These four inputs are shared by interrupt inputs, interrupt inputs in countermode, and quick-response inputs, but each input can be used for only onepurpose.7SectionBasic System Configurations1-22. This input is shared by the high-speed counter and synchronized pulse control functions.3. This output is shared by the pulse output and synchronized pulse controlfunctions. These functions can be used with transistor outputs only.1-2Basic System Configurations1-2-1 Stand-alone CPU UnitCPU Unit with 20/30 I/O PointsCPU Unit with 40 I/O PointsNumber of I/O points20 I/O points(12 inputs and 8 outputs)Power supply100 to 240 VAC24 VDC30 I/O points(18 inputs and 12 outputs)100 to 240 VAC24 VDC40 I/O points(24 inputs and 16 outputs)100 to 240 VAC24 VDC60 I/O points(36 inputs and 24 outputs)100 to 240 VAC24 VDCCPU Unit with 60 I/O PointsInputs24 VDC24 VDC24 VDC24 VDC24 VDC24 VDC24 VDC24 VDC24 VDC24 VDC24 VDC24 VDC24 VDC24 VDC24 VDC24 VDCOutputsRelayRelaySinking TransistorSourcing TransistorRelayRelaySinking TransistorSourcing TransistorRelayRelaySinking TransistorSourcing TransistorRelayRelaySinking TransistorSourcing TransistorModelCPM2A-20CDR-ACPM2A-20CDR-DCPM2A-20CDT-DCPM2A-20CDT1-DCPM2A-30CDR-ACPM2A-30CDR-DCPM2A-30CDT-DCPM2A-30CDT1-DCPM2A-40CDR-ACPM2A-40CDR-DCPM2A-40CDT-DCPM2A-40CDT1-DCPM2A-60CDR-ACPM2A-60CDR-DCPM2A-60CDT-DCPM2A-60CDT1-D1-2-2 CPU Unit, Expansion Units, and Expansion I/O UnitsUp to 3 Expansion Units or Expansion I/O Units can be connected to the expansion connector with expansion I/O connecting cables.
(Only one Expansion Unitor Expansion I/O Unit can be connected if an NT-AL001 Adapter is connected tothe RS-232C port because the CPU Unit’s 5-VDC power supply is limited.)There are four types of Units available: Expansion I/O Units, an Analog I/O Unit,Temperature Sensor Units, and a CompoBus/S I/O Link Unit.Expansion connectorExpansion I/O Unit or Expansion Unit(Analog I/O Unit, Temperature SensorUnit, or CompoBus/S I/O Link Unit)Expansion I/O connecting cable8SectionBasic System Configurations1-2A PC with 120 I/O points (the maximum) can be assembled by connecting threeExpansion I/O Units to a CPU Unit with 60 I/O points.CPM2A-60CDR-A× 1 Unit(36 inputs, 24 outputs)+CPM1A-20EDR1× 3 Units = 72 inputs, 48 outputs(12 inputs, 8 outputs)A PC with 6 analog inputs and 3 analog outputs (the maximum) can be assembled by connecting three Analog I/O Units.
(Only one Analog I/O Unit can beconnected if an NT-AL001 Adapter is connected to the CPU Unit’s RS-232Cport.)A PC with up to 6 temperature inputs for input from thermocouples or platinumresistance thermometers can be assembled by connecting Temperature SensorUnits.CompoBus/S I/O Link Units (Slave Units) can be connected to a CPU Unit.
I/Odata (8 inputs and 8 outputs) is transferred between the CPU Unit and the areaallocated to the CompoBus/S Slave. (The I/O data exchanged with the Slave isinternal data; there are no external input or output terminals.)Note1. Different types of Expansion I/O Units or Expansion Units can be connectedat the same time. For example, an Expansion I/O Unit, an Analog I/O Unit,and a CompoBus/S I/O Link Unit can be connected to the CPU Unit.2. When an NT-AL001 Adapter is connected to the RS-232C port, only one Expansion Unit or Expansion I/O Unit can be connected to the CPU Unit because of power supply limitations.Expansion I/O Units20-point I/O UnitUnitExpansionI/O Units20 I/Opoints12 inputs8 outputs8-point Input UnitMax.
