Intended to promote compatibility between transducers, recorders, indicators and data transmission systems of different manufacture which are being used in systems to control and monitor below ground activities and conditions.

This British Standard specifies requirements for apparatus incorporating signal circuits intended to be certified intrinsically safe for use in coal mines and which have inputs or outputs, as appropriate, in the form of d.c. voltage analogue signals (type V), or state signals (type S).

It specifies those electrical input and output characteristics of signal sources and signal loads necessary to achieve operational compatibility and also to simplify design for compliance with the relevant standards for intrinsic safety.

Section 1 specifies the general requirements applicable to both types of signals. Sections 2 and 3 contain specific requirements for voltage analogue and state signals respectively.

NOTE The titles of the publications referred to in this standard are listed on the inside back cover.
