Check your device’s calibration certifi cate and user manual for the actual electrical input/
output requirements, as all instruments are custom confi gured to some extent.
NOTE: Pins 1, 9, and 10 are connected together inside of the device and are common
grounding points.
N/C = Not Connected/Open (can be used for custom pin assignments – please consult factory).
The following pin-out chart describes the safest and generally compatible arrangement when
connecting a non-Alicat DB15 wire to a DB15B equipped Alicat. Not all features may be
available between brands, but the common denominators are featured in our DB15 offerings,
along with some options for customization.
