Product Details:
Each SDO module has voltage and current loopback circuitry coupled with
sophisticated online diagnostics that verify the operation of each output switch, the field circuit and the pres-ence of a load.
This design provides complete fault coverage without the need to influence the output signal.
The modules are called “supervised” because fault coverage is extended to include potential field problems.
In other words, the field circuit is super-vised by the SDO module so that the following field faults can be detected:
- Loss of power or blown fuse
- Open or missing load
- A field short resulting in the load being energized in error
- A shorted load in the de-energized state
