This manual provides safety warnings and general information for the Delta DVP-ES/EX digital I/O extension units. It explains that the unit is an open‑type extension that must be installed in an enclosure away from dust, humidity, electric shock risk and vibration, and that AC mains must never be connected to the I/O terminals.\n\nThe guide details wiring diagrams, DIN‑rail mounting procedures, power‑supply requirements, input and output specifications, and system application examples. It also lists environmental limits, grounding rules, and protection measures for reliable operation.
