News — Dry Contact Triggered

Working Principle: This wireless remote control system (model 0020524) consists of a remote control (CB-2N) and a receiver (S1PU-DC). You can use this transmitter and the receiver to remotely control a device by the normally open contact of another device. Such as sensor automatic control system. You can connect a sensor to this transmitter and connect an AC or DC device to the receiver, then the device will automatically turn on or off through the sensor. When the sensor is activated, the transmitter automatically emits a wireless signal ON. When the receiver receives this wireless signal, it will activate its...

This receiver is a super long range remote switch. It is developed by LORA (Long Range) wireless communication technology, so it has ultra-long working distance, ultra-high receiving sensitivity, superior anti-interference ability, and smaller power consumption. It uses a transceiver chip to implement bidirectional communication, with a transmitter CC-2N to form a wireless control system. Its ideal working distance is up to 5 kilometers, which is an excellent device for remote control and long-distance communication. This transmitter CC-2N is a special long range remote control with normally open contact trigger, and it can be triggered by a dry contact instead of...
