Product Description

Yokogawa DCS AAI143-H00 S1 General Specifications Analog I/O Modules affordable price

Product Description:

Optical ESB bus node units (ANB11S and ANB11D), ER bus node units (ANR10S and ANR10D) (*1), and field control units (for FIO) (AFV30S, AFV30D, AFV40S, AFV40D, AFV10S, AFV10D, AFF50S, and AFF50D). These analog I/O modules function as signal converters; by inputting field analog signals into these modules, it converts them to internal data for field control stations (FCS), or the FCS’s internal data to analog signals for outputs.

Product's Character:

A Zener barrier is not allowed to be connected with this module. Use an isolation barrier when the module is used in intrinsically safe application.  The module input resistance viewed from the terminals depends on the current strength as calculated as below: 250 Ω + current value voltage drop in the input protection circuit F01E.ai . This voltage is generated between the connecting terminals for 2-wire transmitters for this module. When calculating the minimum operating voltage for transmitters, consider to allow margins for voltage drop in external wiring.
