872C-A4N12-A2 PHOTOSWITCH Allen Bradley Box

The Allen-Bradley PhotoSwitch 872C-A4N12-A2 is a versatile and reliable opto-isolated relay module designed for use in various industrial automation applications. This product, which comes in a compact box, is manufactured by Rockwell Automation, a leading name in the industry.

The PhotoSwitch 872C-A4N12-A2 is an opto-isolated relay, which means that it uses light to transmit signals between the control circuit and the load circuit, ensuring electrical isolation between them. This feature is essential in applications where there is a need to separate high-voltage or high-current circuits from low-voltage control circuits to prevent electrical interference and ensure safety.

The module features four opto-isolated relay outputs, each rated for a maximum current of 1 A at 250VAC or 30VDC and a maximum voltage of 350VAC or 60VDC. These outputs can be used to control various loads such as motors, solenoids, or lights based on the input signal received.

The input signal to the module can be provided through either a normally open or a normally closed photoelectric sensor. The sensor detects the presence or absence of light and sends a signal to the corresponding opto-isolated relay output. This configuration makes the PhotoSwitch 872C-A4N12-A2 ideal for use in applications where the status of a machine or process needs to be monitored and controlled based on the presence or absence of light.

The module also comes with built-in diagnostics, which helps in identifying and troubleshooting any issues quickly. The diagnostics include output fault indicators, which illuminate when an output fails to operate or when there is a wiring issue.

The PhotoSwitch 872C-A4N12-A2 is designed for easy installation and integration into various automation systems. It requires a power supply of 100-240VAC, 50-60Hz, and has a compact size of 4.5 inches x 3 inches x 1.0 inches, making it suitable for use in control panels and other confined spaces.

The box that houses the PhotoSwitch 872C-A4N12-A2 includes the module, a mounting plate, and a wiring harness. The mounting plate allows for easy mounting of the module in a control panel, while the wiring harness simplifies the wiring process by providing pre-wired connections for power, inputs, and outputs.

Overall, the Allen-Bradley PhotoSwitch 872C-A4N12-A2 is a high-performance and reliable opto-isolated relay module that is perfect for use in various industrial automation applications where electrical isolation and opto-isolation are required. Its compact size, easy installation, and built-in diagnostics make it a popular choice among automation engineers and technicians.
