Technical Specifications
Input voltage ranges (nominal):
+1 to +5V dc
0 to 5V dc
-5 to +5V dc
-10 to +10V dc
0 to +10V dc
Input current ranges (nominal):
+4 to +20mA
0 to +20mA
-20 to +20mA
Resolution:
12-bit binary
12 bits plus sign on bipolar ranges
Unscaled BCD and binary output to processor:
1000 to +409510 for polar ranges (0 to 5V, +1 to +5V, 0 to +20mA, and +4 to +20mA)
-409510 to 409510 for bipolar ranges (?5V, ?10V, ?20mA)
Internal scan rate:
12.5 ms for 8 differential inputs (no digital filtering) -add 2.12ms for filtering
25 ms for 16 single-ended input (no digital filtering) -add 4.24 for filtering
Environmental conditions:
Conductors:
The inputs are protected to 200V. However, if an input terminal's voltage exceeds +14.25V as referenced to module common, channel to channel crosstalk can cause invalid input readings and invalid underrange/overrange bits.
Only 8 volts can be placed directly across the input when configured in the current mode.
Refer to publication 1770-4.1, "Programmable Controller Wiring and Grounding Guidelines."
