Why Choose the Finder 39.11.0.012.0073 MasterBASIC Relay Interface?
The Finder 39.11.0.012.0073 is an ultra-slim 6 A electromechanical relay interface module designed for industrial automation, PLC interfacing and electrical control systems. Part of the Finder Series 39 MasterINTERFACE range, this module combines a compact electromechanical relay with a DIN rail-mounted socket, providing a practical switching interface between low-voltage control signals and compatible electrical loads.
Featuring a 12 V AC/DC control input and a single changeover contact (1 CO / SPDT), the module enables compatible control equipment to switch AC or DC circuits through electrically isolated mechanical contacts. Its 6 A contact rating and silver nickel contact material make it suitable for a variety of industrial control and automation applications.
The Finder 39.11.0.012.0073 belongs to the MasterBASIC ATEX/HazLoc electromechanical relay range. It incorporates a Finder 34.51.7.012.0000 relay and a Finder 93.61.0.024.7 socket, providing a complete interface assembly with box-clamp screw terminals and standard DIN rail mounting. Its compact 6.2 mm width makes it particularly useful in control cabinets where installation space is limited.

Reliable Electromechanical Switching for Industrial Automation
The Finder 39.11.0.012.0073 provides a compact interface between low-voltage control equipment and compatible switched electrical circuits. When an appropriate 12 V AC/DC control signal is applied, the internal electromechanical relay energises, transferring its common contact from the normally closed terminal to the normally open terminal. Removing the control signal allows the relay to return to its normal position.
Its single-pole changeover contact provides flexibility for control signalling, circuit selection and load switching. Unlike a solid state relay, the electromechanical switching mechanism uses physical contacts, making it suitable for applications requiring a conventional changeover contact arrangement. The connected load must remain within the manufacturer's applicable switching ratings, particularly when controlling inductive or high-inrush equipment.
The module combines a Finder 34.51.7.012.0000 relay with a Finder 93.61.0.024.7 socket. This arrangement provides a replaceable relay within a compact DIN rail-mounted interface assembly, helping simplify installation, inspection and maintenance without requiring the entire socket assembly to be replaced when servicing the relay.
With a width of only 6.2 mm, the Finder 39.11.0.012.0073 can be installed alongside other compatible interface modules in densely populated control cabinets. Its box-clamp screw terminals provide practical wiring connections, while the LED indication assists with identifying the control status during commissioning and fault-finding.
The ATEX/HazLoc version is intended for installations where the applicable hazardous-location approvals are required. Suitability must be established using the product's current certification, permitted electrical ratings, temperature classification and installation instructions.
