Some ASO relays already require an external test. Selection must start from documented functions and the installation’s safety chain.
ASO 31-31 and 35-32 manuals establish the testing requirements for these relays. The European Commission explains the standards framework; it is not the source of this ASO-specific requirement.
ASO 31-31 manual · §6.3, p.27ASO 35-32 manual · §8.4, p.31The Machinery Regulation (EU) 2023/1230 generally applies from 20 January 2027. Article 52 provides transitional arrangements for products placed on the market under the Directive before that date and for certain certificates until their expiry.
Regulation 2023/1230 · Articles 51, 52 and 54Official corrigendum · 20 January 2027 dateAs of 25 October 2026, the Commission reports that a new list of harmonised standards under the Regulation is being prepared. References published under the Directive must not be automatically transferred to the new framework.
European Commission · preparation of the new listHarmonised standards are a voluntary route to demonstrating compliance: the presumption covers only the requirements actually addressed, with the applicable edition and restrictions. Legal safety requirements remain mandatory.
European Commission · role of harmonised standardsThe sources reviewed do not establish a new universal duty to self-test or replace every existing gate on that date. A substantial modification requires a separate assessment under the Regulation.
Single-channel DIN-rail relay for an 8.2 kΩ tactile device, with redundant output and fault diagnostics. Validate its configuration and safety chain for the installation.

Dual-channel enclosed relay for two 8.2 kΩ tactile circuits. Its manual describes a redundant, mutually monitoring architecture; connection and final protection follow the installation requirements.

For one 8.2 kΩ tactile device, with redundant output and fault diagnostics in a wall-mounted enclosure. Validate the reset functions and complete installation against the manual.

Two monitored tactile circuits and redundant safety outputs, for an 85–265 V AC or 24 V AC/DC supply. The manual distinguishes the relay ratings from those of the system with sensors.
View the product page →ASO manual · p. 22For the 42-622, the manual distinguishes the relay alone, stated as category 3 / PL e, from the described complete system with ASO sensors, stated as category 3 / PL d. The module PL must not be assigned to the entire installation.
ASO 42-622 manual · p. 25The 39-726 is not included in this highlighted selection: its manual states PL d in §3, page 17, then PL e in the §13 table, page 25. Manufacturer clarification is needed; selecting only the higher value would be misleading.

The Order of 21 December 1993 provides for visits at least every six months, adapted to use, and after a failure. Periodic inspection does not replace automatic testing of the control safety chain.
