Cold Junction Compensation (CJC) and Thermal Management
The SDN 20-24-100C is designed to maintain thermal stability during high-load operations. When integrated into systems utilizing analog inputs, it supports proper loop power distribution, which is required to prevent thermal drift in signal conditioning circuits. Precise regulation is maintained to ensure that sensitive components, such as those relying on cold junction compensation (CJC) for temperature sensing, receive constant voltage, thereby preventing signal measurement errors caused by voltage fluctuations across the power distribution network.
Frequently Asked Questions (FAQ)
Q: Can the 24 VDC output be connected in parallel with another power supply module?
A: Paralleling outputs should only be performed if the specific module revision explicitly supports load sharing or redundant configuration modes. Refer to the system wiring diagrams to confirm if diode-ORing or parallel operation is permitted for this specific catalog number.
Q: What are the thermal clearance requirements for mounting this power supply?
A: Ensure at least 5 cm of free air space is maintained above and below the module to allow for natural convection cooling. Avoid installing heat-generating components directly adjacent to the power supply to prevent premature derating.
Field Installation Guidelines
- Mount the module on a standard 35 mm DIN rail, ensuring the locking clip is fully engaged to prevent movement.
- Terminate AC input wiring and DC output cabling according to the terminal designations printed on the module housing.
- Utilize wire ferrules for all connections to ensure low contact resistance and prevent conductor fraying.
- Ensure the cabinet earth ground is connected to the designated chassis terminal to provide a reference for noise filtering and transient protection.
- Verify output voltage at the terminal block using a calibrated multimeter prior to connecting critical I/O loads to ensure proper regulation.
