1 “Mixed” means the rack can hold analog, digital, and serial modules. Most Ethernet-based I/O processors handle all
these types of modules; other processors do not. See the processor’s data sheet for details.
 
2 Power requirements shown are for a rack, a processor, and a full load of 2-channel analog modules (for the SNAP-
D64RS, a full load of 4-channel digital modules). Power requirements for other SNAP modules are higher. See module data
sheets.
 
3 “I/O Processor” means a SNAP brain or on-the-rack controller.
 
4 Digital features and module positions depend on processor. SNAP-PAC-R1 supports full digital features (high-speed
counting, quadrature counting, TPO, pulsing), but on larger racks, 4-channel SNAP digital modules must be in positions
0–7 only (32-channel digital modules can be in any position). SNAP-PAC-R2, SNAP-UP1-M64, and SNAP-ENET-S64 offer
more limited digital features but can use digital modules in any position. See the processor’s data sheet for details.
 
5 Four-channel SNAP digital modules can be used in positions 0–7 only.
 
6 Manufacturer’s part number (not available through Opto 22).
