Features and Benefits
- ±10V and 4-20mA
- 4 independent channels
- For use with model 3AXX series 3-axis load cells
- Can be used with up to any 4 standard load cells (with mV/V output)
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 load cell full scale.

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).

The colors correspond to the core colors of the supplied 3-meter cable with 15-pin connector SubD15.
Automatic Zero Adjustment
Automatic Zero-adjustment is operated via push button or via digital input. Advice: the GNDio PIN 1 for digital input with PIN 8 is isolated from analog Ground PIN4. Analog grounds PIN4, PIN7, PIN13, PIN10 are connected.
Connect GNDio (PIN1) permanently with Ground (PIN4) and connect Supply Voltage (PIN9) via Relays or button with PIN8 for remote-controlled zero adjustment.

| Zero-Adjustment Input | PURPLE | 8 |
| Supply Voltage Output | GRAY | 9 |
The colors correspond to the core colors of the supplied 3-meter cable with 15-pin connector Sub-D15.

- Half bridge completion must be activated at the same time.
- The negative differential input (25, 7,16, 34) must be connected to the corresponding half bridge completion (24, 6,15, 33).
The automatic zero-point setting is done via push buttons or via the digital input. PIN 28 or 10 or 19 or 37.
Note: The GNDio PINs for the automatic zero adjustment are separated from the analog ground. Permanently connect GNDio (PIN1) to the ground of the supply voltage and connect the supply voltage, but at least 3.5V with PIN 28 or 10 or 19 or 37 for remote zero setting.

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.
