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
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
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.
