Hanwha - NOP-RI4S - Downstream Reader Interface for NOP Series
Product Overview
The Nortech Control NOP-RI4S is a downstream reader-interface panel for NOP series controllers, supporting 4 Wiegand/OSDP reader ports. This interface panel features 12 high-precision supervised alarm inputs, 2 unsupervised dedicated inputs, and 8 Form-C relay outputs. Encrypted data transfer via serial port communication with NOP series controllers provides offline event buffering and advanced access control capabilities.
Key Configuration
• Reader ports: 4 ports supporting Wiegand readers or up to 2 OSDP readers per port (up to 8 OSDP readers total)
• Supervised inputs: 12 configurable high-precision inputs with supervised or unsupervised modes and hardware/software filtering
• Outputs: 8 Form-C relay outputs, rated 2A @ 30VDC max
• Serial port: 1 upstream RS-485 port with multi-drop support for up to 16 I/O or reader interface boards; 9,600–115,200 baud
• Power input: 12–24VDC; typical 310mA, maximum full-load current 3.32A
Key Features
Features secure boot, encrypted firmware and data storage, OSDP secure channel support with custom keys, and AES 128/256 and SHA256 encryption. Offline mode maintains access control operation during controller communication loss, while dedicated inputs monitor cabinet tamper and power failure events. Additional capabilities include occupancy management, elevator control for up to 128 floors, host-controlled access requests, configurable keypad support, status LEDs, and protected auxiliary/reader power outputs. Compliant with CE, UL, FCC Part 15 Class A, and RoHS standards.
Technical Context
Designed as a downstream expansion module for NOP series access control controllers, supporting RS-485 multi-drop communication with up to 16 reader or I/O interface boards. It provides secure communications through encrypted data storage and OSDP secure channel support with custom keys. Supervised high-precision inputs use hardware and software filtering to reduce false alarms, while offline event buffering maintains access control functionality and event logging during controller communication interruptions.
Installation Notes
Measuring 8" × 6" × 0.75" (203.2 × 152.4 × 19.05 mm) and weighing 0.28 lbs (126 g). It operates in extreme temperatures from -40°C to +80°C and supports 12–24VDC power input. Typical current draw is 310mA, with a maximum full-load current of 3.32A. The unit includes fuse-protected power distribution, with auxiliary and reader port outputs provided via protected VIN passthrough for readers and locks.
