Compact™ Combination Analog I/O Module 21
Publication 1769-IN057A-EN-P - July 2001
Output Specifications
Maximum Overload at Input
Terminals
(6)
Voltage Terminal: 20V continuous, 0.1 mA
Current Terminal: 32 mA continuous, +5V dc
Input Group to Bus Isolation 500V ac or 710V dc for 1 minute (qualification test)
30V ac/30V dc working voltage (IEC Class 2 reinforced insulation)
Channel Diagnostics Over-range by bit reporting
(1) The over-range flag will come on when the normal operating range is exceeded. The module will continue to convert the
analog input up to the maximum full scale range. The flag automatically resets when within the normal operating range.
(2) Rated working voltage is the maximum continuous voltage that can be applied at the input terminal, including the input
signal and the value that floats above ground potential (for example, 10V dc input signal and 20V dc potential above
ground).
(3) For proper operation, both the plus and minus input terminals must be within 0 to +10V dc of analog common.
(4) Includes offset, gain, non-linearity and repeatability error terms.
(5) Repeatability is the ability of the input module to register the same reading in successive measurements for the same input
signal.
(6) Damage may occur to the input circuit if this value is exceeded.
