1 Actual turn-on and turn-off times equal the polling time plus the module time.
2 Polling time varies based on the SNAP I/O processor (brain or on-the-rack controller), processor configuration, and Ethernet
host communication activity.
3 The high-density digital module uses a 16-bit counter, but the processor used with the module accumulates counts to 32 bits
by periodically getting and clearing the module’s counts and adding to current values. Update time varies based on number of
modules and Ethernet communication demands.

16-point input modules: Each point is optically iso-
lated from other points on the module.
32-point input and output modules: The module is
divided into four groups of eight points. Groups are
isolated from each other, but points within a group
are not isolated from each other. Groups must be
externally fused.
None; use the handheld OptoTerminal-G20 for mod-
ule diagnostics and commissioning, or for 32-point
modules, connect to an optional breakout rack.
2–30 ms typical
16-point input modules: 15–20 ms
32-point input modules: 6 ms
Output modules: 100 microseconds
Counting occurs on the module.
Counting is available with SNAP-PAC-R1
PAC-EB1
Counting speeds:
On 32-point modules, 0–50 Hz @ 50% duty cycle
On 16-point modules, 0–25 Hz @ 50% duty cycle
(Speed depends on module; see specifications for
each part number.)
Firmware 8.1 and higher, yes.
Firmware 8.0 and lower, no.
Firmware 8.1 and higher, yes.

Input modules: Each point is optically isolated
from other points on the module.
Most output modules: Points are not isolated
from each other. Points share a common fuse. For
isolated modules, see the SNAP Digital Ouput
Modules Data Sheet (form #1144).

High-speed counting occurs on the I/O processor
(brain or on-the-rack controller) and can be config-
ured for any point. (High-speed counting is avail-
able on SNAP-PAC-R1
SNAP-PAC-SB1 processors.)
Counting speed varies based on the processor
and the speed of the module. Example: SNAP-
PAC-EB1 brain with SNAP-IDC5-FAST: up to 20
KHz
SNAP-IDC5-FAST: 25 microseconds
SNAP-IDC5: 5 ms turn-on, 15 ms turn-off
