Series 4C relay interface modules from FINDER are compact electromechanical switching devices designed for industrial control panels and automation systems. These modules integrate a relay coil and contact set within a single housing, typically available with 8 A or 16 A rated current, and coil voltages from 12 VDC to 230 VAC. The 4C series offers both 1-pole (1P) and 2-pole (2P) contact configurations, with silver-tin oxide (AgSnO2) contacts ensuring reliable switching under resistive and inductive loads. The modules feature a screw or spring-cage connection system, LED indication for coil status, and freewheeling diode protection for DC coils. They are designed for DIN rail mounting, with a width of 15.8 mm per module, and provide galvanic isolation between coil and contacts up to 4 kV. The 4C series is known for its high mechanical endurance (up to 30 million operations) and electrical life (up to 100,000 cycles at rated load), making them suitable for demanding industrial environments.
These relay interface modules are primarily used in industrial automation, building management systems, and process control applications. They are commonly installed in control cabinets, PLC output stages, motor control centers, and HVAC systems. The modules serve as signal amplifiers, isolating low-level control signals from high-power loads, and are ideal for switching solenoids, contactors, small motors, and indicator lights. They are also employed in safety circuits, emergency stop systems, and remote monitoring stations where reliable switching and galvanic isolation are critical. The compact form factor allows for high-density mounting in space-constrained panels, while the LED indication simplifies troubleshooting and maintenance.
The main subcategories within the FINDER Series 4C include the 4C.1 (8 A, 1-pole) and 4C.2 (16 A, 2-pole) modules. Key article codes are 4C.1.12.230.0000 (8 A, 1P, 230 VAC coil) and 4C.2.16.024.0000 (16 A, 2P, 24 VDC coil). The code structure follows: 4C.X.Y.ZZZ.WWWW, where X indicates poles (1 or 2), Y is rated current (08 for 8 A, 16 for 16 A), ZZZ is coil voltage (024 for 24 V, 230 for 230 V), and WWWW is a variant suffix for connection type or options. Other popular variants include 4C.1.08.024.0000 (8 A, 1P, 24 VDC) and 4C.2.16.230.0000 (16 A, 2P, 230 VAC). These modules are available with either screw or spring-cage terminals, and some versions include integrated protection diodes or RC snubbers.
