ELENE LNL-2220 Intelligent Dual Reader Controller adapter

SKU CH-Y2WD-ZEY9A

An intelligent dual reader controller with 10/100 Ethernet, dual RS-485 downstream ports, four 5 A relay outputs and 50,000-event battery-backed storage

  • 10/100Base-T Ethernet port enables fast network integration
  • 12 or 24 VDC input with ±15 % tolerance ensures flexible power options
  • 50,000 events stored in battery-backed memory provides extensive audit capability
  • 16 supported formats including 8 card and 8 asset types offers versatile credential handling
  • 4 Form-C 5 A relay outputs at 30 VDC deliver reliable door and auxiliary control

Access control controller for two readers

The Lenel LNL-2220 manages two door readers and four relay outputs from a single unit. It suits installers who need a compact panel for small to medium access deployments. The board stores 50,000 events and 32,000 access permissions in battery-backed memory. Eight card formats and eight asset formats are supported alongside biometric templates.

12-24 VDC power with Ethernet uplink

The controller draws up to 500 mA at 12-24 VDC or 400 mA RMS at 12 VAC. A 10/100Base-T port provides the primary network link. An RS-232 upstream port runs at 9600 to 115.2 Kbps. Two RS-485 downstream ports operate at 9600 to 38.4 Kbps for reader and device connections.

Replaces standalone single-door panels

Upgrading from individual door controllers reduces wiring and centralises event storage. The jump is worthwhile when managing multiple doors that share schedules, anti-passback rules or elevator control for up to 128 floors. Buyers who need more than two readers per panel or who require fibre uplink connectivity should look elsewhere.

Questions about this item

How do I wire the 12-24 VDC supply and the Ethernet link, and which step is most often missed?

Connect DC power within the ±15 % tolerance to the 12 or 24 VDC terminals, then plug the 10/100Base-T port into the network. The step most often missed is configuring the DHCP extended command so the controller receives its DNS name before it tries to register upstream.

Which on-board component will need replacement first, and what is its specification?

The 3 V lithium backup cell (type BR2325, BR2330 or CR2330) maintains memory and clock when main power is lost; plan to swap it during scheduled maintenance once its voltage drops below specification.

What is the first capacity limit reached when the system runs continuously at high throughput?

The event log holds 50,000 records in battery-backed non-volatile storage; once full, new events overwrite the oldest unless the host software off-loads them regularly.
