Product Description
The AAB841-S03/M4A00 is a high-performance analog interface module engineered for precision signal management within Yokogawa’s DCS architectures. This dual-purpose unit handles both input and output operations, specifically supporting 1–5 V DC analog inputs and 4–20 mA DC analog outputs. With 8 dedicated channels for inputs and 8 for outputs, it provides a highly efficient solution for multi-loop process control, ensuring seamless communication between field instruments and the system controller.
This specific variant is hardened for challenging environments, featuring the ISA Standard G3 conformal coating for exceptional resistance to corrosive atmospheric gases and rated for operation across an extended thermal range of -20°C to +70°C. The /M4A00 option includes the MAC2-compatible ATM4A-00 adapter, enabling direct integration with established system wiring interfaces.
