GM INTERNATIONAL D1014D

Code : D1014D

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

Type : Analog Input

Supply : 10-30 Vdc

Description : 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

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

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

Function : 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

Features : 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.

SIL level : D1014D, according to IEC 61508, is suitable for applications up to level SIL 3
