Bosch Rexroth Hydraulics Analog Amplifier R902091800 Price in Bangladesh

Description

Product Name: Bosch Rexroth Hydraulics Analog Amplifier R902091800 Price in Bangladesh

Manufacturer: Bosch Rexroth

Product Overview

The Bosch Rexroth R902091800 (RA2-1) is an analog amplifier designed to actuate up to two proportional solenoids or two individual devices independently. It processes a specified control voltage input variable to provide a regulated electric current output for proportional solenoids. Furthermore, it incorporates adjustable time ramp functions ranging from 100 ms to 10 s to adapt output current changes smoothly. Additionally, it features comprehensive error detection, LED status indicators, and an IP65 protection rating when installed with a mating connector.

Key Features and Benefits

• Dual Proportional Output Control: Actuates up to two proportional solenoids or independent devices with separately adjustable minimum and maximum current limits via trimming potentiometers.

• Adjustable Time Ramps: Includes integrated time ramp functions with an adjustment range from 100 ms to 10 s for smooth output current adaptation.

• Robust Environmental Protection: Built in a plastic injection molding PA66 GF 35 case with IP65 weather resistance, shock resistance, and salt spray protection.

• Comprehensive Error Detection: Monitors power supply undervoltage and detects potentiometer wire breaks or short circuits.

• Additional Switching Capabilities: Provides a 1 A MOSFET switch output alongside dual PWM proportional solenoid outputs.
