KSD1420

Time Delay Relays (TDRs) are commonly used in a wide variety of applications. The KSD1420 is one such type of TDR that automatically opens and closes a switch, as necessary, at a specified interval. It is capable of controlling both AC and DC circuits, and its design is based on the on-off action principle.

The KSD1420 is designed for use with contactors and motor starters that require a time delay for controlling the motor start and stop. The relays are installed onto the contactors and motor starters by connecting the two terminals of the the KSD1420 to the contact terminals. The relay then monitors the start/stop commands from the contactor/motor starter and activates the circuit at the predetermined interval.

When the contactor energizes, the relay will close the circuit between the two contacts. This connection allows current to flow, which in turn causes the relay to energize, resulting in a specific amount of time delay. The time delay is determined by the position of the timing pot in the relay. The pot is adjustable between 10 milliseconds and 800 seconds and depending on the timing pot setting, its will stop the operation after that amount of time.

The KSD1420 is designed for reliable operation in both AC and DC circuits. It is built with heavy-duty toggle switches, heat-resistant copper alloy contacts, and a programmable "start/stop" button. In addition to the adjustable timing pot, the relay also features a manual-reset switch and a red indicator light for easier visual identification of the operating cycle. This feature also helps in case of power failure, as the relay will remain in the same position regardless of power interruption.

This time delay relays can also be controlled remotely, with a PC or other external devices, thanks to its on-board signal input and output terminal. This terminal simplifies the connection to external control systems, allowing for more efficient and reliable operation. The KSD1420 also includes a convenient terminal block for wiring to the control system, as well as a convenient test button for manual testing of the relay.

The KSD1420 is an ideal solution for applications that require precise timing and repetitive control of AC and DC circuits. It is easy to use, reliable, and cost-effective, making it a great choice for a wide range of industrial applications. It is also capable of delivering consistent performance in environments with extreme temperatures and vibration, making it an ideal choice for challenging industrial settings.
