FAQ
Q: Can this module be integrated with older CENTUM systems?
A: It is designed for CENTUM VP systems but may be compatible with certain legacy FIO systems; consult Yokogawa support.
Q: Does it support explosion-proof environments?
A: This model (P50/D5A00) does not have explosion protection. Use Yokogawa’s certified modules for hazardous locations.
Q: Are pushbutton inputs supported?
A: Yes, the “P” suffix indicates pushbutton input capability.
