Internal reference 0 to 5 V input*/External reference 0 to 20 mA input
•
External reference 0 to 5 V input/External reference 0 to 20 mA input
•
External reference 1 to 5 V input/External reference 4 to 20 mA input
* The internal reference 0 to 5 V is used when the 5 V output terminal voltage
(pin No. 20) of this controller is used as the reference.
• Analog output type/range selection (function setup C-06, C-09)
Output can be set either to instantaneous flow rate (PV) or flow set value (SP).
Furthermore, a voltage/current output range can be selected from (1) to (4)
shown below by key operation. Additionally, (1)/(2) or (3)/(4) can be changed
through the external 3-way switching input. (Combinations are switched
because of linkage with the analog input range selection.)
Instantaneous flow rate (PV) output Flow set value (SP) output
(1) 0 to 5 V output
(2) 1 to 5 V output
(3) 0 to 20 mA output
(4) 4 to 20 mA output
(1) 0 to 5 V output
(2) 1 to 5 V output
(3) 0 to 20 mA output
(4) 4 to 20 mA output
