ABB SC510 3BSE003832R1 Distributor Module

SC510 3BSE003832R1 is a two-wire 4-20mA signal loop type isolation distributor with energy-saving, safety and explosion-proof functions. The distributor can distribute 16V~21.5V for two-wire sensors, which is convenient for some two-wire passive sensors’ power supply, signal measurement, remote transmission and other functions. The output of the distributor is designed for a two-wire power supply circuit (field explosion-proof function) with 24VDC and sampling resistor (load resistor) in series, which is compatible with the analog input/output control ports of commonly used analog input/output interface boards (upper and lower computer), PLC, DCS or other data acquisition equipment.

SC510 3BSE003832R1 in use, the input side of the external sensor on the power supply and signal is coupled from the output side of the 4-20mA distributor module, the electrical signal can be used with a PLC, DCS, industrial control machine to control, when the need to collect data to the sensor to add power, do not need to shut down the power supply and the signal, so as to realize the energy-saving, explosion-proof function, you can Realize on-site multi-point data acquisition and control, but also to extend the service life of the sensor.

The SC510 3BSE003832R1 controls the accuracy and linearity of linear transmission of analog signals through comparative regulation and feedback amplification circuits, without the need for a separate power supply, and adopts a two-wire distribution loop output method. The IC contains internal current signal modulation and demodulation circuits, signal coupling and isolation conversion circuits. The very small input equivalent resistance enables the IC to capture signal voltages from the sensor circuit over a wide range (7.5-32V) to meet the needs of users for long-distance, distortion-free transmission of signals without the need for an external auxiliary power supply.
