Function and Electrical Ratings/Requirements
Sources 5 VDC power for active devices
60 mA total current
Sources 15 VDC power for active devices
35 mA total current
Analog Input, Voltage Mode
Accepts a 0-10 VDC input signal.
10 VDC Maximum Input Voltage
Internal 75k ohm Pulldown
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.
Analog Input, Resistive Mode
Accepts 0-600k ohm input signal.
Internal 12 V, 15k ohm Pullup
Binary Input, Dry Contact Maintained Mode
1 s minimum pulse width (0.5 Hz at 50% duty cycle)
Internal 12 V, 15k ohm Pullup
Binary Input, Dry Contact Pulse Counter Mode
1 s minimum pulse width (0.5 Hz at 50% duty cycle)
Internal 12 V, 15k ohm Pullup
The input signal common for Universal IN terminals;
isolated from all other terminal commons.
Analog Output, Voltage Mode
Sources 0-10 VDC output voltage
1k ohm minimum load
10 VDC maximum output voltage
10 mA maximum output current
Binary Output Mode
24 V AC/DC FET
Connects OUT to OCOM when activated.
30 V AC/DC maximum output voltage
0.5 A maximum output current
40 mA minimum load current (hold current)
Analog Output, Current Mode
Sources 4-20 mA output current
External 300 ohm maximum load required
The output signal common; isolated from all other
terminal commons, including UO terminal commons.
