Concept
RP-C Built-in Power Supply
The RP-C-12A, -12B, and -12C models have a built-in power supply designed to accommodate a nominal operating voltage of 24 VAC at 50/60 Hz or 24 to 30 VDC input power. The RP-C-16A model's power supply is designed for a nominal operating voltage of 230 VAC at 50/60 Hz.
RP-C-12A, -12B, and -12C Models (24 VAC/DC)
The built-in power supply is based on a half-wave rectified, non-isolated design, which is complemented with electronic protection components for transient protection, overload protection, and EMC compliance.
To power the controller, you can use a transformer or a DC power supply:
Class 2 (EN 60742) transformer supplying a nominal 24 VAC at 50/60 Hz
DC power supply supplying a nominal 24 to 30 VDC with the required output power
For more information, see RP-Cs .
RP-C-16A Model (230 VAC)
The built-in power supply is based on a full-wave rectified, isolated design, which is complemented with electronic protection components for transient protection, overload protection, and EMC compliance.
With the 230 VAC input (L and N) galvanically isolated from the electronics, the risk of damage due to earth ground currents is reduced and allows the input power to be wired without concern for polarity matching.
