Butler DO41738 Circuit Board Module Assembly

Butler DO41738 Circuit Board Module Assembly is a replacement backplane module for PLC systems, described as a PLC AC I/O circuit board assembly, designed to substitute for a failing or worn-out adapter in compatible Butler chassis. The part number DO41738 identifies this specific module within the Butler I/O ecosystem, and the designation “AC I/O” indicates its role handling alternating current input/output signals for field devices, enabling reliable connection between the main controller and sensors, actuators, and other automation components. Typically installed in compatible backplanes of Butler controllers, the module is used to restore I/O functionality in legacy systems, making it a critical piece for maintenance and uptime in manufacturing environments where downtime is costly and ongoing support depends on genuine replacement parts. As a genuine Butler component, the DO41738 module is engineered to fit standard backplane connectors and conform to the timing, electrical characteristics, and mounting standards of Butler PLC hardware, offering a direct, drop-in replacement option for technicians working with older AC I/O configurations.
