Finder 39.10.0.024.9073 – 39 Series MasterINTERFACE – Relay Interface Modules – ATEX

Why Choose the Finder 39.10.0.024.9073 Solid State Relay Interface?

The Finder 39.10.0.024.9073 is an ultra-slim solid state relay (SSR) interface module designed for industrial automation, PLC output interfacing and electronic control systems. Part of the Finder Series 39 MasterINTERFACE range, it combines a solid state switching relay with a DIN rail-mounted interface socket, providing a compact solution for controlling DC electrical loads.

Featuring a 24 V AC/DC control input and a normally open DC solid state output, the module allows compatible low-voltage control signals to operate DC loads without mechanical switching contacts. Its solid state output is rated at 6 A, with a specified switching voltage range of 1.5–33 V DC, making it suitable for compatible industrial control and automation circuits.

The Finder 39.10.0.024.9073 belongs to the MasterBASIC HazLoc range and features a compact 6.2 mm-wide housing, screw-terminal connections and standard 35 mm DIN rail mounting. Its solid state construction eliminates mechanical contact wear and supports fast, silent switching in control cabinets where space, electrical isolation and dependable operation are important.

Reliable Solid State Switching for PLC and Industrial Automation

The Finder 39.10.0.024.9073 provides an electronic switching interface between compatible automation control signals and low-voltage DC loads. When the appropriate 24 V AC/DC input is applied, the normally open solid state output switches into its conducting state, allowing current to flow through the connected load. Removing the control signal returns the output to its non-conducting state.

Unlike conventional electromechanical relays, this interface module has no moving output contacts. This provides silent operation and avoids mechanical contact wear, making it suitable for automation systems requiring frequent or rapid switching. Its specified 0.2 ms operate time and 0.6 ms release time support responsive electronic control.

The module's 6 A DC output is intended for compatible loads operating within the specified voltage and current limits. Solid state outputs differ from mechanical contacts because they exhibit a small on-state voltage drop and off-state leakage current. These characteristics should be considered when selecting connected loads, particularly sensitive electronic equipment.

Its 6.2 mm-wide DIN rail construction makes the module useful in densely populated control cabinets. Screw terminals provide convenient field wiring, while optional jumper links allow compatible modules to share selected common connections, reducing wiring complexity in multi-channel automation assemblies.

The HazLoc-rated design supports suitable industrial installations subject to the applicable certification, enclosure and temperature requirements. Output current must be derated where necessary, particularly at elevated ambient temperatures or when operating under hazardous-location approval conditions.
