Radio remote control C2UW series

wireless

The Wireless Bluetooth Hand Switch is a Bluetooth 4.0 full‑duplex remote hand switch designed for X‑ray machines, offering reliable wall‑penetrating connection and multi‑step control for exposure and collimator functions. The system comprises a transmitting handle and a compact receiving terminal with relay outputs that integrate with the original machine wiring.

Key features

• Full‑duplex mode using Bluetooth 4.0 protocol for reliable connection and good through‑wall performance.
• Battery/connection status indication: indicator light flashes when battery is weak or Bluetooth connection is poor.
• Designed around a two‑step, three‑key control mode suitable for X‑ray machine characteristics.
• Compact receiving end allowing hidden fixed or hanging installation.
• Receiving terminal provides three relay contact outputs and supports external voltage line connection without changing original machine working mode.
• Control mode can be customized according to customer requirements.

Components / Models

• Handle (transmitting terminal): C2UW-LP-I DA — uses three AAA (7#) alkaline batteries (recommended).
• Receiver (receiving terminal): C2UW-LU DA — receiving terminal with relay outputs for integration.

Power supply & consumption

• Handle (battery): Rated voltage 4.5V, allowable range 3V–4.5V.
• Receiver (external power): Rated voltage 5V–12V; typical current consumption 100mA; allowable DC range 4.5V–13V; maximum current 400mA.

Transmitting terminal (handle) functions

• Main switch 1st step: Ready.
• Main switch 2nd step: Exposure.
• Sub switch 3rd step: Control collimator.
• Blue light (on handle): Bluetooth indicator.
• Red light (on handle): Low voltage indicator.

Receiving terminal indicators and behavior

• LED Light 1 (Red): Power‑on indicator — lights when the receiving terminal circuit is powered.
• LED Light 2 (Blue): Bluetooth connection indicator — flashes = not connected; flashes quickly = connection in progress; off = connection successful and in low‑power state.
• LED Light 3 (Green): Main switch 1st step ON (SW1).
• LED Light 4 (Green): Main switch 2nd step ON (SW2).
• LED Light 5 (Green): Sub switch 3rd step ON (SW3).

Technical specification / Characteristics
