Hanwha NOP-IO168S Access Control I/O Expansion Panel
The Hanwha NOP-IO168S is a downstream I/O expansion panel engineered to extend the input and output capabilities of NOP Series IC controllers. Designed for integrators building scalable, encrypted access control systems, this panel delivers 16 supervised inputs and 8 Form-C relay outputs with enterprise-grade security and multi-drop serial communication over a single RS485 line.
Key Features
- 16 high-precision supervised inputs with hardware and software filtering to minimize false alarms
- 8 Form-C relay outputs rated 2A @ 30VDC for auxiliary device and zone control
- Expandable I/O architecture with 1 plug-in module port supporting up to 8 additional relay outputs
- 2 dedicated unsupervised inputs for cabinet tamper and power failure monitoring
- Configurable input modes supporting both supervised and unsupervised operation
- Integrated elevator control support for streamlined access and security workflows
Security and Communication
- OSDP Secure Channel protocol with custom encryption key support
- AES 128/256 and SHA256 encryption for all data transfers
- Secure Boot and firmware encryption at rest
- Upstream RS485 serial communication (9,600 to 115,200 baud configurable)
- Multi-drop support for up to 16 I/O and reader interface boards on a single serial line
- Offline mode operation for continued functionality during network interruptions
Technical Highlights
Advanced filtering technology eliminates nuisance alarms while maintaining supervised integrity across all 16 inputs. The panel's modular design allows installers to scale I/O capacity without replacing hardware. Dedicated tamper and power failure inputs provide critical system health monitoring, while Form-C relay outputs deliver flexible switching for door locks, gates, warning signals, and zone management.
Applications
The NOP-IO168S is ideal for enterprise access control deployments requiring distributed I/O management across large facilities, healthcare campuses, data centers, and multi-site security infrastructures. Its encrypted communication and offline capabilities make it suitable for high-security environments where data integrity and system resilience are paramount.

The NOP-IO168S stands out in the Hanwha ecosystem for its flexible architecture and robust encryption. Multi-drop RS485 topology reduces installation complexity by consolidating multiple expansion panels over a single serial backbone, lowering cabling costs without sacrificing security. The combination of supervised inputs with configurable thresholds and Form-C relays creates a foundation for both access control and auxiliary alerting, while OSDP Secure Channel integration ensures compliance with modern security standards.
Offline mode is particularly valuable for mission-critical facilities where temporary connectivity loss cannot interrupt door control or zone management.
