The analog input circuit can be alternatively configured to
provide additional digital inputs (DIN7 & DIN8) as shown:
1
2
3
DIN7 DIN8
4
NOTES:
When an analogue input is configured as a digital
1.
input the threshold values are as follows:
1.75 V DC = Off
3.70 V DC = On
AIN1 can be used with:
2.
0 - 10 V, 0 - 20 mA and -10 V to +10 V
AIN2 can be used with:
0 - 10 V and 0 - 20 mA
Terminal 9 (24 V) can also be used to drive the
3.
analog inputs when used as digital inputs. Terminals
2 and 28 (0 V) must be linked together.
