Frequently Asked Questions
Can I use the DRDN20-24 in a 24V PLC cabinet that needs redundant power paths?
Yes, this model is designed for 24V systems and is rated for 20A with 480W capacity. Its redundancy module design supports 1+1 and N+1 redundancy, which makes it suitable for PLC cabinets built around redundant 24V power architecture.
Is the DRDN20-24 a good fit for industrial automation panels with 24V control loads?
It is suitable for industrial automation panels that distribute 24V control power and need redundancy support. The unit is rated for 20A and 480W, and its 125.2 x 102.0 x 32.0 mm body helps preserve panel space on DIN rail.
Can this model be used in a building automation enclosure for 24V controllers and field panels?
Yes, it fits building automation enclosures where the control side is standardized on 24V and the redundant path must stay within 20A and 480W. Relay contacts for monitoring power status also help when cabinet alarms or supervisory signals are part of the design.
Can the DRDN20-24 be used for redundant 24V power in a compact DIN rail control cabinet?
Yes, the unit is intended for DIN rail installations and has a 32.0 mm profile within its 125.2 x 102.0 x 32.0 mm dimensions. That slim form factor is useful in compact control cabinets that still need 24V redundancy up to 20A.
How does the DRDN20-24 compare with the other DRDN20 models?
The DRDN20-24 is the 24V version of the DRDN20 series and is rated for 20A and 480W with a 19-29VAC input range. The DRDN20-12 is 12V, 20A, and 240W with 9-14VAC input, while the DRDN20-48 is 48V, 20A, and 960W with 36-60VAC input. All three use the same 125.2 x 102.0 x 32.0 mm housing, weigh 0.35 kg, operate from -40°C to +80°C, and carry CB, CE, EAC, and UL certifications.
Should the DRDN20-24 be used inside a cabinet or in an exposed environment?
The available specs support use in industrial control environments and list operation from -40°C to +80°C, but no IP rating is provided. In practice, that points to use inside a control cabinet or enclosure rather than in an exposed location.
