GSI127 Gets an Upgrade: 244-127-000-021 Replaces the Previous Model with Enhanced Performance
زمان: January 05, 2026
In industrial measurement and monitoring scenarios, equipment stability and adaptability directly influence production efficiency, and a dependable galvanic separation unit is essential for safeguarding machinery operation. As a widely used core component in the industry, the GSI127 series has recently undergone a significant upgrade — the older GSI127 244-127-000-017 will be gradually replaced by the new GSI127 244-127-000-021, which retains all the advantages of its predecessor while achieving comprehensive performance improvements.
The new GSI127 244-127-000-021 is fully form, fit, and functionally compatible with the older GSI127 244-127-000-017. Users can directly replace the old model without modifying their existing equipment layout, eliminating additional debugging costs associated with upgrades. One of the most notable enhancements of this upgrade is that the new product has obtained SIL 2 functional safety certification in accordance with the IEC 61508 standard, enabling it to meet the stringent requirements of safety-related applications and adding an extra layer of protection to industrial production.
In terms of core performance, the new model achieves multiple breakthroughs: its operating temperature range has been extended to -20°C to 70°C (-4°F to 158°F), compared to the older model’s 0°C to 70°C (32°F to 158°F), making it more adaptable to harsh low-temperature environments. It also features lower output noise, along with improved power supply noise rejection (PSRR) and frame-voltage rejection (CMRR), significantly enhancing signal transmission stability. Additionally, the newly added B11 ordering option allows the GSI127 244-127-000-021 to be compatible with more industry-standard sensors, including 4 to 20 mA loop-powered sensors, expanding its applicability.
The older GSI127 244-127-000-017 will remain available for delivery until the end of Q2 2024, nowdays the new orders are all GSI127 244-127-000-021. For users currently using the older model, there is no need to worry about application continuity — the new product is fully equivalent to the old one in form, installation, and functionality, while offering superior performance in dynamic operating range, environmental adaptability, and safety.
Whether for new project selection or old equipment upgrade and replacement, the GSI127 244-127-000-021 can meet diverse needs with its more comprehensive performance and broader compatibility. Building on the reliable foundation of the GSI127 series, this upgraded product incorporates improvements tailored to real industrial requirements, making it a preferred component in measurement and monitoring scenarios and delivering more stable and secure user experiences.
