DA-750 detects leakage of various toxic or combustible gases by suction type gas sampling method using built-in micro pump.
The standard current output signal, 4-20mA, can be connected into various controllers such as gas alarming devices (GMS-1000/1500/2000), PLC, DDC, or MMR for construction of individual or integrated gas monitoring system.
RS-485 communication signal provides relay contact output for alarm signal.
DC 4-20mA standard output signal enables stable long distance signal transmission up to 2.5km.
Auto-Suction Type : built-in micro pump suctions leaked gas where diffusion type gas sampling method can not work.
Digital Process : various artificial intelligence functions by built-in micro processor offers more convenient operation & maintenance.
LCD Display with Back-Light : instant confirmation of the detected density displayed on built-in LCD is available even in dark area by auto back-light.
Isolation Circuit : built-in isolation circuit effectively protects against electric noise and secures sensor output signal.
Signal-Output : various output signals such as DC 4-20mA, 2 step-relay contact, and RS-485, can be connected to various controllers.
