Описание (английский):

ISO 20401:2017 specifies the pin assignment for pneumatic directional control valves when used together with 8 mm and 12 mm diameter electrical round connectors according to IEC 60947-5-2. This definition is valid for connectors as shown in IEC 60947-5-2:2004, Figures D.2 and D.4, which are shown in Clause 4.

Overview

ISO 20401:2017 specifies standardized pin assignment for electrical round connectors used on pneumatic directional control valves. It applies to 8 mm and 12 mm diameter round plug connectors as defined in IEC 60947-5-2 (Figures D.2 and D.4). The standard ensures consistent wiring and electrical interface for solenoid-actuated valves in pneumatic fluid power systems, supporting interoperability, safe installation, and simplified maintenance.

Key Topics and Requirements

Scope: Pin assignment for directional control valves used with 8 mm and 12 mm electrical round connectors according to IEC 60947-5-2.

Connector types: Definitions refer specifically to the connector forms shown in IEC 60947-5-2 (male face views for 12 mm five-pin and 8 mm four-pin connectors).

Pin allocation (explicit):

Valves with a single solenoid:
- Pin 1: not used
- Pin 2: not used
- Pin 3: 0 V (solenoid)
- Pin 4: UB (supply voltage for solenoid)
Valves with double solenoids (one connector):
- Pin 1: not used
- Pin 2: UB for solenoid 12
- Pin 3: 0 V for solenoids
- Pin 4: UB for solenoid 14
Valves with double solenoids (two connectors):
- For both connectors:
  - Pin 1: not used
  - Pin 2: not used
  - Pin 3: 0 V
  - Pin 4: UB

Identification & symbols:

Port and control mechanism identification follows ISO 11727.
Graphical symbols used are in accordance with ISO 1219-1.

Normative references: ISO 5598 (vocabulary), IEC 60947-5-2 (proximity switch connectors), plus related ISO documents.

Applications and Who Uses It

Pneumatic valve manufacturers: implement standardized pinouts to ensure product compatibility.

OEMs and machine builders: design machines with consistent electrical interfaces for directional control valves.

System integrators and panel builders: reduce wiring errors and commissioning time through predictable connector pinning.

Maintenance and service engineers: quickly diagnose and replace solenoid valves without consulting device-specific wiring diagrams.

Safety and compliance teams: use the standard to demonstrate conformity with international switchgear and control interface practices.
