A5: Up to 12.
Q6: What are its dimensions and weight?
A6: Measures 59 × 185 × 127.5 mm and weighs about 0.7 kg.
Q7: What power does the module consume?
A7: Roughly 150 mA at 24 V DC (~3.6 W).
Q8: What environments can it handle?
A8: Rated for +5 °C to +55 °C operation, storage down to –40 °C, protected to IP20, and designed against corrosion (ISA G3).
Q9: What certifications does it hold?
A9: It holds CE, RoHS, WEEE, and marine certifications like BV, DNV-GL, LR.
Q10: What’s included in the module package?
A10: It includes the CI855 interface module and the TP853 baseplate.
