The NX-SIH400 is an ultra slim safety control relay from safety specialists, OMRON Industrial Automation. This unit is a Standard I/O relay with multiple-input and built-in circuits for soft logic functions.

The safety control relay is used to monitor the states of multiple emergency stop switches. It can also be used to detect other safety input switches such as guard switches, limit switches, light curtains, and others. This safety relay is suitable for applications where a high level of safety is essential.

The NX-SIH400 can be used as either an input only safety relay that can be used to detect the states of the emergency stop switch inputs, or as a complete safety relay when used in conjunction with an external safety relay module such as the NX-NEXJ-401. Even if the emergency stop input is not connected, the safety relay can be used to detect the states of the other inputs by using the built-in soft logic.

The safety control relay features all of the important safety features such as a printed circuit board of the control board with safety circuit pattern, built-in output contacts, built-in safety circuits, and built-in music output. It also has a selfdiagnostic circuit, and short-circuit protection circuit.

The NX-SIH400 can be used in a variety of applications such as controlling access into restricted areas, maintenance and production areas, and hazardous sites. Additionally, it can be used to control the operation of machines, presses, and other machinery. It can also be used to detect the presence of people.

The working principle of the safety control relay is quite simple. The system has a number of inputs and outputs. The inputs are connected to the emergency stop switches, guard switches, limit switches, light curtains, and other inputs. The outputs can be connected to auxiliary relays, alarms, and other device outputs. The built-in logic circuits process the inputs and if the input conditions are met then the output will be activated.

When the input conditions are not met then the output will become inactive. This is a fail-safe system and it is designed to shut the system down in the event of an emergency or hazardous situation. The working principle of the safety control relay is the same regardless of the type of inputs or outputs used.

The NX-SIH400 is an important tool for any application where a high level of safety is essential, such as in access control, machine guarding, production and maintenance areas, and hazardous sites. The built-in circuitry and logic enable the safety control relay to reliably detect the state of the input conditions, making it an effective and dependable safety control system.
