INPUT SPECIFICATIONS
■
Analog Input
Input range
: 1 – 5 V DC
Input resistance
: ≥ 1 MΩ
(Each input must be isolated by signal conditioners. Non-isolated modules such as M2BW and M8BW are not usable.)
■
A/D conversion output
•
Signed binary
(2-byte data)
Signal range 0 – 100 % is proportional to hexadecimal 0000 – 2710 (0 – 10000). -15 to 0 % is a negative range represented by 2's complements.
Overall range is represented by hexadecimal FA24 – 2CEC (-1500 – +11500), for -15 – +115 %.
•
Floating data
(4-byte data)
Initial signal range 0 – 100 % is proportional to 0 – 10000, that is possible to be scaled into a specific range.
OUTPUT SPECIFICATIONS
■
Analog Output
Output range
: 1 – 5 V DC
Load resistance
: 20 kΩ minimum
(Output must be isolated with signal conditioners.
When the transmission line is open, the last value sampled before failure is held. Non-isolated modules such as M2BW and M8BW are not usable. )
