SET-1250
32Ch 4-20mA current sink card

Current sink simulation for 32 isolated channels

  • SET-1250
The SET-1250 4-20mA Current Sink Card provides current sink simulation for 32 isolated channels and supports an extended range of 0-24.6mA.

Each channel provides a disconnection relay and a short circuit MOSFET, by which open and short circuit faults can be simulated.

The short circuit MOSFET has an overcurrent protection with an integrated current limitation.

The desired simulation value and fault insertion can be set for each channel independently.

The SET-1250 provides both RTI API and SLSC API for configuring the outputs.
