Abstract: 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.

Abstract: A valve opening and closing system includes: a site/center switching manual valve; a manual valve for opening and closing operation; an opening/closing switching electric driving valve that opens and closes a manual valve and that nullifies the manual valve for opening and closing operation; a center wireless transmitter that accepts and transmits an operation instruction including an opening and closing operation instruction and a forced closing operation instruction; and a site wireless transmitter, and a contact signal converter, the site side valve control device transmits both of the opening and closing operation instruction and the forced closing operation instruction to the contact signal converter when the site/center switching manual valve is switched to the center control side, and interrupts the opening and closing operation instruction and transmits the forced closing operation instruction to the contact signal converter when the site/center switching manual valve is switched to on site.

Abstract: The purpose of the present invention is to enable use of a solenoid-type electromagnetic valve (120) in a valve driving device (10) that performs wireless communication. A contact signal converter (110) that converts an on-off contact signal to a control signal for operating a solenoid-type electromagnetic valve (120) comprises an explosion protection barrier (115) which restricts the current of the control signal to be no more than a maximum current established for safety regarding solenoid-type electromagnetic valves (120), and a group of batteries (111), the number of which can ensure a voltage at which the voltage supplied via the explosion protection barrier (115) surpasses the operating voltage of the solenoid-type electromagnetic valve (120).
