Yokogawa AIP171 – Industrial Transceiver Control Unit

The Yokogawa AIP171 serves as a critical interface between field devices and control systems in process automation environments. This compact transceiver excels at converting analog signals to digital data for transmission across Modbus RTU networks, particularly valuable in scenarios requiring precise monitoring of temperature, pressure, and flow parameters.

In field applications, we’ve seen this unit perform exceptionally well in harsh environments – one customer in a Middle Eastern oil refinery reported stable operation despite ambient temperatures exceeding 55°C. Its 12-24V DC power range makes it compatible with both legacy and modern control cabinets, and we’ve successfully integrated it with ABB AC1027 drives, GE VMIVME-7807 modules, and Honeywell DCS systems. The combination of Modbus RTU protocol and compact form factor makes it ideal for retrofitting older installations while maintaining communication integrity.

Our inventory includes both standard and obsolete variants of industrial transceivers. For the AIP171 specifically, we maintain stock of current production units as well as compatible replacement options for discontinued models. The device’s modular design allows easy replacement of terminal blocks and communication cards, reducing downtime during maintenance.
