Why Choose the Finder 093.68.14.1 MasterADAPTER for PLC Relay Interfaces?
The Finder 093.68.14.1 MasterADAPTER is a dedicated PLC interface accessory designed to simplify connections between programmable logic controllers and compatible Finder Series 39 MasterINTERFACE relay interface modules. It allows the A1/A2 control terminals of up to 8 MasterINTERFACE modules to be connected to PLC outputs through a single 14-pole ribbon cable, with a separate two-wire connection for the 24 V DC power supply.
Designed for industrial automation and electrical control panels, the Finder 093.68.14.1 reduces the complexity of connecting multiple relay interface modules to a PLC. Its 24 V DC nominal operating voltage, positive-switching control logic and integrated green power supply status LED make it a practical accessory for organised, maintainable control systems.
With a specified operating temperature range of −40 to +70 °C, a 1 A rated current per signal path and a minimum required supply power of 3 W, the MasterADAPTER is designed for professional industrial applications. The 093.68.14.1 is also identified by Finder as an ATEX version, making it relevant to installations requiring appropriately certified equipment.

Reliable Multi-Channel PLC Integration with Finder MasterINTERFACE
Industrial control systems frequently require multiple relay interface modules to connect programmable logic controllers to field devices, control circuits and machinery equipment. Connecting each interface individually can increase wiring complexity, particularly in densely populated electrical cabinets.
The Finder 093.68.14.1 MasterADAPTER addresses this requirement by allowing the control terminals of up to 8 compatible MasterINTERFACE modules to be connected through a 14-pole ribbon cable. This arrangement helps simplify the connection between the PLC output section and the associated relay interface modules.
The adapter operates from a nominal 24 V DC supply and uses positive-switching logic to the A1 terminals. Its separate two-wire power connection supports a straightforward supply arrangement, while the integrated green LED provides visible confirmation of power supply status.
Each signal path has a specified current rating of 1 A. This rating applies to the adapter's signal paths and should not be confused with the switching capacity of the connected relay interfaces. The electrical characteristics of the complete installation depend on the selected PLC outputs, relay modules, connected loads and supply arrangements.
Finder identifies the 093.68.14.1 as an ATEX version. Where the adapter is used in potentially explosive atmospheres, the complete installation must be assessed against the applicable hazardous-area classification, certificate conditions and installation requirements. The presence of an ATEX classification does not automatically make every connected component suitable for the same environment.
For installation and maintenance, the specified conductor capacities, 9.5 mm stripping length and 0.5 Nm terminal tightening torque should be observed. The correct ribbon cable pin assignment and compatibility with the intended Finder MasterINTERFACE modules must also be confirmed.
Typical Applications
- Connecting PLC outputs to multiple Finder Series 39 MasterINTERFACE modules.
- Industrial automation and PLC control panels.
- Multi-channel relay interface assemblies.
- Machinery and production line control systems.
- Process automation and industrial instrumentation.
- OEM machinery and electrical equipment manufacturing.
- Control cabinets requiring organised ribbon cable connections.
- Manufacturing and packaging equipment.
- Industrial equipment maintenance and control system upgrades.
- Appropriately assessed ATEX installations requiring compatible interface equipment.
