Radio remote control L09

wireless

Product Overview
The L09 wireless remote X‑ray exposure hand switch is an accessory designed for radiography systems. It is compatible with portable X‑ray units, mobile DR/X‑ray systems, C‑arm machines and RF X‑ray devices. The complete set includes a wireless transmitter, receiver, signal antenna and mounting bracket, and supports two independent exposure modes to meet varied clinical requirements.

Working Principle
The receiver accepts 9V–24V input and houses two independent relays labeled A and B. The transmitter provides two control keys: ON to trigger exposure and OFF to reset or perform an emergency stop.

Auto Exposure Mode
Pressing ON closes relay A and starts an adjustable delay timer (1–9 seconds). After the set delay, relay B closes to initiate the X‑ray exposure while relay A remains engaged for the timing cycle. On completion the unit emits intermittent beeps every second as an end‑of‑exposure indicator. Press OFF to stop the buzzer and reset the system. Pressing OFF during the delay cancels the pending exposure. This mode is suited for remote, long‑distance control to keep staff protected from radiation.

Manual Exposure Mode
Hold ON continuously to maintain exposure up to the preset 1–9 s range; release ON at any time to terminate exposure immediately. After exposure the buzzer will emit intermittent beeps; press OFF to mute and reset. This mode is intended for close‑range, on‑site radiography where the operator may need to halt exposure instantly.
