High Voltage Input DC Power Transmitter TT338

The TT338 is a four-wire transmitter that isolates and converts high level DC voltage input into a proportional control signal. DC Current and Voltage Output are supported on a single model.

An optional DIN rail bus can deliver primary or redundant power to multiple units without wiring.

The Acromag TT338 is a High Voltage Input DC Power Transmitter.

Firstly, it features a multirange, ±15V, ±75V, or ±150V Input. Along with a Universal current/voltage output using a 12-32V DC Local/Bus power.

Secondly, setup and calibration is fast and easy. It has a convenient USB connection to PC and Acromag’s Windows configuration software. The Android App allows setup with mobile devices. Therefore, the high voltage isolation separates inputs, outputs and power from each other. Isolation protects from surges, reduces noise and eliminates ground loop errors. Also it is highly recommended to use a USB Isolator when configuring.

Finally the advanced signal processing capabilities and variable range of inputs/outputs of this instrument make it versatile. It can withstand hard industrial environments and operate across a wide temperature range. Features RFI, EMI, ESD, EFT and surge protection plus low radiated emissions.
