Same as IN
IN
n
Analog Input, Voltage Mode
Accepts a 0-10 VDC input signal.
10 VDC Maximum Input Voltage
Internal 75k ohm Pulldown
A
Analog Input, Current Mode
Accepts a 4-20 mA input signal.
Note:
For current sensing applications, the IOM2710
and IOM3710 Controllers do not provide a jumper to
close the current loop when the controller is powered off.
This option is available on IOM4710 Controllers only.
B
Analog Input, Resistive Mode
Accepts 0-600k ohm input signal.
Internal 12 V, 15k ohm Pullup
A
Binary Input, Dry Contact Maintained Mode
1 s minimum pulse width (0.5 Hz at 50% duty cycle)
