Wiring diagram of D2 size instruments (48×48mm)
1: D2 size instruments don not support native 0

5V or 1
～
5V linear voltage input. The workaround
is done by voltage divider into 0
～
500mV or 100

500mV. External precise resistor 25ohm can be
parallel shunt to convert 4

then input from terminals 9 and 8.
2: For COMM/AUX slot,
installing S or S4 communication module provides
communication, installing L2 module provides AU1
alarm output,
installing L2 module provides AU1 alarm output,
installing L3 dual relay module (with parameter bAud=0) provides AU1 and AU2 alarm output,
installing L3 (with parameter bAud=2) provides AU1 and AL1 alarm output,
installing I2 module (with parameter bAud=1) provides MIO on-off input simulation SP1/SP2. The external switch should
be connected to terminal 3 and 5.
