Input Specifications and Functions
| Item | Voltage input | Current input | |
| Number of analog inputs | 4 | ||
| Input signal range *1 | 1 to 5 V 0 to 5 V 0 to 10 V - 10 to 10 V | 4 to 20 mA *2 | |
| Maximum rated input (for 1 point) *3 | ± 15 V | ± 30 mA | |
| External input impedance | 1 M Ω min. | 250 Ω (rated value) | |
| Resolution | 4,000/8,000 (full scale) *6 | ||
| Converted output data | 16-bit binary data | ||
| Accuracy *4 | 25 ° C | ± 0.2% of F.S. | |
| 0 ° C to 55 ° C | ± 0.4% of F.S. | ||
| A/D conversion time *5 | 1.0 ms/500 μ s max. per point | ||
| Mean value processing | Stores the last "n" data conversions in the buffer, and stores the mean value of the conversion values. Buffer number: n = 2, 4, 8, 16, 32, 64 | ||
| Peak value holding | Stores the maximum conversion value while the Peak Value Hold Bit is ON. | ||
| Scaling | Enabled only for conversion time of 1 ms and resolution of 4,000. Setting any values within a range of ± 32,000 as the upper and lower limits allows the A/D conversion result to be output with these values as full scale. | ||
| Input disconnection detection | Detects the disconnection and turns ON the Disconnection Detection Flag. | ||
*1.Input and output signal ranges can be set for each input and output.
*2.Voltage input or current input are chosen by using the voltage/current switch at the back of the terminal block.
*3.The Analog I/O Unit must be operated according to the input specifications provided here. Operating the Unit outside these specifications will cause the Unit to malfunction.
*4.The accuracy is given for full scale. For example, an accuracy of ±0.2% means a maximum error of ±8 (BCD) at a resolution of 4,000.
*5.A/D conversion time is the time it takes for an analog signal to be stored in memory as converted data after it has been input. It takes at least one cycle before the converted data is read by the CPU Unit.
*6.By means of the D(m+18) setting, the resolution can be changed to 8,000, and the conversion time can be changed to 500 μs.
Output Specifications
| Item | Voltage output | Current output | |
| Number of analog outputs | 2 | ||
| Output signal range *1 | 1 to 5 V 0 to 5 V 0 to 10 V - 10 to 10 V | 4 to 20 mA | |
| External output impedance | 0.5 Ω max. | --- | |
| Maximum external output current (for 1 point) | 2.4 mA | --- | |
| Maximum allowed load resistance | --- | 600 Ω | |
| Resolution | 4,000/8,000 (full scale) *5 | ||
| Set data | 16-bit binary data | ||
| Accuracy *2 | 25 ° C | ± 0.3% of F.S. | ± 0.3% of F.S. |
| 0 ° C to 55 ° C | ± 0.5% of F.S. | ± 0.6% of F.S. | |
| D/A conversion time *3 | 1.0 ms/500 μ s max. per point | ||
| Output hold function | Outputs the specified output status (CLR, HOLD, or MAX) under any of the following circumstances. When the Conversion Enable Bit is OFF. *4 In adjustment mode, when a value other than the output number is output during adjustment. When output setting value error occurs or PLC operation stops. When the CPU Unit is on standby. When the Load is OFF. | ||
| Scaling | Enabled only for conversion time or 1 ms and resolution of 4,000. Setting any values within a range of ± 32,000 as the upper and lower limits allows D/A conversion to be executed and analog signals to be output with these values as full scale. | ||
| Ratio conversion function *5 | Stores the results of positive and negative gradient analog inputs calculated for ratio and bias as analog output values. Positive gradient: Analog output = A × Analog input + B (A: 0 to 99.99, B: 8,000 to 7FFF hex) Negative gradient: Analog output = F - A × Analog input + B (A: 0 to 99.99, B: 8,000 to 7FFF hex, F: Output range maximum value) | ||
*1.Input and output signal ranges can be set for each input and output.
*2.The accuracy is given for full scale. For example, an accuracy of ±0.2% means a maximum error of ±8 (BCD) at a resolution of 4,000.
*3.D/A conversion time is the time required for converting and outputting the PLC data. It takes at least one cycle for the data stored in the PLC to be read by the Analog I/O Unit.
*4.When the operation mode for the CPU Unit is changed from RUN mode or MONITOR mode to PROGRAM mode, or when the power is turned ON, the Output Conversion Enable Bit will turn OFF. The output status specified according to the output hold function will be output.
*5.By means of the D(m+18) setting, the resolution can be changed to 8,000, and the conversion time can be changed to 500 μs.
Caution: In the interenst of product improvement, specifications are subject to change without notice.
