Relay output
1. PLC Output has two types: relay and
transistor. Please refer to chapter 2 for
electric specification related to it.
2. Operation indicator: When the output
is ON, the corresponding indicator will
be lit.
3. Insulation circuit:
For transistor output:
PLC internal circuit is photo-coupling
insulated.
For relay output:
PLC internal circuit is relay insulated.
4. Please pay attention to common
terminal’s wiring for output. Take
TP03-30MT-A as an example, Y0~Y1
share COM0, Y2~Y5 share COM1,
Y6~Y11 share COM2 and Y12~Y15
share COM3. See the following figure
for transistor output type.
