Series 39 - MasterINTERFACE - Relay Interface Modules (EMR or SSR) 2-6 A - FINDER
The Series 39 from Finder, known as MasterINTERFACE, represents a comprehensive range of relay interface modules designed for industrial automation and control panels. These modules integrate either an electromechanical relay (EMR) or a solid-state relay (SSR) with a rated current from 2 to 6 amperes, depending on the variant. They are typically available in 1-pole (1P) or 2-pole (2P) configurations, with coil voltages covering 12 VDC, 24 VDC, 24 VAC, 48 VDC, 110-125 VAC, and 230 VAC. The modules feature a compact, plug-in design with screw or spring-cage terminals, and include integrated LED indication and freewheeling diodes for coil suppression. They are designed for DIN rail mounting (EN 60715) and offer high switching capacity for their size, with mechanical endurance exceeding 10 million operations. The SSR versions provide silent, arc-free switching, ideal for high-frequency applications.
These interface modules are primarily used in industrial control cabinets, programmable logic controller (PLC) output interfacing, and signal isolation applications. They are common in sectors such as manufacturing automation, building management systems (BMS), process control, and energy distribution. Typical installations include motor control centers (MCCs), conveyor systems, HVAC controls, and safety circuits where reliable signal conversion between control logic and field devices is required. The modules also serve as buffer stages between low-level electronic signals and higher-power loads like contactors, solenoid valves, and indicator lamps.
The Series 39 category includes several subcategories based on relay type and function. Key article codes include: 39.01 (1P EMR, 6 A, with LED), 39.02 (2P EMR, 6 A, with LED), 39.31 (1P SSR, 2 A, DC switching), and 39.32 (2P SSR, 2 A, DC switching). The code structure typically follows the pattern: 39.XX, where the first two digits (39) denote the series, and the last two digits indicate the specific variant (e.g., .01 for 1P EMR, .02 for 2P EMR, .31 for 1P SSR). Accessories such as socket modules (e.g., 39.90) and marking tags are also available but not detailed here.
