DA-500 detects combustible or toxic gas leakage and displays the gas density on the built-in LCD.
20mA standard current output signal can be connected into the various controllers such as gas leakage warning devices (GMS-1000/2000), PLC, DDC, or MMR for individual or integrated gas monitoring system.
The various functions from artificial intelligence by built-in micro-processor offers more convenient & comprehensive gas monitoring environment with the easiest operation as well as the most extensive applications.
Digital Process : by built-in micro processor, various artificial intelligence functions enables more convenient, more accurate, and more efficient operation & maintenance.
Non-Intrusive Auto-Calibration With Magnetic Switch : by magnetic switch with digital processing auto-calibration, you can avoid a troublesome work of opening the sensor cover for operation or maintenance. This function is especially effective for the repair work in the explosion-proof area.
LCD Display With Back-Light : by real-time displaying the detection density on LCD, instant confirmation of density is possible. Also, auto back lighting enforces the readability of LCD even in dark area.
User programming menus for alarm, calibration, scale and so on.
4-20mA Transmitter : standard electric current output signal (4-20mA) for stable long distance(up to 2.5km) transmission.
Alarm Output : SPST relay contact(ALARM-1 & ALARM-2).
Communication Output : serial data output(option).
Explosion-Proof Approval : Ex d IIC T5
