Teledyne Gas & Flame Detection’s compact MX 32 unit is a low-profile control system that has been specially optimised for continuous gas monitoring applications.
The versatile solution is suitable for integration with a range of technologies, including 4mA-20mA, dry logic input and MODBUS RS485 signals from compatible detectors.
Features include:
- Analogue and digital controller
- One or two channels, up to eight detectors
- Fully scalable
- 5in LCD back-lit graphic display
- Five programmable events per detector
- Smart keys make embedded multi-language menus simple to use
