Interface BSC4A Multi-Channel Analog Output Bridge Amplifier

BSC4A Quickstart Guide

Product Information

The BSC4A is a product with multiple pages of a quickstart guide. It is essential to read the entire guide before making any connections or powering the BSC4A. The product offers fixed gain settings for amplifier channels and is not adjustable for specific load cell output signals. This may result in the amplifier output being less than the nominal 10V or 20mA at the load cell full scale.

Product Usage Instructions

1. Before starting, make sure to read the entire BSC4A Quickstart Guide.
2. Familiarize yourself with the product description and available options.
3. Take note of the caution mentioned in the guide, emphasizing the importance of reading the entire guide before making any connections or powering the BSC4A.
4. Follow the instructions provided in the “Connections” section of the guide (pages 4, 5, and 6) to establish the necessary connections for the BSC4A.
5. Keep in mind that the amplifier channels have fixed gain settings and are not adjustable for specific load cell output signals. This means that the amplifier output may be less than the nominal 10V or 20mA at load cell full scale.

Introduction

• The BSC4A Amplifier takes up to 4 Independent Inputs and turns those signals into an analog output.
• ±10V and 4-20mA
• 4 independent channels
• For use with model 3AXX series 3-axis load cells or multiple load cells
• Can be used with up to any 4 standard load cells (with mV/V output)
• Inputs for Strain gage / 0–10 V /PT1000
• Measurement ranges 2 mV/V / 10 mV/V
• 8 digital inputs/outputs
• Data rate 0 Hz–500Hz

Description

This 4-channel measuring amplifier for sensors with strain gauges is equipped with a USB interface. The voltage is supplied via the USB port at the back of the measuring amplifier. The measuring amplifier can be delivered with an SUB- D37 connection or with 4x M12 ports. The measuring amplifier has eight digital inputs and outputs. On the backside SubD25 socket, strain gauge full-bridges and half-bridges 120 Ohm up to 1 kOhm as well as PT1000 temperature sensors and 1000 Ohm single grid strain gages or voltages 0-5V can be connected.

Options
±10V and 4-20mA output, up to 10 mV/V input, 37-pin input connector or 4 each M12 connectors and includes power supply.

Caution : Please read this entire guide before making any connections or powering the BSC4A.

Connections

Wiring diagram for 5-pin socket M12x1, type 763

Six-wire technology is not possible for M12 socket variant. In quarter bridge and half bridge mode, the internal half-bridge completion must be activated via the solder bridge on the circuit board (also possible in the factory as a free order option).

1. Half bridge completion must be activated at the same time.
2. The negative differential input 25, 7,16, 34) must be connected to the corresponding half-bridge completion (24, 6,15, 33).

Adjusting the sensitivity
The sensitivity of channels 1 to 4 can be adjusted. On the circuit board of the BSC4A, each channel has a jumper post field with 4 plug options in total .

Opening the device

1. All 4 screw covers and the fastening screws on each end cover should be removed.
2. The cover with the (37-pin Sub-D socket) must be loosened using the two hexagonal bolts.
3. The circuit board is unplugged from the side of the 15-pin Sub-D socket.
4. In the M12 socket version. the cover is pushed through the housing slightly slanted.

Note:
Amplifier channels have fixed gain settings and are not adjustable for specific load cell output signals. Because of this, the amplifier output will typically be less than the nominal 10V or 20mA at oad cell full scale.
