FAQ for CJ1W-ID211
What's the difference between ID201 and ID211?
ID201: 8 points, DC12-24V range. ID211: 16 points, DC24V only. ID211 provides double density at same width, more cost-effective for 24V systems.
How many ID211 units can I use in one CJ system?
Maximum 40 I/O units per CPU rack (excluding CPU and power supply). Limited by CPU's I/O capacity and power supply capacity. Check power budget before adding units.
Can I mix 24V and 12V inputs?
ID211 is 24V only. For 12V inputs, use ID201 (DC12-24V range). Each unit's common is isolated, so you can have different voltage levels per unit.
What's the power consumption?
Internal: 100mA at 5VDC (from backplane). External: 7mA per input at 24VDC (from sensor supply). For 16 inputs ON: 112mA external current.
