š¹ Description
TheĀ AAI143-H00 S1Ā is a 16-channelĀ isolated analog input moduleĀ designed for high-reliability industrial automation systems. It supportsĀ 4 to 20 mAĀ analog signals and includesĀ digital communication (HART protocol)Ā for advanced diagnostics and configuration over the same signal lines.
TheĀ āH00āĀ suffix indicates:
Ā
-
H: HART digital communication enabled
-
0: Basic type (no G3/environmental or extended temperature options)
-
0: No explosion protection
TheĀ āS1āĀ tag typically refers to aĀ hardware series or version identifier.
