ایزولاتور بریر D1020D مارک GM INTERNATIONAL

توضیحات محصول

CODE : D1020D

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

Description: The dual channel DIN-Rail Isolating Driver, 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.

Hazardous area: 4-20 mA/0-20 mA and Smart Signal to I/P Converters, Electrovalve Actuators and Displays.

Safe area: Bus powered 4-20 mA/0-20 mA Signal from DCS, PLC or other control devices. Smart compatible.

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

Features: • 2 fully independent channels.
• Output to Zone 0 (Zone 20), Division 1, installation in Zone 2, Division 2.
• 4-20 or 0-20 mA Input, Output Signal.
• Wide Band Smart Communication, Hart compatible.
• Field open circuit detection.
• High Accuracy.
• Three port isolation, Input/Output/Supply.
• High Reliability, SMD components.
• High Density, two channels per unit.
• Simplified installation using standard DIN Rail and plug-in terminal blocks.
• 250 Vrms (Um) max. voltage allowed to the instruments associated with the barrier.

SIL level: SIL 2
