Operation Description
Timing (µs)
Minimum Typical Maximum
Throughput The delay between the time the module receives a pulse and when
its real outputs and the SLC backplane are updated (based on a
count range). 300 700 1600
Input File Update
Time The delay between the time the module receives a pulse and when
the backplane count value is updated, including setting the I/O
interrupt. 300 600 1500
Output Turn-on
Time The time it takes for the real output to reach 90% output voltage
after commanded by the module, not including SLC scan time. – – 10
Output Turn-off
Time The time it takes for the real output to reach 10% output voltage
after commanded by the module, not including SLC scan time. – – 100
Inductive Turn-off
Time The time between the module receiving an input pulse and breaking
contact in a BULLETIN 110 contactor. – – 50
Rate Accuracy The accuracy of the reported rate as compared to actual input rate in
the equation: reported rate/actual input rate. – 0.005% 0.015%
