FestoVTUG Valve Terminal Assembly, 25-Pin Sub-D Multi-Pin Electrical Interface, 24 V DC

Product Description

What this part is

A Festo pneumatic valve terminal assembly fitted with the VAEM-L1-S-M1-25 electrical interface, the multi-pin end plate that collects every solenoid on a VTUG valve manifold onto a single 25-pin sub-D (D-sub) connector. One loom enters the terminal and 24 V DC switching is distributed internally to each valve. 2-242-95-0020 is the OEM assembly number. VAEM-L1-S-M1-25 is Festo’s designation for the interface itself, Festo part number 573445. The interface module carries no air; the pneumatic content of this listing is the VTUG valve terminal the interface is mounted on.

Decoding the order code

VAEM: Festo electrical interface for valve terminals. L1: interface form for the VTUG valve terminal family. S: sub-D style connection. M1: multi-pin (parallel) wiring rather than fieldbus. 25: 25 pins, up to 24 solenoid outputs plus common. The M1-25 variant is catalogued by Festo as V20. 2-242-95-0020: machine-builder or OEM assembly number.

What these specs mean in practice

Multi-pin means each solenoid is one discrete PLC output. There is no node address, no bus terminator and no gateway firmware revision to match, which is why multi-pin terminals remain popular for retrofits and for machines with a simple output card. The cost is copper: a 25-way loom runs back to the cabinet.

Solenoid supply is 24 V DC. Nothing on this interface takes mains voltage.

The interface is family-specific. It does not convert a VTUG terminal to fieldbus, and it does not fit the older CPV or VTUB platforms.

Published specifications

Type: pneumatic valve terminal assembly with multi-pin electrical interface. Electrical interface: VAEM-L1-S-M1-25 (Festo 573445). Connector: 25-pin sub-D, parallel / multi-pin wiring. Valve supply voltage: 24 V DC. Platform: Festo VTUG valve terminal. OEM assembly number: 2-242-95-0020. Origin: Germany.

Quantity and configuration

One assembly, new old stock. The mating 25-pin sub-D cable or loom is not included.

Mounting data

Pin-to-valve order is set by how the terminal was originally built rather than by a standard. Fitted valve slices and blanking plates follow the original machine’s circuit.

Interchange guidance

Festo 573445 is the bare interface. VAEM-L1-S-…-AP builds are the same interface family with a different connection form, related rather than substitutes. 2-242-95-0040 is the sibling OEM assembly number in this family. A fieldbus VTUG terminal (CPX / CTEU) uses an entirely different end plate.
