FAQ

Q: What is the difference between MB-C3-AI16-KS-131961 and MB-C3-AO16-KS-131957?
A: MB-C3-AI16 is analog input backplane; MB-C3-AO16 is analog output backplane for control output barriers.

Q: Which barrier fits this motherboard?
A: Mainly KFD2-STC4-Ex1 HART analog input isolated barrier.

Q: Is this board discontinued?
A: It is legacy KS-series backplane for Yokogawa CS3000, original production stopped, supplied as surplus, refurbished and tested spare parts only.

Q: Does it include KFD2 barrier modules?
A: No, this is only the backplane motherboard; KFD2 barrier modules are sold separately.
