KST2.4S/KSR2.4

KST2.4S/KSR2.4

Product catalog summary
General Parameters
The document describes the CRC-16 error detection mechanism with a Hamming distance of 6, ensuring reliable transmission of switching signals. Frequency hopping is used to minimize interference in the 2.4 GHz band, allowing multiple operations in the same area without channel management. Communication with the NK-2.4Y telecommand radio module is supported.

Applications
The KST2.4S and KSR2.4 telecommand units can transmit and receive up to 6 switching signals in the 2.4 GHz band. They feature 6 inputs (KST2.4S) and 6 outputs (KSR2.4) with three output operation modes: One-shot, Toggle, and Momentary. The units include a wiring harness for easy interfacing with user equipment and conform to FCC and ARIB standards.

Features
The units operate in the 2.4 GHz band and include a LINK LED for monitoring communication status. They support a wide operating voltage range of 6 to 24 V and are suitable for remote control applications such as motor-operated equipment control and sensor monitoring systems.

Specifications
  • KST2.4S: 6 inputs, DC 6 to 35 V input voltage, 30 mA max supply current.
  • KSR2.4: 6 outputs, DC 35 V, 200 mA max output relay, 80 mA max supply current (all outputs ON, no load).
Both units have a communication range of 100 m (line of sight) and operate in half-duplex mode for acknowledgment purposes. The frequency range is 2403 to 2479 MHz with a communication bit rate of 250 kbps. The operating temperature range is -20 to +60°C, and the dimensions are 55 x 45 x 12.5 mm with a weight of 26 g.

KST2.4S/KSR2.4-1

The KST2.4S and KSR2.4 are telecommand units that allow the transmission and reception of upto 6 switching signals in the 2.4 GHz band. The CRC-16 error detection achieving a Hamming distance of 6 allowing for reliable switching signal transmission. Frequency hopping minimises interference from other radio systems on the 2.4 GHz band. There is no need to manage any channels and multiple operation in the same area is possible. In addition, communication with separate NK-2.4Y telecommand radio module is possible. Both KST2.4S and KSR2.4 display a LINK LED allowing the user to monitor communication status. The units have a wide operating voltage range of 6 to 24 V. 6 inputs (KST2.4S) / 6 outputs (KSR2.4) 3 output operation modes (One-shot, Toggle, Momentary) 1:1 communication with KST2.4S and KSR2.4 Includes a wiring harness to allow easy interface to user equipment.
