1. GENERAL OVERVIEW

️· Product: WSB Series Isolated Differential Input Signal Conditioners/Isolators. These are versatile devices used to condition and isolate signals.
️· Function: They accept differential input signals, condition them (amplification, filtering, linearization, etc.), and output a scaled and isolated signal. Primarily intended for industrial automation, process control, and data acquisition.
️· Key Features:
- Isolation: Crucially, these devices offer electrical isolation between the input and output circuits and the power supply circuit. This protects connected systems from ground loops, noise, and voltage transients.
- Differential Input: Designed to process differential signals (two wires carrying opposite polarity signals). This dramatically reduces the effects of common-mode noise (noise that is present on both wires).
- Programmability (potentially): Some models allow for programming via serial communication (not detailed in this datasheet excerpt).
- Flexibility: Configurable scaling and offset adjustment.
- Accuracy: High accuracy and low drift.

2. INPUT/OUTPUT

️· Input:
- Type: Differential.
- Range: Variable. The specific input voltage range is model-dependent.
- Common-Mode Range: Not explicitly listed, but an important characteristic to check on a specific model datasheet. The wider the common-mode range, the more robust the device is to noise.
️· Output:
- Type: Scaled and Isolated.
- Range: Variable, configurable.
- Output Configuration: Supports various output configurations to match application requirements.
- Scaling and Offset: The output signal can be adjusted for gain and offset to match the requirements of the downstream system.

3. POWER

️· Supply Voltage: Variable. The specific supply voltage range is model-dependent. Requires a separate power supply.
️· Isolation: The power supply is also electrically isolated from the input and output circuitry.

4. PERFORMANCE

️· Accuracy: High accuracy and low drift. This means the output will remain accurate over time and temperature changes. The datasheet mentions “Low Drift Output”.
️· Linearity: Offers good linearity, meaning the output signal is directly proportional to the input signal.
️· Response Time: Not specifically listed, but a factor to consider for dynamic applications.
️· Temperature Range: Operating Temperature Range is typically -40°C to +85°C, but this is model dependent.
️· Common-Mode Rejection Ratio (CMRR): High. This is a key indicator of how well the device rejects common-mode noise.

5. PHYSICAL

️· Package Type: Likely surface-mount (SMT). The schematic shows a "Base Socket," suggesting a module design.
️· Dimensions: Not detailed.
️· Mounting: DIN Rail mounting possible.
️· Spacing: "no extra space is needed between units"
