The 0-57421- Pulsetach Input Module has within it a 16 bit internal timer, a 24 bit comparator, and a 24 bit counter. The digital inputs that are provided to be used in conjunction with the latch input, origin input, and count stop input have 5 to 12 VDC of electric potential. 

In many cases, the 0-57421- Pulsetach Input Module will be used to interrupt a variety of conditions, including the following: an external latch input, a marker pulse and origin input, a comparator equal condition, a periodic time interval, and an external count stop input.

When installing the 0-57421- module, be sure to follow the proper procedures.

Then, you will be able to insert the module into the desired slot within the rack. Be sure to use an applicable screwdriver to secure the 0-57421- to this slot. Lastly, you will want to mount a terminal strip near the module in such a way that the screw terminals are easily accessible to the operator.
