It is often the case that the shield lead needs to be grounded on programmable-controller side.
In these cases, be sure to connect the shield lead to terminal 9 of this module and then to the
cubicle's ground terminal.
When connecting a load to the comparison output, connect a 24 V ±4 V DC power supply
between the +V and C0/C1 terminals (C0 and C1 are intenally connected together).
2-phase input (up/down counting)
1-phase input (up counting)
Stop input (disabling pulse input when turned on, and enabling it
when turned off and latched)
