  • Page 44: Continuous Pulse Output

    When connecting the outputs to a customer system (e.g. PLC) galvanic separation of both systems is strongly recommended. Especially when using or connecting the EK280 to a hazardous area (hazardous area 1), an external isolation amplifier (permitted for use in hazardous areas) or usage of the FE260 is required.

  • Page 45: Isolating Outputs (Galvanic Isolation)

    EK280 Application Manual In particular, when connecting more than one output to a PLC, it must be taken into consideration that under normal operating conditions all 4 outputs have a common earth. Inputs on a PLC often have a common "plus" contact so that all outputs can be switched in parallel.

  • Page 46: Securing The Outputs

    (galvanic separation) Galvanic separation of the outputs is not relevant with regard to hazardous areas. If using the EK280 in hazardous area 1 then a permitted, external separator is required which is suitable for use in hazardous areas. An electrically isolated output only requires electricity provided that the output is active (switched on).
