Material Composition
Constructed with precision analog components and conformal-coated PCBs in a rugged industrial enclosure.
Structural Characteristics
Standard 200 Series FBM dimensions (10.4 cm x 4.5 cm x 11.4 cm). Connects via a dedicated TA designed for low-level signal integrity.
Working Principle
Millivolt signals are amplified, isolated, and digitized using Σ-Δ technology. Data is transmitted to the controller over the Module Fieldbus.
Installation Requirements
Install on a 200 Series baseplate. Use shielded cables and maintain strict separation from high-voltage wiring to prevent noise coupling.
Usage Precautions
Ensure proper shielding and grounding for low-level signals. Verify input range configuration in the control software. No calibration required.
