4. Using Pulse Catch Modules
1) Number of Modules
a) The following I/O references are necessary in the CPU Module for each Pulse Catch
and Counter Module.
• 16 consecutive input relays (Not needed if the pulse catch function is not used.)
• 17 consecutive input registers (Not needed if the counter function is not used.)
• 2 consecutive output registers (One set if count clear is not used.)
b) Therefore, the number of Pulse Catch and Counter Modules that can be used is deter-
mined by how many of the above I/O references are available in the CPU Module.
2) Installation Locations
a) A Pulse Catch Module can be mounted to any slot of the Mounting Base of any Rack.
It will occupy on slot.
b) The following diagram shows where to mount a Pulse Catch Module.
