Modules for Easy Replacement

Supported series:

Plentiful Q Series modules facilitate the replacement

DC input module

DC input modules compatible with 6 mA rated input current are available.
When replacing the A/QnA Series modules and utilizing the external devices as they are, the existing Q Series modules may not receive signals sent from external devices, such as proximity sensors, due to incompatibility with low-rated input current, and thus, external resistors need to be installed.
With the QX41-S2 and QX81-S2 modules, which are compatible with 6 mA rated input current, external resistors are no longer required. (The existing external devices can be utilized after replacing modules.)
