PicoSwitch radio controlled relay
The PicoSwitch radio controlled relay is a compact, wireless switching device that enables remote activation and deactivation of electrical circuits from distances up to 100 meters using RF (radio frequency) technology. Professional automation engineers, industrial technicians, and hobbyists use this device for remote equipment control in applications where hardwired connections are impractical or unsafe. It solves the critical problem of controlling high-power loads remotely without running long control cables, reducing installation complexity and improving operational safety in hazardous environments.
Product Overview
The PicoSwitch radio controlled relay operates on a transmitter-receiver architecture where the handheld RF transmitter sends coded signals to the receiver module, which activates internal relay contacts to switch connected loads. The device uses frequency-hopping spread spectrum (FHSS) technology to prevent signal interference and unauthorized activation, ensuring reliable operation in crowded RF environments. The relay contacts are rated for switching AC and DC loads with excellent isolation characteristics, making it suitable for both industrial and domestic applications requiring wireless remote control functionality.
What distinguishes the PicoSwitch from standard relays is its integrated RF receiver module with advanced signal processing, programmable address codes for multiple device control, and fail-safe design that defaults to a safe state during signal loss. The compact form factor allows easy integration into existing control panels, while the robust construction ensures long-term reliability in industrial settings. The device features low power consumption in standby mode and high switching speed, making it ideal for time-critical automation applications where response time matters.

How to Use
Installation begins by selecting the appropriate power supply variant (12V DC or 220V AC) matching your control panel configuration. Mount the receiver module on a standard DIN rail, ensuring proper grounding and connection of the relay contacts to the load circuit. Program the transmitter address codes by entering the receiver's programming mode through the dedicated push-button interface, then pair the transmitter unit by pressing the designated channel button. Test the RF signal strength using the receiver's LED indicator, which confirms successful pairing and adequate transmission range for your installation environment.
During operation, simply press the corresponding transmitter button to activate the relay contacts and switch the connected load. The receiver will acknowledge activation through a visual LED indicator and audible confirmation tone. For multi-channel systems, each button controls a separate relay independently, allowing simultaneous or sequential activation of multiple circuits. Always verify fail-safe operation by moving out of RF range to confirm the relay returns to its default safe state within 2-3 seconds, ensuring system integrity during signal loss scenarios.
Frequently Asked Questions
What is the maximum safe switching current for the PicoSwitch relay contacts?
The PicoSwitch relay contacts are rated for maximum continuous current of 10 amperes at 250V AC or 30V DC. For inductive loads like motors or solenoids, reduce the maximum current by 20-30% to account for inrush current spikes. Always verify your load current specifications against these ratings to prevent relay contact degradation and premature failure.
Can I operate multiple PicoSwitch units simultaneously without signal interference?
Yes, the frequency-hopping spread spectrum technology and programmable address codes allow independent operation of up to 16 different PicoSwitch units within the same RF environment. Each unit is assigned a unique address code during programming, preventing cross-triggering. However, operating more than 4 units simultaneously in close proximity may experience occasional signal collision; spacing transmitters at least 2 meters apart minimizes this issue.
How do I extend the transmission range beyond 100 meters?
The 100-meter range assumes line-of-sight propagation in open environments. To extend range, use external antenna extensions available as optional accessories, or install relay repeater modules that receive signals from distant transmitters and retransmit them to the primary receiver. For installations requiring ranges beyond 500 meters, consider upgrading to industrial-grade RF relay systems with higher transmit power ratings.
What happens if the transmitter battery dies while the relay is activated?
When transmitter battery voltage drops below operational threshold, the RF transmitter ceases signal transmission. The receiver module detects signal loss within 2-3 seconds and automatically defaults to its programmed safe state (typically de-energized). This fail-safe mechanism ensures equipment safety and prevents uncontrolled operation during power loss scenarios.
Is the PicoSwitch suitable for controlling AC inductive loads like motors?
Yes, the relay contacts are rated for AC inductive loads up to 10A at 250V. However, inductive loads generate back-EMF voltage spikes during switching, which can damage relay contacts over time. Install a suppression diode (for DC loads) or varistor (for AC loads) across the load terminals to protect the relay contacts and extend operational life significantly.
