PLC Connection Modules

A PLC connection module is a distribution module that multiplies the 24 V DC, 0 V or ground potential needed by sensors and actuators at an I/O station across many connection points. It is used to connect the supply and common terminals of three-wire sensors directly next to the I/O modules, without lining up separate terminal blocks. This category contains Delta Electronics AX-5 series models with 24 V DC for 16 I/O, 0 V for 16 I/O, a combination of 24 V DC for 8 I/O and 0 V for 8 I/O, and ground connection for 14 I/O. Select the module according to the potential to be distributed, the number of connection points required, and compatibility with the Delta AX-5 series I/O modules in your station. Verify from the manufacturer's data that the total current passing through the module does not exceed the permitted limit. A connection module only distributes potential; it is not a substitute for a digital I/O module that reads signals or drives outputs.

How to choose Connection Modules

A PLC connection module is a distribution module that multiplies the 24 V DC, 0 V or ground potential needed by sensors and actuators at an I/O station across many connection points. It is used to connect the supply and common terminals of three-wire sensors directly next to the I/O modules, without lining up separate terminal blocks.

  • Separate sensing, motion control, logic processing and operator interface requirements.
  • Select signal type, supply voltage, communication protocol and I/O count for the machine network.
  • Verify housing size, sensing distance and PNP/NPN output polarity against the PLC input card.
