SDC IC-UR48-SPEC vs SDC 101-KDENA: Specification Comparison
Both the SDC IC-UR48-SPEC and the SDC 101-KDENA are wired, 4-door access controllers from the same manufacturer, sharing identical door capacity, credential storage, and dual-protocol communication. A buyer evaluating either unit is looking at enterprise-class panel-level access control for small-to-mid-scale multi-door facilities. The key differentiators lie in physical form factor, power input method, override capability, and peripheral integration details — not in door count or credential ceiling, which are identical across both models.

How do door capacity, credential storage, and protocol support compare between the IC-UR48-SPEC and 101-KDENA?
Both controllers manage exactly 4 independent door zones and store 250,000 credential profiles on-device, so neither unit has an advantage in raw capacity for deployments within those ceilings.
Protocol support is identical: both implement OSDP for encrypted reader communications and TCP/IP for remote network management. The IC-UR48-SPEC spec sheet confirms HID format cards and readers; the 101-KDENA is listed as HID-compatible and additionally specifies a keypad as a reader type, suggesting it may support PIN-based credential entry alongside card-based access. Neither spec documents additional credential types beyond HID-format.
Buyers requiring more than 250,000 users or more than 4 doors will find both units equally limiting and should look at higher-capacity panel lines regardless of which model is under consideration.
How do power input, mounting options, dimensions, and physical override capability differ between the two controllers?
Power supply is a concrete differentiator. The 101-KDENA specifies 24VDC input and also lists PoE (802.3af) as a power option, giving installers flexibility to draw power from a PoE-capable switch without running a separate DC supply run. The IC-UR48-SPEC specs do not document a voltage input or PoE capability, so that information is not available for direct comparison.
Physical form is documented only for the 101-KDENA: 4½" × 6-7/16" × 2" and 2 lbs, with wall and rack mount options. The IC-UR48-SPEC datasheet is referenced but no dimensions, weight, or mounting configuration are listed in the provided specifications.
The 101-KDENA includes an integrated key switch for emergency manual override — a meaningful operational feature in facilities requiring fail-safe or maintenance bypass. The IC-UR48-SPEC specs do not reference any override mechanism.
The 101-KDENA package contents note indicates accessories (including the strike, noted as magnetic lock type) may be ordered separately, which is relevant for total bill-of-materials planning.
What integration, reader compatibility, and warranty differences should installers weigh when selecting between these two models?
Both controllers carry a lifetime warranty, equalizing long-term support risk on that dimension.
The IC-UR48-SPEC is positioned for mid-scale campus environments per its compatibility notes and supports HID format cards and readers specifically. The 101-KDENA is described as HID-compatible and adds keypad reader type in its specs, which broadens PIN-credential scenarios without requiring a separate reader module.
The 101-KDENA's rack mount option (in addition to wall mount) is relevant for installers deploying in IT closets or structured cabling environments where panel space is managed in standard 19" racks. The IC-UR48-SPEC does not list mount type in the provided specs.
Neither unit documents software platform compatibility, API integrations, or access control software requirements in the provided specifications, so buyers must consult SDC directly or reference the respective datasheets at the paths noted (/content/product-datasheets/IC-UR48-SPEC.pdf and /content/product-datasheets/101-KDENA.pdf) for VMS or PSIM integration guidance.
Which should you choose: the IC-UR48-SPEC or the 101-KDENA?
Our take: The 101-KDENA is the stronger choice when installation flexibility, physical override capability, and documented power options are priorities. It uniquely specifies 24VDC input plus PoE (802.3af), eliminating a separate power supply run in PoE-equipped infrastructure — a spec absent from the IC-UR48-SPEC. Its integrated key switch provides emergency manual override that the IC-UR48-SPEC does not document. The 101-KDENA also adds keypad reader type support alongside HID compatibility, and offers both wall and rack mount in a documented 2 lb, 4½" × 6-7/16" × 2" enclosure. Where both units are equal — 4 doors, 250,000 credentials, OSDP/TCP/IP, HID credential type, and lifetime warranty — the IC-UR48-SPEC may suit buyers whose procurement or platform requires that specific model designation. Installers should verify software platform compatibility for both units directly with SDC before specifying either.

Frequently Asked Questions
Which should you choose: the IC-UR48-SPEC or the 101-KDENA?
The 101-KDENA is the stronger choice when installation flexibility, physical override capability, and documented power options are priorities. It uniquely specifies 24VDC input plus PoE (802.3af), eliminating a separate power supply run in PoE-equipped infrastructure — a spec absent from the IC-UR48-SPEC. Its integrated key switch provides emergency manual override that the IC-UR48-SPEC does not document. The 101-KDENA also adds keypad reader type support alongside HID compatibility, and offers both wall and rack mount in a documented 2 lb, 4½" × 6-7/16" × 2" enclosure. Where both units are equal — 4 doors, 250,000 credentials, OSDP/TCP/IP, HID credential type, and lifetime warranty — the IC-UR48-SPEC may suit buyers whose procurement or platform requires that specific model designation. Installers should verify software platform compatibility for both units directly with SDC before specifying either.
Does either the IC-UR48-SPEC or 101-KDENA support more doors or users if my facility grows?
No. Both controllers are hard-specified at 4 independent door zones and 250,000 credential profiles. Neither unit offers an expansion path within these specs, so facilities anticipating growth beyond 4 doors or 250,000 users should evaluate higher-capacity SDC panel lines rather than either of these models.
Can I power the 101-KDENA from a PoE switch instead of a dedicated DC supply?
Yes, based on the provided specifications. The 101-KDENA lists both 24VDC and PoE (802.3af) as power input options, which allows it to draw power directly from a compatible PoE switch port. The IC-UR48-SPEC does not document a power input method or PoE support in its available specs, so that option cannot be confirmed for that model.
Is the IC-UR48-SPEC or 101-KDENA better suited for IT-closet rack installations?
The 101-KDENA is the documented choice for rack installations. Its specs explicitly list both wall mount and rack mount options in a compact 4½" × 6-7/16" × 2", 2 lb enclosure. The IC-UR48-SPEC does not list mounting configuration or physical dimensions in the provided specifications, so suitability for rack deployment cannot be confirmed from the available data alone.
