بریر ضد انفجار D1020S

Function:
1 or 2 channels I.S. mA analog output for 2 wire I/P Smart converters or valve
positioners, provides 3 port isolation (input/output/supply).

Name: 2 Ch, 0/4-20 mA I/P Isolating Driver, SIL 2

Type: Analog Output

Supply: 24 Vdc nom (20 to 30 Vdc)

Field device : I/P

Channels: 2

General Description:

The single and dual channel DIN Rail Isolating Driver, D1020S and D1020D, isolates and transfers a
4-20, 0-20 mA signal from a controller located in Safe Area to a load of up to 750 Ω in Hazardous
Area. It has a high output capacity of 15 V at 20 mA combined with a low drop across its input
terminals.
The circuit allows bi-directional communication signals, for Smart I/P. In the 4-20 mA input range, a
field open circuit reflects a high impedance to the control device output circuit.
