No. Each channel can be configured for current or
voltage but must be same range.

One count in the specification table is equal to one least significant bit of the analog data value (1 in 4096).
NOTE 1: Shields should be grounded at the signal source
NOTE 2: Unused channels should be connected to 0V or have current jumpers installed
More than one external power supply can be used (see channel 8)
A Series 217, 0.032A, fast-acting fuse is recommended for 4-20mA current loops.
If the power supply common of an external power supply is not connected to 0VDC on the module,
then the output of the external transmitter must be isolated. To avoid “ground loop” errors,
recommended 4-20mA transmitter types are:
2 or 3 wire:
4 wire:
Isolation between input signal and power supply.
Isolation between input signal, power supply and 4-20mA output.
1 channel per scan min., 8 per scan, max.
16 (X) input points (12 binary data bits, 3
active channel bits, 1 bit unused)
75mA
Removable (D4-16IOCON)
18-30VDC, 120mA, class 2
0.032 A, Series 217 fast-acting, current inputs
32° to 140°F (0 to 60°C)
± 50 ppm/°C maximum full scale (including
maximum offset change of 2 counts)
-4 to 158°F (-20 to 70°C)
