UW5863 Intrinsically Safe Dual-channel Digital Input Module realizes the inspection, latch and protection of dual-channel digital input data.
This Intrinsically Safe Dual-channel Digital Input Module has passed the inspection in accordance with GB3836.1 and GB3836.4 standards and obtained an explosion-proof certificate. It is suitable for installation and use in safe areas, and can be used with intrinsically safe equipment in Zones 0, 1 and 2 of explosive gas hazardous locations.
Functional features
Supports 2-way switch or proximity switch input, switching frequency <10Hz;
The short circuit current is about 8mA; the open circuit voltage is about 8.2V;
When the on-site switch is closed or the loop current is >2.1mA, it is a "1" signal; when the on-site switch is open or the loop current is <1.2mA, it is a "0" signal;
Online automatic diagnosis and operating status display, rapid identification of fault points, automatic identification of disconnections;
Complete isolation between modules and systems and between modules to keep out external interference;
Surge protection and online plug-in support circuit support module online plug-in and online replacement;
Low ripple, low temperature drift, high efficiency, high stability, high withstand voltage isolation power supply design, with multiple protections such as soft start, input short circuit protection, output power limit, and power distribution output current limit.
