The Lenel LNL‑1100 Input/Output Module (Series 2) is a high-density, configurable access-control interface that extends OnGuard system functionality. Measuring 6″ (W) × 8″ (L) × 1″ (H), it draws 12 – 24 VDC at up to 350 mA and processes 16 supervised or non‑supervised inputs via configurable EOL supervision. Two Form‑C relay outputs (5 A @ 28 VDC) support fail-safe or fail-secure operation, ideal for door strikes and other devices. Communications occur over RS‑485 multi‑drop (up to 4,000 ft), with DIP-switch selectable addressing, onboard termination, and status LEDs for heartbeat and communications. Inputs are scanned at 60 Hz with 64 ms debounce, and two dedicated inputs monitor tamper and power fault. Rugged design supports −55 °C to +85 °C storage and 0–95 % RH. UL 294, UL-1076, FCC, CE, RoHS compliant, it's downloadable firmware compatible and supports elevator control up to 128 floors. Typical weight is ~9 oz. Show more
