Model 2608 is an analog I/O module that connects to Ethernet through a 2601 communication module. It has sixteen differential analog inputs and 0, 4 or 8 analog outputs. It is a member of the 2600 series of smart I/O modules.
Common mode voltage range
The CMV range for analog inputs is -10 to +10V for both the 100mV and 10V input ranges.
Visual identification
- Is there a visible difference between models 2608-0, -4 and -8?
Yes. The 2608 circuit board has footprints for two DAC chips (marked "LTC2704") which are located near the analog output connectors. On earlier board revisions, these chips have reference designators U6 and U27; on newer revisions they are U9 and U29. The DAC chips are populated differently for each model. You can identify the model by the number of installed DAC chips:
| Model | DAC chips |
|---|---|
| 2608-0 | 0 |
| 2608-4 | 1 |
| 2608-8 | 2 |
