2 Ch, High integrity 4-20 mA TX Repeater Power Supply, SIL 3

10-30 Vdc

2

The D1014D provides two fully floating completely independent dc supply for energizing two conventional 2-wire 4-20mA Transmitters located in Hazardous Location, and repeats the current in floating circuits to drive two fully independent Safe Area loads. Suitable for application requiring SIL 3 level (according to IEC 61508 and IEC 61511).
The circuit allows bi-directional communication signals, for Hart Transmitters; the two channels are totally independent and do not have any common parts.

4-20 mA (15 V) floating supply and signal to Smart, or non Smart, two wire Tx.

4-20 mA source or sink or 1-5 V output signal totally isolated from Input and Supply.

2 channels I.S. analog input for 2 wire loop powered Hart Transmitters, provides 3 port isolation (input/output/supply) and current (source or sink) or voltage output signal.

High density with 2 fully independent channels.
Both sink or source output.
mA or V output.
650 Ohm output load capability.
High reliability with SIL 3 rating for each channel independently.
SIL 4 is achieved with the two channels in a 1oo2 architecture.
Isolation using only transformers.
10-30 Vdc power supply.

D1014D, according IEC 61508 & IEC 61511, is suitable for applications up to safety integrity level SIL 3 .
SIL 4 can be achieved by interconnecting the two channels in a 1oo2 architecture.
