Voltage Output
4 outputs (4 words allocated)
1 to 5 VDC,0 to 10 VDC, or –10 to 10 VDC
2 kΩ min.
0.5 Ω max.
1/6000 (full scale)
0.4% full scale
0.8% full scale
16-bit binary (4-digit hexadecimal)
Full scale for –10 to 10 V: F448 to 0BB8 Hex
Full scale for other ranges: 0000 to 1770 Hex
2 ms/point (8 ms/all points)
Photocoupler isolation between analog I/O terminals and internal circuits. No isola-
tion between analog I/O signals.
5 VDC: 80 mA max.; 24 VDC: 124 mA max.
The analog values depend on the output signal ranges, as shown in the fol-
lowing diagrams.
When the output exceeds the specified range, the output signal will be fixed at
either the lower limit or upper limit.
A maximum of 7 Expansion Units or
Expansion I/O Units can be connected.
