7.5: 20mA Output Card (20mAOS)
The 20mA card transmits a standardized 0-20 mA signal. This signal is linearly proportional to real-time quanti-
ties measured by the Shark ® 200 meter. The current sources need to be loop powered. The outputs are electrically
isolated from the main unit.
7.5.1: Specifications
The technical specifications at 25° C at 500Ω load are as follows:
Number of outputs:
Power consumption:
Signal output range:
Max. load impedance:
Hardware resolution:
Effective resolution:
Update rate per channel:
Output accuracy:
Load regulation:
Temperature coefficient
Isolation:
Maximum loop voltage:
Internal voltage drop:
Reset/Default output value:
The general specifications are as follows:
Operating temperature:
Storage temperature:
Relative air humidity:
EMC - Immunity interference:
Weight:
Dimensions (inch) W x H x L:
External connection:
7.5.2: Default Configuration:
The Shark ® 200 meter automatically recognizes the installed option card during Power Up. If you have not pro-
grammed a configuration for the card, the unit will default to the following outputs:
Channel 1
Channel 2
Channel 3
Channel 4
