Prekės informacija "LC-305 5-Channel AC Load Current Measurement Module, Modbus RTU"
LC-305 CR is a 5-channel AC load current measurement module for lighting control applications. Each channel accepts 0 to 5 A AC input at 50/60 Hz and reports the measured load current over a single RS-485 port, so a controller can track the state of each lamp circuit.
The module supports Modbus RTU or DCON on its serial port, with baud rates from 1200 to 115200 bps. Hardware-set addresses allow several modules to share one bus. Because the readings are updated every second, the data can be used to flag a failed lamp, spot a lamp that is starting to fade and needs replacing, or detect carbon build-up on relay contacts that may cause them to stick.
- Single-ended wiring, with accuracy of 3% of FSR
- Maximum load current of 10 A per module COM point and 5 A per single load at 25°C
- Powered from 10 to 30 VDC with reverse polarity protection
Applications
- Lighting control
- Lamp failure and fading detection
- Relay contact condition monitoring
- Load current monitoring on RS-485 networks
