    Input/Output Subsystem Overview The maxPAC Input/Output System links the maxDNA Distributed Control System to real world process control inputs and outputs. The Input/Output system uses a compact design to provide the system with greatly enhanced I/O capacity in relatively little space. A close relationship exists, in turn, between this I/O system and the maxDNA Distributed Processing Unit (DPU) which it serves.

    IOP383 Six-pack assembly to accommodate a DPU or a Model 564 I/O module in the right most position along with six maxPAC I/O modules; the DPU takes up the equivalent of two maxPAC I/O module positions. IOP381 Four-pack assembly to accommodate four maxPAC or Model 564 I/O modules.

    I/O. This Power Supply Assembly consists of a 19-inch rack mount or flush mount chassis accommodating up to six independent 10 amp power supply modules. Metso Automation MAX Controls typically installs the power supply modules in an N + 1 redundancy configuration. Because each module is individually isolated, the chassis can be split to provide both system power and loop power.
  • Page 14: Field Termination Options

    Input/Output Subsystem Field Termination Options A maxPAC system uses two field cable termination approaches: Local Terminations Field cables terminate directly on the I/O module. Remote Terminations Field cables terminate on terminal blocks remotely module with interconnecting cable back to the I/O module.

  • Page 16: Cabling, Power, And Ground Wiring

    The I/O system requires a 24 Vdc ±4.0 Vdc power supply. Normally, this is a maxDNA power supply mounted in the cabinet holding the DPU; to ensure reliability, Metso Automation MAX Controls recommends using a maxDNA power supply exclusively. If another 24 Vdc power supply is used, it must meet the same specification requirements as the maxDNA supply.

    (CPO307), a 15-foot cable (CPO315), or a special length cable. The maximum number of modules supported by the DPU4E within a cabinet or cabinet pairs is 60 maxPAC modules. This number of modules is reduced when the I/O bus is extended to other cabinets. A bus terminator (CPO402) must be installed at the end of the I/O bus connection.

  • Page 19: Module Addressing

    The lower switch is the low order address and the upper switch is the high order address. maxPAC modules use one, two or eight addresses. The address set on the module is its base address. For the eight-address module the base address is the address of channel 1.
