PPM Technology i/fB
PPM Technology interface board (ifB)
- Visual LCD display output of current formaldehyde levels within the room
- Readings from the internal formaldemeter displayed on the screen
- Quick and easy solution for monitoring air quality
- Three modes of operation
The PPM Technology interface board (ifB) comes complete with a built in Formaldemeter unit which is designed to connect to third party systems. The interface board can be configured to give different voltage outputs; a 4–20mA current output and also give a relay alarm output.
There is a configuration menu available to allow the user to choose output type, operation mode, select output tests, sampling range and also calibrate the Formaldemeter. The menu also allows for the incorporated voltage-less relay to be triggered at various concentrations so that external equipment can be controlled.
Modes of operation
Various modes of operation are available to suit a whole array of uses, applications and situations. The ifB can be used in one of three sampling modes, depending on what best suits your needs. These are the polled mode, the continuous mode and the timed mode.
