Y-Series

The redundancy module has two input channels which are completely independent from each other. Each control

circuit, auxiliary voltage source, or other circuitry in the module are designed separately for each input. The dual input

redundancy module can be considered as two single redundancy modules combined together in one housing. The only

common point is the circuit trace that ties the two separate circuits together at the output.

The MTBF figures below are for the entire dual input module. If the MTBF number of only one path is needed, simply

double the value from the table.

The redundancy module does not have electrolytic capacitors included. Therefore, the lifetime expectancy is extremely

high.

The Lifetime expectancy shown in the table indicates the minimum operating hours (service life).

**) MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicates reliability of a

device. It is the statistical representation of the likelihood of a unit to fail and does not necessarily represent the life of a product.

The MTBF figure is a statistical representation of the likelihood of a device to fail. A MTBF figure of e.g. 1 000 000h means that

statistically one unit will fail every 100 hours if 10 000 units are installed in the field. However, it can not be determined if the failed unit

has been running for 50 000h or only for 100h.
