CPU Base I/O (AI/AO1&2, DI/DO/PI 1&2) Wiring
A When wiring a 1-5 V Analog Input (AI), use configuration at left
B When wiring a 4-20 mA Analog Input (AI), use configuration at left
1 Field Device
2 Power Supply 30Vdc Max
3 Open Drain Type or Open Collector Device (Externally Powered)
4 500 mA load max
5 To AGND
6 To AIAOx
7 Dry contact
You should terminate all shields at chassis ground.
When using a digital output to drive an inductive load (such as a relay coil), place a
suppression diode across the load. This protects the DO from the reverse Electro-Motive
Force (EMF) spike generated when the inductive load is switched off.
