INPUT SPECIFICATIONS
Input modules: Mini-M series; output 1 – 5 V DC;
(Each input must be isolated by signal conditioners. Non-isolated modules such as M2BW is not usable.)
Analog Input
Input range: See each I/O module spec.
Voltage at the field I/O terminals limited within 30 V DC for UL.
Isolation: transformer (by Mini-M module)
A/D conversion output: 16-bit binary
Signal range 0 – 100 % is converted into hexadecimal 0000 – 1770 (0 – 6000).  -15 to 0 % is represented by 2’s complements.
Overall range is represented by hexadecimal FC7C – 1AF4
(-900 – +6900), for -15 – +115 %.
Note: In the firmware version 3.00 or later, analog input range 0 – 100% can be converted into hexadecimal 0000 – 2710 (0 – 10000).
In addition, negative values of analog input range -15 to 0% can be converted into signed absolute values.
Refer to the instruction manual for details.

OUTPUT SPECIFICATIONS
Output modules: Model M2VS; input 1 – 5 V DC
Analog Output
Output range: See model M2VS spec.
Isolation: Transformer
D/A conversion output: 16-bit binary
Signal range 0 – 100 % is converted into hexadecimal 0000 – 1770 (0 – 6000).  -15 to 0 % is represented by 2’s complements.
Overall range is represented by hexadecimal FC7C – 1AF4 (-900 – +6900), for -15 – +115 %.
Note: In the firmware version 3.00 or later, analog output range 0 – 100% can be converted into hexadecimal 0000 – 2710 (0 – 10000).
