➢
Positioner usually uses 4 ~ 20 mA DC. Minimum ampere of input signal of positioner is 3.2 mA but
maximum ampere of input signal should be 24 mA or under.
➢
Positioner with PTM options must be supplied with
9 ~ 28 V DC
separately.
➢
DO NOT connect Voltage source (9 ~ 28 V DC) to Input (4 ~ 20 mA DC) terminal (IN+, IN-)
as it will cause PCB failure.
➢
Positioner should be grounded.
➢
Please use twisted cable with conductor section are 1.25 mm
2
and that is suitable for 600 V
(complying with the conductor table of NEC Article 310.) The outer diameter of the cable should
be between 6.35 ~ 10 mm. Use shield wire to protect against electro-magnetic field and noise.
➢
Please do not install the cable near high noise equipment, such as high-capacity transformer or
