Product Performance
High-precision Acquisition Performance: Possesses high-precision digital signal acquisition capability, can accurately capture various digital signals in industrial sites, with no distortion and no delay in acquisition, ensuring the accuracy of signal transmission, and meeting the strict requirements for signal acquisition precision in safety-critical scenarios.
Redundant Fault-tolerant Performance: Adopts redundant design architecture, can automatically detect and isolate faulty channels, when a single channel fails, it does not affect the normal operation of other channels, the system operates continuously and stably, no single point of failure, ensuring continuous availability of safety-critical applications.
Comprehensive Diagnostic Performance: Built-in complete diagnostic functions including open-circuit detection, short-circuit detection, channel fault self-diagnosis and power fault diagnosis, can monitor the status of input channels and power supply in real time, quickly report faults to the system when faults occur, supports remote diagnosis and maintenance, shortens fault troubleshooting time and improves system maintainability.
Anti-interference Performance: Complies with EN 61000-6-2/6-4 electromagnetic compatibility standards, possesses strong anti-interference ability, can effectively resist various interferences such as power grid harmonics, equipment start-stop impact and space electromagnetic radiation in industrial sites, no signal disorder and no false triggering during long-term operation.
Wide Temperature Adaptation Performance: Operating temperature covers -40℃ to +70℃, can work stably in extremely cold or high-temperature environments, adapts to various harsh industrial sites, no constant temperature control required, trouble-free operation all-weather.
Hot Swap Performance: Supports online hot swapping, can replace the module without stopping the system, does not affect the overall system operation, reduces unplanned downtime and improves factory production efficiency.
System Compatibility Performance: Perfectly adapts to TRICONEX Trident series and Tricon CX series safety control systems, can be seamlessly connected with the same series of digital output modules, analog modules and communication modules, completes system integration without additional debugging.
Contact Compatibility Performance: Compatible with dry contact and wet contact input, adapts to different types of on-site sensors and equipment, no additional adapter components required, reducing on-site deployment cost and difficulty.
