S800 Backplane Bus Integration and Deterministic Scaling
This power supply is highly integrated with S800 I/O and industrial network architectures, enabling high I/O density scaling by offering a dependable, ripple-free power backbone. High-frequency filtering maintains optimal backplane bus communication velocity across adjacent terminal cards while minimizing signal interference. Thermal heat sink dissipation profiles are integrated into the chassis design, keeping internal module temperatures stable without requiring active fan cooling.
Frequently Asked Questions
Q: How can the output voltage of the CP-E 24/20.0 be adjusted?
A: The output voltage can be set manually between 22.5 and 28.5 V DC via the rotary potentiometer located on the front face, allowing compensation for line voltage drops over long cable runs.
Q: Does the power supply support parallel operation for redundancy?
A: Yes. The module features an integrated "parallel connection" switch on the front panel to ensure equal current distribution when multiple units are wired in parallel to increase current capacity or establish redundant operations.
Q: How does the module handle short circuits and overloads?
A: The unit utilizes a continuous current limitation design. In the event of an overload or short circuit, the output voltage drops to restrict the overall load profile, returning automatically to nominal operational values once the fault is cleared.
Field Installation Guidelines
- Mount the power supply vertically on a standard 35 mm DIN rail, keeping a minimum clearance of 25 mm horizontally and 80 mm vertically from adjacent heat-producing devices to support natural convection cooling.
- Connect input AC or DC lines to the screw-clamp terminal block located on the bottom left, ensuring the protective earth ground wire is securely terminated first.
- Route all 24 V DC output lines through separate cable trunking away from the high-voltage AC mains wiring to avoid electromagnetic noise transfer.
- Use copper conductors rated for at least 75 deg C to withstand the operating currents and thermal dissipation from the chassis termination zones.
