SDM-CVO4 4 Channel Current/Voltage Output Module

The SDM-CVO4 is a synchronously addressed datalogger peripheral that outputs variable voltage or current signals under datalogger program control.

Each output can be set to 0-10 Vdc or 0-20 mA by the datalogger program (current outputs can also be scaled and limited to 4-20 mA). Typical applications include driving remote 'current-loop' display units, re-transmitting measured values to industrial control systems that have current or high voltage inputs, sending control signals to valve controllers and providing excitation voltages or currents to external sensors.



  • Expands datalogger analog output capability
  • Provides four independent current or voltage outputs
  • Supports a voltage output range of 0 to 10000 mV with a resolution of 2.5 mV
  • Supports a current output range of 0 to 20000 uA with a resolution of 5 uA
  • Generates a 0-20 mA current source using its own power supply
  • Conforms to EN55022-1:1998 and EN50082-1:1998
