OM-LDA-A801
The OM-LDA-A801 Positioning Leak Detector is designed to work seamlessly with OM-LDA-A601/5/10/15 leak sensing cables, point sensors, and normally open dry contact devices, such as float switches, optical probes with adapters, and limit switches, allowing for monitoring of sensing cables up to a length of 1000 meters. This leak detector is ideally suited for installation in standard (non-hazardous) environments and boasts three small LED indicator lights showing power, status, and communication activity, along with an SPDT relay for versatile connectivity. The OM-LDA-B801 Positioning Leak Detector can function as an autonomous leak detection alarm unit or can be integrated into a main control system (e.g., computer or control automation system) via straightforward shielded twisted pair RS-485 serial communication.
1. LED display power supply, leakage, cable failure and communication status.
2. digital tube display leakage location and power failure.
3. Can record 32 leak alarm records.
4. 12V DC power supply, non-polar access.
5. the relay output form is normally open and normally closed at the same time, can be freely selected.
6. a variety of communication baud rate is optional, through the software to set the module address and communication baud rate, no practical switch.
7. practical and reliable twisted pair serial RS-485 communication distance up to 1200 meters, standard industrial MODBUS protocol.
8. good anti-static, surge technology to ensure the reliable operation of the product.
9. can provide suitable for indoor independent installation or harsh outdoor installation conditions of the shell.
10. convenient 35mmDIN rail installation method.
11. Appearance size: 70*86*58mm, as shown below.
