Yokogawa to Release Multi-function Wireless Adaptor That Allows Wired Field Instruments to Function as ISA100 Wireless Devices

Yokogawa Electric Corporation announces that it will release a newly developed multi-function wireless adaptor on December 1. This adaptor enables wired devices that transmit/receive digital ON/OFF signals or receive 4-20 mA analog signals to function as ISA100 Wireless field wireless devices.

Plants use communication protocols, such as Foundation fieldbus, HART, Modbus, and Profibus, to facilitate the exchange of data. In addition, digital ON/OFF, 4-20 mA analog input, and other types of signals are used for a variety of purposes. This multi-function wireless adaptor has been developed with this latter category of signal types in mind. The mounting of this adaptor on a wired device that transmits/receives digital ON/OFF signals or receives 4-20 mA analog signals enables it to function as an ISA100 Wireless device. This increases the variety of devices that can be used with field wireless systems, and is expected to lead to a wider use of such systems in plant operations.

Signal types
For use with limit switches, solenoid valves, analog transmitters, and other device types, the adaptor has two channels for digital input signals that are used to monitor the ON/OFF state of devices, one channel for digital signals that output the ON/OFF state of devices, and one channel for receiving 4-20 mA analog process value signals from transmitters.

Environmental resistance
An all-weather model that is waterproof and dustproof and an explosion proof model that can be used in inflammable gas environments are expected to be released by the end of 2015.

Major target markets include such industries as oil & gas, LNG, refining, petrochemicals, chemicals, power, pulp and paper, pharmaceuticals, food, and iron and steel.
