4-20mA Signal Isolator DT236

The Acromag Model DT236 is a 4-20mA Signal Isolator. The DT230 Series Signal Conditioners provide two independent I/O Channels in a single unit. This model is a dual two-wire transmitter. It isolates and converts a DC current or low voltage inputs to a proportional 4-20mA control signal. Power is received from the output loop current or a DC supply when using a three-wire connection.

Firstly, high-voltage isolation separates all input and output circuits from each other. Plus, the isolation protects from surges, reduces noise, and eliminates ground loop errors. Set-up and calibration are fast and easy. Simply use a USB connection to your PC and Acromag’s Windows configuration software. Or the Android app sets up with mobile devices.

The DT236 is a versatile instrument. Designed to withstand harsh industrial environments and operate reliably across a wide temperature range with very low drift. They feature RFI, EMI, ESD, EFT, and surge protection plus low radiated emissions.

IMPORTANT: To prevent ground loop error between a grounded PC and a grounded input signal, Acromag strongly recommends Acromag’s USB-Isolator when configuring a DT230 Series transmitter.
