The Micro 4000 from AmpControl will accept inputs from any sensor/transmitter combination that will give a 4-20mA output. This versatile unit will also accept inputs directly from AmpControl's range of oxygen and combustible sensors along with two wire contact input devices.
Accpeing inputs from any sensor/transmitter combination that give a 4-20mA output the Micro 4000 also accepts inputs directly from Ampcontrol's range of combustible gas sensors, oxygen sensors and two wire contact input devices.
This controller is an essential componed for any carpark gas detection monitoring system. If you want to control when and for how long your carpark exhaust fans operate the Mirco 4000 will suit your application.
