Technical Overview of Omron G2R-2-SNDI-AP3 24VDC (S)

The Omron G2R-2-SNDI-AP3 24VDC (S) relay socket is a plug-in industrial relay designed for 24 VDC control panels and automation interface circuits. It combines DPDT switching, diode coil protection, LED indication, mechanical status visibility and AP3 contact characteristics in one compact relay format.

Technical Structure

This relay operates with a 24 VDC coil and provides a DPDT contact arrangement. With two changeover contact sets, the relay can switch two independent circuits from a single control signal. This is valuable in relay logic, PLC interface panels and industrial machine control systems.

The SNDI structure includes a built-in diode for coil surge suppression. In DC relay circuits, this feature helps reduce reverse voltage when the coil is turned off. The AP3 version is associated with gold-plated contact design, which can be useful where low-level signals or improved contact stability are required.

Visual Indication and Testing

The relay includes LED indication and a mechanical indicator. These features provide quick confirmation of relay state during inspection, startup or service work. A test button can also support controlled manual actuation during commissioning and diagnostics.

Where It Is Used

The Omron G2R-2-SNDI-AP3 24VDC (S) is suitable for PLC panels, interface relay circuits, signal switching, automation equipment, control cabinets and maintenance-focused electrical systems. Its plug-in structure reduces panel service time because the relay can be replaced without disturbing the wiring base. For additional Omron references, visit Omron product information.
