Product short description:
- Transmitter, Loop, DC, or AC-Power
- AC Voltage or AC Current Input
- DC Voltage or DC Current Output
250T-AC, 350T-AC, 450T-AC: Loop, DC, or AC-Power Transmitter Description
These models convert sensor inputs to proportional process current or voltage output signals.
AC voltage transmitters accept direct voltage inputs. Current models include an external AC current sensor. This toroidal sensor outputs a safe DC milliamp signal which transmits accurately over long distances. Input span is a function of the primary turns placed on the sensor.
Models
250T: Loop-powered transmitter series
350T: DC-powered transmitter series
450T: AC-powered transmitter series
Features & Benefits
- Excellent accuracy and stability ensure reliable measurements in harsh industrial environments.
- External AC current sensor with DC mA output enables remote mounting of transmitter (for safe monitoring of the AC signal)
- AC current range is a function of sensor primary turns for easy rescaling in field
- Factory-calibrated AC current transmitter does not need recalibration
- RFI and EMI resistance minimize the effects of environmental noise.
- Compact, 1-inch wide housing uses less space.
- Low power consumption. (350T as low as 9mA).
- 1500V AC peak isolation (250V AC or 354V DC continuous) prevents ground loops.
250T: Input isolated from output/power
350T: Input isolated from output and power. Output and power share a common.
450T: 3-way isolation, input, output, and power circuits are isolated from each other. - Operating temperature range: -13 to 185°F (-25 to 85°C)
