5.2.1 Switching amplifiers
For operation of the limit switches, switching
amplifiers must be connected in the output
circuit. To ensure the operational reliability
of the positioner, the amplifiers should com-
ply with the limit values of the output circuits
conforming to EN 60947-5-6.
If the positioner is to be installed in hazard-
ous areas, the relevant regulations must be
observed.
