250T-FQ, 350T-FQ, 450T-FQ: 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
- Quartz crystal time-base design improves temperature performance
- Field-selectable time constants optimize output response time and ripple characteristics
- Selectable threshold circuits accept uni-polar/bipolar inputs (0V bipolar, 1.5V unipolar)
- Excitation/pull-up circuit adds flexibility
- 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)
