Communication function The serial communication (RS232C/RS485) and contact I/Os (2 inputs and 3 outputs) are equipped as standard. Communication with the user’s equipment and system construction are possible, depending on the application. A 24 VDC output can be also provided, and is available for a flow switch (SMC’s PF3W, etc.). Applications There is a cooling tower, but high temperatures in summer or low (freezing) temperatures in winter make cooling water temperatures unstable. Cooling tower When・・・ There is no cooling tower. Tap water is being used. Even without a can be used to Cooling water at a consistent Dripping stops When・・・ There is a cooling tower, but high temperatures in summer or low (freezing) temperatures in winter make cooling water temperatures unstable. Cooling tower Less tap water used! When・・・ There is no cooling tower. Tap water is being used. Even without cooling tower, an air-cooled refrigerated chiller can be used to easily supply cooling water. Cooling water at a consistent temperature can be supplied regardless of the season. Dripping stops When・・・ There is a cooling tower, but high temperatures in summer or low (freezing) temperatures in winter make cooling water temperatures unstable.

Arc welding machine Cooling of the power source PC HRSH Remote operation switch Output 1 Output 2 Output 3 Input 1 Input 2 HRSH HRSH Remote signal I/O through serial communication The remote operation is enabled (to start and stop) through serial communication. Alarm and operation status (start, stop, etc.) signal output The alarm and status generated in the product are assigned to 3 output signals based on their contents, and can be output. Remote operation signal input One of the contact inputs is used for remote operation and the other is used for a flow switch to monitor the flow, and their warning outputs are taken in. Flow switch Low flow switch flow signal �� Output setting example Output 1: Temperature rise Output 2: Pressure rise Output 3: Operation status (start, stop, etc.) Ex.1 Ex.2 Ex.3 !Circulating fluid temperature setting !Start and stop !Circulating fluid discharge temperature !Circulating fluid discharge pressure !Run and stop status !Alarm information !Various setting information !Preparation completion status Power for flow switch (24 VDC) can be supplied from the thermo-chiller.
