GMF-MOD-ABK-01
Analog bus converter for GWA M 3.6 integration
For connecting conventional gas measuring sensors
with analog current output 4 – 20 mA to the GWA
M3.6. 1 conventional GMF can be connected to an
ABK. The current value is converted into a
digital bus signal and transmitted to the GWA
M3.6. Current values > 3.6 mA produce an offset
error. Supply voltage 24 V DC. With M16 cable
gland, IP 65 protection plastic housing.
