A-4 Specifications
Input Channel Configuration via configuration software screen or the user program
(by writing a unique bit pattern into the module’s
configuration file). Refer to your controller manual to
determine if user program configuration is supported.
Module OK LED On: module has power, has passed internal diagnostics,
and is communicating over the bus.
Off: Any of the above is not true.
Channel Diagnostics Over or under range by bit reporting
Maximum Overload at Input
Terminals

(1)
The over- or under-range flag will come on when the normal operating range (over/under) 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 ±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 to the input circuit may occur if this value is exceeded.
(7)
If the optional 24V dc Class 2 power supply is used, the 24V dc current draw from the bus is 0 mA.
