The 70L-OACA I/O Relay Modules is a general purpose output module with improved usability and efficiency for automated control applications. It provides a wide array of functionalities at the highest ratings, at a competitive cost. The AC output power stages are available in both AC and DC versions.

Application Field

The 70L-OACA I/O Relay Modules can be utilized in applications such as motor control, lighting control, home and office automation, pump control, outdoor and indoor lighting, heating and air-conditioning, traffic control, entertainment systems, and many more.

The use of I/O relay modules allows users to easily manage and control large amounts of input and output signals and data. The modules are designed to offer optimum performance under harsh operating conditions and to reduce operating costs by providing accurate and reliable outputs. They are also convenient for monitoring, diagnostic, and control of alarm systems, as well as for automation.

Working Principle

The 70L-OACA I/O Relay Modules consists of four independent, isolated power stages with built-in overload protection. It features real-time current sensing for fast response, advanced monitoring of the outputs to identify faults or brief overload conditions, as well as adjustable current limits and duty cycles for reliable operation. The AC outputs are capable of handling high-current loads, and the DC outputs provide highly-accurate low-current outputs with precise voltage control.

The AC outputs are designed to work with power sources ranging from 12 to 24VAC, and they can be used for applications requiring low-current control as well as higher powered ones. DC outputs have adjustable voltage and current values, so they can be used for more delicate applications such as controlling LED lighting or other low power applications. The AC (and DC) relay outputs are optically coupled for safety and isolation.

The 70L-OACA I/O Relay Modules provides a variety of features, including LED indicators for each operation status, auto-recovery after overload, reset-tested, and safe-floating mode for auto-detection of installation errors. The modules also support various communication protocols for integration with a variety of systems and applications.
