Key Features and Benefits

Universal Input Compatibility

The DSMB123 supports 4 universal analog input channels, accommodating a wide range of sensors including thermocouples (J, K, T, E), RTDs (Pt100, Pt1000), and standard process signals (4-20mA, 0-10V). This versatility eliminates the need for multiple specialized modules, simplifying inventory management and reducing installation complexity. It is particularly valuable in facilities with diverse sensor types, such as mixed temperature and pressure monitoring systems.

Advanced Signal Conditioning

Equipped with high-precision filters and amplification circuits, the DSMB123 minimizes the impact of electrical noise, drift, and interference on sensor signals. This ensures that outputs to control systems are accurate and stable, even in electrically noisy environments like manufacturing floors with heavy machinery. The module’s low temperature drift (±0.01% FS/°C) further enhances long-term measurement reliability, critical for applications requiring consistent process control.

Robust Isolation Protection

With 2.5kVrms isolation between inputs, outputs, and ground, the DSMB123 protects sensitive control equipment from voltage spikes, ground loops, and transient surges common in industrial settings. This isolation prevents signal degradation and equipment damage, extending the lifespan of connected PLCs and DCSs. It also enhances system safety by isolating field-side high-voltage risks from control-side electronics.

Compact and Easy to Integrate

The DSMB123 features a compact design (100mm x 75mm x 30mm) that saves space in control cabinets, making it ideal for installations with limited room. Its DIN-rail mounting capability allows for quick, tool-free installation, while pluggable terminal blocks simplify wiring and reduce setup time. The module’s plug-and-play compatibility with standard 24V DC power supplies ensures seamless integration into existing industrial infrastructures.

Flexible Output Configuration

Each of the 4 output channels can be independently configured as 4-20mA or 0-10V, enabling compatibility with a wide range of receiving devices. This flexibility allows the DSMB123 to adapt to varying system requirements, whether connecting to legacy PLCs with current inputs or modern DCSs using voltage signals. Output scaling and calibration can be easily adjusted via software or DIP switches, ensuring precise alignment with process ranges.
