INZ-TN2ZRE-E

(2) Analog output signal: Analog output connector (A/o)

Output signal : 4 to 20 mA DC or 0 to 1 V DC (selected when ordering)

Minus lines for the insulation and signal are common from the ground and inter-

nal circuit

Allowable load : 4 to 20 mA DC, 550Ω or less

0 to 1 V DC, 100kΩ or more

All the analog output signals of the instrument are not isolated individually. It is recommend-

ed to isolate the signals individually to eliminate the interference from the unnecessary signals

or the effect of external interference, especially leading the cable of more than 30 meters or to

outdoor.
