TXM24C Hardware Manual
3.3.3 X3, X4, X5 Input
The X3, X4, X5 digital input is designed for low speed digital input operation between 5 and 24 volts. The
diagrams below show how to connect them to various commonly used devices like sensors, switches, re-
lays, PLCs, etc.
Note: If current is flowing into or out of an input, the logic state of that input is low or
closed. If no current is flowing, or the input is not connected, the logic state is high or
open.
3.3.4 What is COM?
“Common” is an electronics term for an electrical connection to a common voltage. Sometimes
“common” means the same thing as “ground”, but not always. In the case of the TXM24C drives, if
you are using sourcing (PNP) input signals, then you will want to connect COM to ground (power
supply -). If you are using sinking (NPN) signals, then COM must connect to power supply +.
Note: If current is flowing into or out of an input, the logic state of that input is low or
closed. If no current is flowing, or the input is not connected, the logic state is high or
open.
The diagrams on the following pages show how to connect the inputs to various commonly used
devices.
