OP2: BCD parallel data input interface [BCI]
Parallel interface for receiving setting data from external devices. Terminals and
internal circuit are electrically isolated by photo-couplers.
OP4: RS-485 communication interface [485]
RS-485 is capable of longer distance communication than RS-232C,
and multiple of F805AT-BC can be connected in parallel identifying them
with unique IDs.
OP8: Analog IN/OUT interface [ANA]
Analog IN/OUT interface with two analog input channels and three analog output
channels.
Analog input ×2 （separately functionable）
Analog output ×3 （separately functionable）
Pulse input ×1
* Use shielded twist-pair cable for connections.
