Altech Corporation 3D2UL Industrial Relay Module

Altech Corporation 3D2UL Industrial Relay Module is a compact interface relay module from Altech’s lineup, designed to provide isolated, switchable connections in industrial control panels. It is intended for inclusion in DIN rail or panel-mounted installations, enabling expansion of control circuitry without redesigning the underlying logic. As part of a UL-recognized family of modules, the 3D2UL meets safety standards applicable to commercial and industrial automation environments, making it suitable for rugged control applications. The module serves as a reliable interface between low-power control logic and higher-current loads, allowing controllers such as PLCs to actuate relays that drive field devices while preserving electrical isolation and protecting sensitive circuitry. Typical applications include machine automation, process signaling, safety interlocks, and system controls where clean wiring and modular expansion are beneficial. The 3D2UL designation identifies it as a model within Altech’s modular interface offerings, designed to integrate with other Altech carriers and modules to form larger, scalable control subsystems. By leveraging Altech’s relay-module ecosystem, technicians can tailor panel layouts for easier maintenance and upgrade paths in OEM equipment, industrial cabinets, and test benches that require dependable relay switching in a compact form factor.
