Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

ISO 23316-1:2022(E)
Introduction
0.1 General
Due to the requirements of modern agriculture, the precise control of implement functions is a key issue
in agricultural technology. The required precision is difficult to achieve with mechanical or hydraulic
devices; it is more efficient to provide control with electric and electronic means, i.e. electric power
and ISOBUS. The use of electric power allows implement manufacturers to offer farmers improved
implements that provide a higher degree of automation and navigation, resulting in greater precision,
better power distribution, and better controllability.
The purpose of the ISO 23316 series is to provide a design and application standard covering
implementation of electrical high-power interfaces operating at up to 700 V DC/480 V AC for
manufacturers of agricultural machinery.
The ISO 23316 series specifies the physical and logical interface requirements that provide
interoperability and cross compatibility for systems and equipment.
Conformance to the ISO23316 series means all applicable requirements from ISO 23316-1 to ISO 23316-7
are met.
It is permitted for partial systems or components to conform to the ISO 23316 series by applying all
applicable requirements, for example, for the plug, receptacle or inverters, on a tractor or implement.
NOTE If a DC-mode only HPI is provided, it is not necessary to conform with ISO 23316-4 which describes AC-
mode, as it is not applicable. If an AC-mode only HPI is provided, it is not necessary to conform with ISO 23316-5
which describes DC-mode, as it is not applicable.
The ISO 23316 series defines an interface between a power providing device (supply system) and a
power consuming device (consumer system), used within an automated electrified system in the
agricultural industry. This series deals with electrical, mechanical and bus communication objectives
and is used in conjunction with the relevant part of ISO 11783, which defines the ISOBUS. Figure 1
portrays the elements of typical equipment that involve the high-power interface.

Note 1 to entry: ISOBUS is a SAE J1939 based CAN communication bus system, usually used in agriculture and
forestry between, such as a tractor, as power supply and at least one implement as load. The communication bus
system consists at least of one tractor ECU and one implement ECU. One tractor ECU shall fulfil the functions
of a master controller. The tractor ECU (TECU) is a gateway between the ISOBUS and tractor internal bus(es)
including the attached controls; thus it exchanges communication objects between both buses, but fulfils also
further functions. On-board the implement at least one ECU (also known as Job Controller or Task Controller)
interconnects the ISOBUS with the implement application specific controls, optionally via implement internal
bus(es);
