Series 38 Relay Interface Modules from Finder are compact, high-performance components designed for industrial control and automation systems. These modules integrate either electromechanical relays (EMR) or solid-state relays (SSR) with current ratings ranging from 0.1 A to 8 A, depending on the variant. Key technical specifications include coil voltages from 5 VDC to 110 VDC and 24 VAC to 230 VAC, with a typical switching power of up to 2000 VA for AC loads. The modules feature screw or spring-cage terminal connections, LED indication for coil status, and built-in freewheeling diodes for DC coils. The EMR versions offer mechanical endurance of up to 20 million operations, while SSR versions provide silent, arc-free switching ideal for high-frequency applications. The modules are available in 1-pole (1P) or 2-pole (2P) configurations, with optional plug-in bridges for commoning.
These relay interface modules are primarily used in programmable logic controller (PLC) output interfaces, signal isolation, and load switching within industrial control panels. They are common in sectors such as manufacturing automation, building management systems (BMS), HVAC controls, and process control. Typical installations include DIN-rail-mounted cabinets in factories, power distribution units, and machine control centers. The modules are also employed in railway signaling, elevator controls, and renewable energy systems like solar inverters, where reliable galvanic isolation is critical.
The Series 38 category includes several subcategories and key article codes. Main variants include the 38.11 (1-pole EMR, 6 A), 38.12 (2-pole EMR, 8 A), 38.21 (1-pole SSR, 2 A), and 38.22 (2-pole SSR, 0.1 A). The article code structure typically follows the pattern: 38.XX.0.XXX.XXXX, where the first two digits indicate the series, the next two the pole count and relay type, and the remaining digits specify coil voltage and terminal type. For example, 38.11.0.024.0000 denotes a 1-pole EMR with a 24 VDC coil and screw terminals. Accessories like socket modules (e.g., 38.91) and plug-in bridges (e.g., 38.92) are also available.
