Ambient Operating Temperature Threshold: -20 to +55 degrees C
Relative Humidity Range Limits: 0% to 95% non-condensing
Country of Origin: Sweden
Module Net Mass: 0.4 kg (Approx. 0.88 lbs)
Physical Boundary Footprint (W x H x D): 120 mm x 100 mm x 30 mm
Industrial Application Scenarios
TheDSCA125 (57520001-GD)card is integrated into legacy Distributed Control Systems (DCS) driving continuous-process industries, such as paper and pulp mills, marine vessel power distribution setups, metal rolling foundries, and chemical batch plants. In these environments, the main MasterPiece or Advant Master controllers must orchestrate hundreds of remote field parameters simultaneously. The card acts as the high-capacity highway that funnels raw process inputs into the central processor and routes synchronized feedback loops out to the variable frequency drives and pneumatic actuators without inducing system lag.
