Remote signal I/O through
serial communication
Remote operation is enabled (to start and stop
operation) through serial communication.
Alarm and operation status
(start, stop, etc.) signal output
The alarm and status generated in the product can be
output.
Remote operation signal input
One of the contact inputs is used for remote operation
and the other is used to monitor the flow of a flow
switch. This is where their alarm outputs are taken in.

Output examples
Output 1 : Operation status (start, stop, etc.)
Output 2 : Outputted when alarm
“FLT (operation stopped)” is generated
Output 3 : Outputted when alarm
“WRN (operation continues)” is generated
Outputs 4 to 6 : Assigned for specified type of signals

Power for flow switches (24 VDC) can be
supplied by the thermo-chiller.
Serial communication (RS232C/RS485), contact I/Os (3 inputs and
6 outputs), and analog output (2 outputs) are equipped as standard.
This allows for communication with the user’s equipment and system
construction, depending on the application. A 24 VDC output can be also
provided and is available for use with flow switches (SMC’s PF3W, etc.).
