250T-DC, 350T-DC, 450T-DC: Analog Transmitter; AC-, DC- or Loop-Powered, DIN Rail-Mount Description
These models convert sensor inputs to proportional process current or voltage output signals.
Input Ranges
DC voltage, ±100mV to ±100.0V DC
DC current, 0 to 20mA (10 ohm input load)
Output Ranges
DC current: 4 to 20mA
DC voltage: 0 to 5V or 0 to 10V
Power Requirements
250T: 12 to 50V DC @ 20mA (loop-powered)
350T: DC voltage source (see table below)
250T-DC, 350T-DC, 450T-DC: Analog Transmitter; AC-, DC- or Loop-Powered Features & Benefits
- Excellent accuracy and stability ensure reliable measurements in harsh industrial environments
- RFI and EMI resistance minimize the effects of environmental noise
- 90% span adjustment enables precise application calibration
- Compact, 1-inch wide housing uses less space for easier installation in control panels
- Low power consumption. 350T units operate on currents as low as 9mA to help prevent expensive upgrades to larger power supplies
- 1500V AC peak isolation (250V AC or 354V DC continuous) prevents ground loops
- 250T models: Input isolated from output/power
- 350T models: Input isolated from output and power. Output and power share a common
- 450T models: 3-way isolation. Input, output, and power circuits are isolated from each other
- Operating temperature range: -13 to 185°F (-25 to 85°C)
- DIN rail mount

Why Do I Need Electrical Isolation? - 8500988 (Log in to view the file)Why do we need signal isolation? Acromag is in the business of signal conditioning. We manufacture circuits that amplify, isolate, filter, and convert one signal form to another. Most of these circuits also provide electrical isolation. However, added isolation has a cost. Thus, sometimes customers either question their need for isolation or fail to recognize... -
