RXIDK 2H 1MRK000838-HA
RXIDK 2H 1MRK000838-HA Industrial-grade Redundant Digital Input Module
Product Description
The RXIDK 2H 1MRK000838-HA is a high-reliability redundant digital input module designed for critical industrial control systems, specializing in the acquisition and processing of discrete signals from safety-critical field devices such as emergency stop buttons, safety interlocks, and fault detectors. It features dual-channel redundancy to ensure uninterrupted signal monitoring even in the event of a single channel failure, making it ideal for applications where system downtime could lead to safety risks or significant production losses. This module is widely used in power generation, oil and gas processing, and nuclear facilities, providing a robust interface for safety instrumented systems (SIS) and critical control loops.
In a 1000MW coal-fired power plant’s boiler protection system, the RXIDK 2H 1MRK000838-HA module monitors 16 safety interlock signals (flame detectors, pressure switches) with dual-channel redundancy. It achieves a fault detection coverage of 99.9% and a safe failure fraction (SFF) of ≥90%, enabling the system to meet SIL 2 safety requirements and reducing the probability of spurious trips by 35%. In an offshore oil platform’s emergency shutdown (ESD) system, it collects 12 emergency stop signals, with a signal transmission laten
