The RP-C 24 V controller 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 230 V controller models' power supply is designed for a nominal operating voltage of 230 VAC at 50/60 Hz.
For more information, see RP-C Models .
The design of the built-in power supply differs between the RP-C 24 V controller models, which in that respect can be divided into the following two categories:
Models with an “-F” in the product name:
RP-C-12A-F-24V, RP-C-12B-F-24V, RP-C-12C-F-24V, and RP-C-16B-F-24V
Models with an “-M” in the product name:
RP-C-12A-M-24V, RP-C-12B-M-24V, and RP-C-16A-M-24V
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

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.

The 24 VAC/VDC power input is galvanically isolated from the electronics. This minimizes the risk of damage due to earth currents and permits the input power to be wired without concern for polarity matching.
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) electronically 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.
