An interface module according to one aspect of the invention includes an interface and a local communication device. The interface, which is connected to a field device, receives a first wireless signal from the field device. The local communication device wirelessly transmits the first signal to a wireless module by first local communications. The local communication device receives, from the wireless module by second local communications, a second signal destined for the field device that is wirelessly transmitted from an external device and wirelessly received by the wireless device. The interface device outputs the second signal to the field device.

Wireless device and interface module

It is to realize a valve remote control apparatus capable of driving and controlling, with wireless signals, an air motor configuring an automatic switch to be attached to a manual valve. A valve remote control apparatus is configured to mechanically connect, to a manual operating portionof an existing manual valve, an output shaftof an air motorusing an air pressure as a drive source, and to remotely control the manual value. The valve remote control apparatus includes a solenoid valve (operating valve) operated by an operation signal transmitted and received wirelessly between a contact information terminal portionand a contact information operating portion. The air pressure for driving and rotating the air motoris supplied via the solenoid valve (operating valve).
