Specifications Appendix A
Module OK status indicator 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 and open-circuit by bit reporting
Vendor I.D. code 1
Product type code 10
Product code 36
(1) 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, 30V DC input signal and 20V DC
potential above ground).
(2) For proper operation, both the plus and minus input terminals must be within ±10V DC of analog common.
(3) Open-circuit detection time is equal to the module scan time, which is based on the number of enabled
channels, and the filter frequency of each channel.
(4) Maximum current input is limited due to input impedance.

(1)
Repeatability is the ability of the input module to register the same reading in successive
measurements for the same input signal.
(2) Repeatability at any other temperature in the 0…60 °C (32…140 °F) range is the same as long as the
temperature is stable.
