I/O Module Part Numbers — Suffix Codes Define the Configuration
The Yokogawa AAT145-S00 is not defined by its base model number alone. The suffix codes — the characters after the base part number — determine input voltage range, output type, channel count, isolation rating, and communication protocol. Two modules that share the same base number but differ by one suffix character can be completely incompatible. This is the most common cause of "the replacement does not work" calls we receive.
Before ordering, verify the full part number from your existing module label. Send us a photo if unsure — our engineers cross-reference and confirm within 4 hours. Every module ships factory-sealed and functionally tested on a live Yokogawa rack. Printed test report. 12-month warranty. Ships within 24 hours.
Compatible Parts — Same System
These modules share the same system family as the AAT145-S00. Commonly ordered together for complete rack builds or spare parts kits.
