5.2.1 Switching amplifier

For operation of the limit switches, switching

amplifiers must be connected in the output

circuit. To ensure the operating reliability of

the positioner, the amplifiers should comply

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.

For applications in safe areas (non-hazardous

areas), limit switches can be directly intercon-

nected to the binary input of the PLC in accor-

dance with IEC 61131. This applies to the

standard operating range for digital inputs ac-

cording to Clause 5.2.1.2 of IEC 61131-2

with the rated voltage of 24 V DC.
