1. Sink/Source Inputs. All DC inputs in Nano can be used for either sink or source. We have used them only for sink. See the next note on Sink inputs for a schematic and more details.

2. Sink Inputs. Each input is basically a resistor with one end of each resistor tied to individual terminals. The other ends are tied together to a terminal labeled IN COM. This pull down resistance sinks voltage and current to common VDC. Sink Inputs. Each input is basically a resistor with one end of each resistor tied to individual terminals.

The output on the MSP is designed to be used as either sink or source. The MSP contains a sinking gate and pull-up resistor. Sink inputs can be wired directly to the MSP.

Make sure that the PLC input module and MSP input get their 24 VDC from the same source. Following is a schematic of a typical input. "%I0.?" may be any valid input. In the single channel drivers for the Nano the input is %I0.0 but may be changed if desired. In the multiplexed drivers for the Nano Channel 1 and 2 are %I0.0 and %I0.1 respectively but may be changed if desired.



3. Source Inputs. Each input is basically a resistor with one end of each resistor tied to individual terminals. The other ends are tied together to a terminal labeled IN COM. This pull up resistance sources voltage and current from +VDC. Source Inputs. Each input is basically a resistor with one end of each resistor tied to individual terminals.

The output on the MSP is designed to be used as either sink or source. The MSP contains a sinking gate and pull-up resistor. Source inputs can be wired directly to the MSP.

Using the input as source would increase the level of the signal and make it more immune to noise but it would double the current required when the signal is pulled to zero volts.

Make sure that the PLC input module and MSP input get their 24 VDC from the same source. Following is a schematic of a typical input. "%I0.?" may be any valid input.

Note: The true/false sense for a sourcing input is opposite that of a sinking input. In ladder logic the hardware input into the driver must be negated to provide the proper logic sense.

4. Relay Outputs. Relay outputs can be used as either sink or source. We recommend using them only for source since it eliminates the need of a pull up resistor. See the next note on Sourcing outputs for a schematic and more details. If using mechanical relay outputs you will have to slow the output driver down in order to debug it and not destroy the relay. We suggest using a scan time of 50 msec for the MSP analog output modules. Relay Outputs. Relay outputs can be used as either sink or source.

5. Output on Demand. In order to conserve the life of the relay output we suggest you add some extra logic that allows control of when the output is transmitted. If required please review the Omron or GE drives for the method. Output on Demand.

6. Input/Output Scan Time Ratio. For those drivers using both inputs and relay outputs we suggest using logic that runs the output a factor of 5 times or more slower than the input. This allows the input to run at a scan time of 10 msec and the output to run a scan time of 50 msec. This is necessary only when relay outputs must be used.

7. Source Outputs. Each output is basically a transistor or gate with one end of each transistor tied to individual terminals. The other ends are tied together to a terminal labeled OUT COM. This pull up contact sources voltage and current from +VDC. Terminal -V is used only for internal logic circuits on the field side of the isolator. Source Outputs.
