Integrator note — what the module is, what it powers
The ABB 1SVR427041R1000 sits in the CP-D range as a 12 V fixed-output, single-channel logic supply built for DIN-rail mounting inside PLC and HMI cabinets. It is rated 10 W with a 830 mA output at 12 V, which sets the load ceiling an integrator has to respect when fanning out to relays, signal conditioners and small HMI backlights. The wide input range covers 90 to 264 VAC and 120 to 370 VDC at a nominal 100 to 240 VAC / 120 to 370 VDC window, which lets the same unit ride either a standard control transformer tap or a battery-backed DC bus without re-specifying the part for the cabinet.
Panel-side fit — footprint, terminations, ambient
On the DIN rail the module takes an 18 mm slot, 57.5 mm deep and 91 mm tall, with screw terminations. That slim 18 mm width keeps it on speaking terms with adjacent CP-D siblings and standard terminal block pitch when the row is laid out for fill factor. Insulation voltage is 300 V, the enclosure protection is IP20, and the operating envelope runs from -40 °C to 70 °C, so placement near cabinet doors, top-hat ventilation slots or co-located drives needs the standard derating watch above 40 °C rather than a special-cabinet compromise.
Sourcing posture — quoting, lifecycle, second source
The lifecycle record on file lists brand as ABB only, with no production-status entry beyond that.
