It features a versatile 12/24 VDC power supply, six robust relay outputs, and RS-485 communication enabling up to 4,000 feet of multidrop connectivity. Designed for professional-grade security systems, it supports up to 16 card formats and offers advanced offline access modes, making it an essential component for scalable, secure, and flexible access control solutions. ## Description LenelS2 offers a Dual Reader Interface (DRI) module for access control solutions. Most access control card readers, keypads, or readers with keypads that use standard Wiegand Data1/Data0 or Clock/Data communication are supported, as are those that support the bidirectional RS-485 Open Supervised Device Protocol (OSDP). Lock, unlock, and facility code offline access modes are supported on all readers connected to the DRI. Each DRI supports up to 16 different card formats as well as issue codes for both magnetic and Wiegand card formats. The DRI provides a vital link between the Intelligent System Controller (ISC) and the card reader attached to the interface. As many as 32 DRI modules can be multidropped using RS485 2-wire or 4-wire communication up to 4,000 feet per port away from the ISC. Each DRI module is individually addressed for increased reporting capabilities with OnGuard access control software applications. The DRI includes eight inputs that support normally open, normally closed, supervised, and non-supervised circuits. In addition, six output relays support fail-safe or fail-secure operation. ## Features - 12 or 24 VDC power supply - Supports Data1/Data0, Clock/Data, Supervised and Unsupervised F2F and OSDP-compatible RS-485 readers and keypads - Supports Open Supervised Device Protocol (OSDP) readers, including biometric template transfer and Secure Channel encryption - Downloadable firmware - Six Form-C 5 A at 28 VDC relay outputs - Up to 16 different formats - Issue code support for magnetic and Wiegand formats ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BMS6JS1J | | Additional Features | High Speed | | Best Sellers Rank | #1,172 in Computer Motherboards | | Brand | ATST | | Color | Red | | Compatible Devices | Access Control Device, Card Reader, Keypad | | Connectivity Technology | RS-485 | | Customer Reviews | 5.0 5.0 out of 5 stars (1) | | Hardware Interface | Serial Interface | | Manufacturer | ATST | | Media Type | MMC | | Model Name | 1320-S3B | | Operating System | Not Obtainable | | UPC | 808237644703 | ## Product Details - **Brand:** ATST - **Color:** Red - **Connectivity Technology:** RS-485 - **Media Type:** MMC - **Special Feature:** High Speed ## Images ![Lenel LNL-1320-S3B - Dual Reader Interface Module Series 3 - Image 1](https://m.media-amazon.com/images/I/815ElQw4W6L.jpg) ## Frequently Bought Together - Lenel LNL-1320-S3B - Dual Reader Interface Module Series 3 - Brady Authentic (M21-750-595-WT) All-Weather Vinyl Label for Indoor/Outdoor ID, Lab and Equipment Labeling, Black on White- For M210, M210-LAB, M211, BMP21-PLUS and BMP21-LAB Printers, .75" W 21' L - Lenel LNL-1320 Access Control Dual Reader Interface Module Series 2 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/491823098-lenel-lnl-1320-s3b-dual-reader-interface-module-series-3](https://www.desertcart.pl/products/491823098-lenel-lnl-1320-s3b-dual-reader-interface-module-series-3) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-29*
