Analog Output Units
Section 7-3
• CPM1A Expansion Unit errors are output to bits 0 to 6 of word A436. The
bits are allocated from A436.00 in order starting with the Unit nearest the
CPU Unit. Use these flags in the program when it is necessary to detect
errors.

Analog Output Units
Each CPM1A-DA041 Analog Output Unit provides four analog outputs.
• The analog output signal ranges are 1 to 5 V, 0 to 10 V, -10 to +10 V, 0 to
20 mA, and 4 to 20 mA. The resolution is 1/6,000. The open-circuit detec-
tion function is activated in the ranges of 1 to 5 V and 4 to 20 mA.
• The Analog Input Unit uses four output words, so a maximum of three
Units can be connected.
