Time Delay Relays provide a variety of functions for applications where time delays are required. The H3CRF8N AC2448/DC1248 Time Delay Relay provides two main functions: one-shot time action, instantaneous action, and cycle time action. It has three timing ranges, named “ON”, “OFF” and “reset”.

The H3CRF8N AC2448/DC1248 is primarily used in industrial automation control systems. It can be used as a controller in a control system, for example to control the motor, open/close a valve or switch, or set an alarm. It can also be used to provide time-delay events or alarms. It is commonly used in industrial production lines to control machines and equipment.

Its main application fields are in safety control, maintaining accurate time-delayed switchover or cyclical operations, providing instantaneous and/or accurate timed monitoring, and protective functions. The relay can be used to provide a range of timed operations, such as setting a time-delayed output, activating a specific output for a preset duration, activating multiple outputs in a specific sequence, and providing an output when an interrupt event occurs. It also has the capability to actuate a specific command after a predetermined time delay.

The working principle of the H3CRF8N AC2448/DC1248 is simple. It includes a timer circuit that uses a timer capacitor to generate a time delay. When a trigger is activated, a signal is sent to the timer. If the timer is not reset, the signal will remain until the time delay expires, triggering the output. The relay is equipped with adjustable timing ranges, which allow the user to set a specific time delay.

The H3CRF8N AC2448/DC1248 is a versatile time delay relay for industrial automation systems. Its various timing ranges, adjustable time delays, and multiple trigger inputs provide an efficient way to automate time-critical operations. It is well-suited for a range of applications, including safety, motor control, timing operations, and system protection.
