the Zener barrier)
Allowable input voltage
: -0.5 to +12 V
DC voltage input
Input impedance: Min. 1 MΩ
Input bias current:
1 V range or less .............................Max. 1 μA (flows to the (+) terminal)
0 to 5 V, 1 to 5 V range ....................Max. 3.5 μA (flows to the (+) terminal)
0 to 10 V range ...............................Max. 7 μA (flows to the (+) terminal)
Burnout indication:
Downscale + AL02
However, the burnout cannot be detected in a range of 0 to 10V.
Allowable input voltage
:
-0.5 to +12 V
DC current input
Input impedance: Max. 100 Ω
Burnout indication:
Downscale + AL02
However, the burnout cannot be detected in a range of 0 to 20 mA.
Allowable input current
: Max. 30 mA
Allowable input voltage
: Max. 4 V (a higher voltage might cause input circuit failure)
* When the power to this controller is turned off, the current input circuit is cut off. If you connect
two or more current-input type controllers in series, change the current input to voltage input by
connecting a resistor (No. 81401325, sold separately). See Chapter 4.
