MTL4644 temperature convert

The MTL4644 provides fully-floating dc supplies for energising two conventional 2-wire or 3-wire 4/20mA or HART transmitters, and

repeats the current in other circuits to drive two loads. For smart transmitters, the unit allows bi-directional transmission of digital

communication signals superimposed on the 4/20mA loop current.Alternatively, the MTL4644S acts as a current sink rather than driving a current into the load.

Number of channels:Two

Temperature drift:< 0.8µA/°C

Response time:Settles to within 10% of final value within 50µs

Communications supported:HART (terminals 1 & 2 and 4 & 5 only)

LED indicator:Green: power indication

Maximum current consumption (with 20mA signals):100mA at 24V dc
