Rockwell Automation 1769-IF4XOF2 Compact Combination Analog Module - Manual (Page 9)

Compact™ Combination Analog I/O Module 9
Publication 1769-IN057A-EN-P - July 2001
•
Voltage outputs (Vout 0+ and Vout 1+) of the 1769-IF4XOF2 module are
referenced to ANLG COM. Load resistance for a voltage output channel must
be equal to or greater than 1K
Ω
.
•
Current outputs (Iout 0+ and Iout 1+) of the 1769-IF4XOF2 module source
current that returns to ANLG COM. Load resistance for a current output
channel must remain between 0 and 300
Ω
.
•
Voltages on Vin+, V/Iin-, and Iin+ of the 1769-IF4XOF2 module must be
within 0 to +10V dc of analog common.
Wiring Differential Inputs
ATTENTION
!
Be careful when stripping wires. Wire fragments that fall into
a module could cause damage at power up. Once wiring is
complete, ensure the module is free of all metal fragments.
