Frequently Asked Questions

How does the refurbishment process ensure reliability comparable to new modules?
Our factory-certified refurbishment includes complete disassembly, component-level inspection, replacement of wear-prone parts, calibration to original specifications, and multi-point functional testing under simulated load conditions. Each module must pass the same quality gates as new production units before receiving certification for resale.

Can the DAI 02 interface with third-party sensors and transmitters?
Yes, the module accepts standard industrial analog signals (0-10V, 4-20mA) from any manufacturer's sensors and transmitters. Signal compatibility depends on the transmitter output matching the module's input specifications, not on brand or protocol.

What are the typical applications where analog input modules provide the most value?
Analog input modules excel in continuous process monitoring applications including temperature control loops, pressure regulation systems, flow measurement circuits, and level monitoring installations where real-time variable tracking is essential for process optimization and safety.

Is special training required for installation and configuration?
Basic installation requires standard electrical and control panel skills including DIN rail mounting and terminal wiring. Configuration through the Freelance 2000 engineering software requires familiarity with the system programming environment.
