DSI adapters are TEDS IEEE 1451.4 equipped sensor adapters that turn any of our DSUB9 universal analog input amplifiers into direct IEPE, charge, thermocouple, shunt, voltage, LVDT, or RTD input.
 
DSI - Dewesoft Smart Interface
Dewesoft DSI® adapters can be used with any Dewesoft data acquisition system input amplifier that uses a DSUB9 or DSUB15 input connector. This converts the amplifier's analog input capabilities to accept several types of signals:
 
voltage
current
resistance
IEPE/ICP®
strain gage
thermocouple
RTD (PTx)
LVDT

DSI-TH-J - Designed for type J thermocouples.
DSI-TH-K - Designed for type K thermocouples.
DSI-TH-T - Designed for type T thermocouples.
 
The DSI-TXx adapters include a TEDS sensor chip for automatic sensor detection and setting.
 
DSI Current Shunt Adapters
DSI current shunt adapters are adapters for direct current measurement. We offer different models of the DSI current  shunt adapters:
 
DSI-20mA - 20 mA current input adapter with 50 Ohm internal shunt, 0.01% accuracy when calibrated for sensors with 4 to 20 mA output.
DSIw-20mA - Waterproof version of the DSI-20mA adapter. It uses a 50 Ω shunt resistor with 0.01 % accuracy and 0.2 ppm/K temperature drift (0.05 ppm/K in the temperature range 0 °C to 60 °C). It is designed for sensing current from industrial sensors with 4-20 mA output in harsh environments. It is designed with a double DSUB9 adapter hood with IP67 protection.
DSI-5A - The new 5A current input adapter. Contains a 10 mΩ shunt resistor with 0.1% accuracy when calibrated. The new DSI-5A adapter has significant improvement is in temperature stability. The new shunt resistor has two times better temperature coefficient (now 15 ppm/K over the range -55 °C to +125 °C, before 30 ppm/K over the range -20 °C to +60 °C).
DSIi-10A - isolated current transducer with 10 A FS and < 0.5% accuracy with banana connector inputs.
DSIi-20A - isolated current transducer with 20 A FS and < 0.5% accuracy with banana connector inputs.
