Block diagram
Base block diagram of the TRION-1820-POWER-4 module:
The TRION-1820-POWER-4 is an ultra-compact, 4-phase power data acquisition module with fl exible current
inputs for use in any DEWE2-chassis.
Voltage input:
Fast sampling, high bandwidth and minimum capacity to earth are just a few outstanding performance
qualities of the high voltage inputs. The high input impedance allowes high continous voltage levels with a
very low temperature drift. Although small outline, the safety category is on a very high level (CAT III 1000V).
Current input:
The TRION-1820-POWER-4 has 4 highly fl exible current inputs. The 4 slots can be populated with three
different direct current measurement modules or with a SUBD-9 module to connect almost any kind of
current transducer. Alternatively, this connector can also be used to measure any auxiliary ±10 V signal (e.g.
such as windspeed or water fl ow)
