Universal Input
General Input Specifications
Input Sample Rate:
Four samples/second.
Digital Input Filter
time constant
0.0 (OFF), 0.5 to 100.0 seconds in 0.5 second increments.
Input Resolution:
14 bits approximately.
Always four times better than display resolution.
Input Impedance:
10V DC:
47KΩ
20mA DC:
5Ω
Other ranges:
Greater than 10M
resistive
Isolation:
Isolated from all outputs (except SSR driver). If single relay outputs are
connected to a hazardous voltage source, and the universal input is
connected to operator accessible circuits, supplementary insulation or
input grounding is required.
PV Offset:
Adjustable
input span.
PV Display:
Displays process variable up to 5% over and 5% under span.
