The newly developed multi-func- tion wireless adaptor enables wired devices that transmit or receive digital ON/OFF signals, or receive 4–20-mA analog signals, to function as ISA100 Wireless field devices. 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. The adapter can be used with switches, solenoid valves, and other device types that utilize digital ON/ OFF signals, and transmitters that utilize 4–20-mA analog input signals. 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. — Yokogawa Corp. of America, Newnan, Ga.
