Signal Isolators Smart Current Driver 9000Ex-31 / Ex-32 Supplier
SCB Industries is a reliable Signal Isolators Smart Current Driver 9000Ex-31 / Ex-32 Supplier, delivering high-performance and safety-certified solutions for industrial automation and hazardous area applications. We supply across Kolkata, West Bengal, Odisha, Bihar, Chhattisgarh, Assam, Gujarat, Pune, and Vapi, ensuring accurate signal transmission, electrical isolation, and dependable process control for diverse industries.
Description
9000Ex-31 and 9000Ex-32 are single-channel Smart Current Drivers that provide a galvanically isolated 4–20 mA signal to the hazardous area, corresponding to a 4–20 mA input signal from the safe area. They repeat the current signal in another floating circuit to drive a hazardous area load, using isolating transformers that provide galvanic isolation. The Smart Current Driver operates SMART I/P converters, electric valves, and positioners in hazardous areas. It features high output capacity combined with a low voltage drop across its input terminals.
9000Ex-31 and 9000Ex-32 are DIN-rail mount Smart Current Drivers with a width of 17.6 mm. These Smart Current Drivers are classified as associated apparatus. Connections to the safe area and hazardous area are located on opposite sides of the enclosure, using plugs and sockets. Additionally, hazardous area terminals are color-coded in blue for easy identification.
It restricts the transfer of energy from unspecified non-hazardous area apparatus to intrinsically safe circuits by limiting voltage and current. The apparatus also enables bi-directional signal communication between hazardous and non-hazardous areas through the connection of a HART communicator.
Process controllers with a readback facility can detect open or short circuits in the field wiring. In the event of a fault condition, the current drawn at the input terminals drops to a preset level. 9000Ex-31 having similar construction to the 9000Ex-32 variant with same input and output parameters but have a short circuit fault detection feature unlike 9000Ex-32.
