Mạch tín hiệu đầu ra tương tự IND331 Analog Output Option Board

Under Zero
When the source value drops below zero, the analog signal continues to decrease below 4mA. This continues until approximately 2.5mA. When the under zero display blanking point is reached, or the analog signal negative range is exceeded, the analog output immediately switches to 0 mA and remains there until the display is no longer blanked or the analog signal returns to within range. The under error output will also be turned on
Normal Range
The analog output will reflect the source value from 4mA (zero setting) to 20mA (high limit setting).
Over High Limit
When the source value exceeds the high limit, the analog signal continues to increase. This continues until approximately 21.5mA. When the display blanking point is reached, or the analog signal positive range is exceeded, the analog output immediately switches to approximately 24 mA and remains there until the weight display is no longer blanked or the analog signal returns to within range. The over error output will also be turned on.
