Q446 Signal Isolator
Brand: EurothermThe Q446 is a DIN rail mount, bridge or strain gauge input signal conditioner with 1,800 Vdc isolation between input, output and power.
The input can be set via DIP switches for any one of 11 V ranges from 10 mV to ±200 mV.
The output is linear to the input and can be set for either 0 to 5 V, 0 to 10 V, 0 to 1 mA or 4-20 mA, direct or reverse acting.
Features- Adjustable bridge excitation
- Field configurable input ranges
- Field configurable output ranges
- TouchCAL technology
- DIN rail mounting with IQRL
- Universal AC power 85 to 265 Vac
- SnapLoc plug-in terminals
