboard timers and counters allow basic control logic without complex programming.
🚀 Applications
- Small machines and equipment that run directly on AC mains.
- Building automation tasks such as lighting or heating control.
- Pumps, fans and simple conveyors requiring basic start/stop logic.
❓ FAQ's
- Q: Can I expand this PLC with additional modules?
A: The PR-12AC-R is a non-expandable model; for expansion, select a PR series PLC with expansion capability.
- Q: Does it support analogue inputs?
A: No. This model is purely digital. For analogue inputs, consider the PR-14DC-DA-R or PR-18DC-DA-R units.
