Module OK LED On: module has power, has passed internal diagnostics,
and is communicating over the bus.
Flashing: external power failure.
Off: Any of the above is not true.
Channel Diagnostics Over- or under-range by bit reporting
output wire broken or load resistance high by bit
reporting
(1)
Output ripple is the amount a fixed output varies with time, assuming a constant load and temperature.
(2)
Repeatability is the ability of the output module to reproduce output readings when the same controller value is applied to it
consecutively, under the same conditions and in the same direction.
(3)
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).
