STANDARDS & APPROVALS
EU conformity:
EMC Directive 
  EMI EN 61000-6-4
  EMS EN 61000-6-2
RoHS Directive
  EN 50581

FUNCTIONS
OUTPUT HOLD or OUTPUT OFF
In normal conditions, the module outputs the signal from the preferred bus A.
When an error is detected, the output is switched to the data from the bus B.
Output Hold
If both are in error, the module holds the signal and stands by until one of the communications recovers.
Output OFF
If both are in error, the module outputs OFF signals and stands by until one of the communications recovers.
At the startup, it outputs OFF until the communication is established and normal data is received.

CAUTION
Use in combination with R3-NF2 or R3-NP1 is not available.
