November 25, 2014 - Yokogawa Electric released an unnamed multi-function wireless adaptor that 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.
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.
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.
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.
