Define the Training Requirement
Select a PLC that exposes analog input directly or accepts an analog-to-digital expansion device. The evidence identifies both architectures: integrated analog I/O and a base PLC fitted with an AD board or module. Before purchase, confirm the required signal type and range because the available information does not specify voltage, current, temperature-sensor support, isolation, conversion time, or wiring method.
Compare the Identified PLC Options
| Manufacturer and model | Analog capability stated in the evidence | Selection constraint |
|---|---|---|
| Siemens S7-200 CPU224XP | 2 analog inputs and 1 analog output | Also identified with 14 digital inputs and 10 digital outputs; programming cable is an additional purchase. |
| Mitsubishi FX1S series | Analog input through an AD expansion board | The evidence specifically distinguishes the lower-cost expansion board from an expansion module. |
| Omron CP1H-XA40DT-D | 4 AD inputs and 2 DA outputs | Identified as the 24 V power version. |
| Omron CP1H-XA40DR-A | 4 AD inputs and 2 DA outputs | Identified as the 220 V power version. |
| Omron CP1L series | 1 AD input | Exact CPU model and analog specifications are not provided. |
| Delta DVP-SX | 2-channel, 12-bit analog input and 2-channel, 12-bit analog output | Signal ranges and exact variant are not provided. |
| HollySys LM3107E | No analog channel specification provided | Do not select it for this requirement until its analog capability is confirmed. |
Choose the Architecture
For experiments requiring both acquisition and generated analog signals, prioritize the CPU224XP, either listed CP1H variant, or the DVP-SX because the evidence explicitly identifies both analog inputs and outputs. For input-only exercises, the FX1S with an AD board or the CP1L may meet the stated objective, but the precise channel and electrical requirements remain unresolved.
Choose between the two CP1H variants by the available supply: CP1H-XA40DT-D is identified for 24 V power, while CP1H-XA40DR-A is identified for 220 V power. Do not infer output electrical type, analog range, or isolation from these model descriptions alone.
Verify Before Purchase
- Confirm that the complete order includes either integrated analog input or the required AD board or module; a base PLC without either does not satisfy the learning objective.
- Match the PLC power requirement to the laboratory supply, especially when choosing between the two CP1H variants.
- Obtain the exact datasheet for the selected model and verify analog signal range, channel count, resolution, wiring, conversion behavior, software compatibility, and required programming cable. The evidence confirms 12-bit resolution only for the DVP-SX.
FAQ
Which listed PLCs have built-in analog inputs and outputs?
The Siemens S7-200 CPU224XP is identified with 2 analog inputs and 1 analog output, the Omron CP1H variants with 4 AD inputs and 2 DA outputs, and the Delta DVP-SX with 2 analog inputs and 2 analog outputs.
Does a Mitsubishi FX1S provide analog input by itself?
The evidence specifies an FX1S combined with an AD expansion board. Confirm that the board is included and compatible with the selected CPU rather than assuming analog input is present in the base PLC.
What is the difference between CP1H-XA40DT-D and CP1H-XA40DR-A?
Both are identified with 4 AD inputs and 2 DA outputs. The stated distinction is the power supply: 24 V for CP1H-XA40DT-D and 220 V for CP1H-XA40DR-A.
