Connection with current-input type controllers
When the power to this controller is turned off, the current input circuit is cut off.
If multiple current-input type SDCs are connected in series and you want to turn
them on/off individually, convert them to voltage input by adding resistors (No.
81401325, sold separately) to the circuit.

Noise preventive measures
The power is taken from the single-phase instrumental power supply to consider
noise preventive measures.
If the noise from the power supply is large, an appropriate insulation transformer is
added to the power supply and an appropriate line filter is used.
(Azbil Corporation's line filter model No.: 81442557-001)
If the noise has fast rising edge, an appropriate CR filter is used.
(Azbil Corporation's CR filter model No.: 81446365-001)
Handling Precautions
After the noise preventive measures have been taken, do not bundle the
primary and secondary sides of the insulation transformer together or put
them in the same conduit or duct.
