Replace the text by the following paragraphs:
This part of IEC 61010 specifies:
This part of IEC 61010 specifies particular safety requirements for industrial COMMUNICATION CIRCUITS and their INTERCONNECTION where equipment is intended to be installed in a process or discrete control environment.
NOTE - The equipment could be connected to an overall communication network.
These include COMMUNICATION CIRCUITS and INTERCONNECTIONS which are part of electrical test and measurement equipment or process control equipment, where these are intended to be used in an industrial environment.
Type of COMMUNICATION CIRCUITS covered:
NOTE - Any industrial process control equipment can have more than one COMMUNICATION CIRCUIT.
- COMMUNICATION CIRCUITS with COMMUNICATION PROTOCOLS below 50 V r.m.s., 70 V peak and 120 V DC, where the COMMUNICATION CIRCUIT is expected to be exposed to excessive transients in the end use installation.
