Modbus Light Sensor
Light and temperature sensor with voltage and current retransmission, and dual independent open-collector outputs for alarms. RS-485 Modbus Communication.
The KTA-275 is a light and temperature sensor housed in a convenient wall-mountable enclosure.
Values of light and/or temperature can be monitored via the analogue retransmission channels, with: 0 to 10 V, 0 to 20 mA, or 4 to 20 mA options. These outputs can be fully customised to suit your particular application.
In addition, two open-collector outputs are provided for additional control. These outputs can be configured to activate at user-definable thresholds of light or temperature.
All readings and settings can be monitored and changed using the Modbus protocol over 2-wire RS-485. A PC program is provided for this purpose.
