Dual Channel Signal Converters

Acromag DT Series Dual Channel Signal Transmitters Reduce Costs and Save Space for Signal Isolation and Conversion.  These Process transmitters are ideal for signal conditioning of temperature, voltage, current, and resistance sensor inputs.

There is the choice of 2 wire (DT-200 Series) or 4 wire versions (DT-300 Series).

Dual Channel Signal Converters

Acromag offer dual channel signal converters for signal conditioning of temperature, voltage, current and resistance sensor inputs.

As a result, Acromag’s new DT Series signal conditioners are designed to offer a cost-effective space saving solution.  Therefore, interface a variety of process and sensor signals to your control systems.  As a result, each model supports several input ranges and can output a proportional 4-20mA, 0-10V or +/- 10V DC Signals.

Most importantly, they offer two independent signal conditioning channels in a 17.5mm wide module.  Firstly, you can achieve significant savings compared to using multiple single-channel transmitter units. So that a signal splitter mode lets one input drive both outputs. Also, Loop-powered 2-wire and externally-powered (6-32V DC) 4-wire versions are available.

For that reason, input options include process current, DC voltage, thermocouple, RTD, and resistance signal types with proportional process current or unipolar/bipolar voltage output. Also, a USB port simplifies setup on a PC with Windows software or on an Android mobile device using Acromag’s Agility app.

As a result, hazardous location approvals, high noise immunity, and a wide operating temperature range make DT Series transmitters ideal for use in harsh environments.
