ANALOG INPUT MODULE REPLACEMENT
Production discontinuation
Product Model
Analog input module A68ADN
*1 The Q68AD-G cannot be mounted on the Q series large type base unit (Q3BL, Q6BL, Q55BL).
Point
The existing wiring for the A/QnA series modules can be connected directly to the Q series modules
using the upgrade tool (conversion adaptor) manufactured by Mitsubishi Electric Engineering Co., Ltd.
(1) One slot type (can be mounted on the Q series large type base unit)
Product
Analog input module
(2) Two slot type
(cannot be mounted on the Q series large type base unit)
Product
Analog input module
*1 Replacement for the existing A series modules (large size) in the mixed use of voltage and current.
For the single use of voltage or current, replacing with a conversion adapter of one slot type is possible.
For MELSEC-A/QnA (large type) Series to Q Series transition related products manufactured by Mitsubishi Electric
Engineering Co., Ltd. or Mitsubishi Electric System & Service Co., Ltd., contact your local sales office or
