This Intrinsically Safe Analog Output 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.
Through software configuration, it supports analog output of 0~10mA, 0~20mA, and 4~20mA;
Automatically performs ambient temperature compensation and zero point and gain correction, no adjustment or maintenance required;
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;
Abnormal status configuration function, you can choose to output hold or output user set value;
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.
