| Part Number: | UF20 | - | 4 | RTD |
|---|---|---|---|---|
| Explanation: |
Platform UF20 - UF20 I/O platform |
Inputs 4 - 4 input channels; fixed for this model |
Function RTD - Resistance temperature measurement; this breakdown covers UF20-4RTD only |
The UF20-4RTD accepts four resistance temperature detector inputs and transfers eight bytes of process data. It supports two-, three- and four-wire sensor connections, magnetic isolation and individual upper/lower process alarms for each channel.
