Increasing the Input Delay Time

You can increase the input delay time (DT) for channels 00 through 07. Select the
input delay time by setting the corresponding bits in the output image table
(complementary word) for the module.

For example, to increase the off-to-on delay time to 12ms for an ac input module at
address rack 1, module group 0, set bits 02, 01, and 00 as shown below.
