Analog Output Modules Selection Guide: Technical Criteria & Application Standards
Analog Output Modules selection guide: technical parameters, mounting and compliance standards, and Delta Electronics, Schneider Electric, GMT comparison.
An analog output module is an expansion module that converts a numerical value calculated in the PLC program into a continuous voltage or current signal such as ±10 V or 0-20 mA. It is used where stepless adjustment is needed, such as giving a speed reference to a frequency inverter, positioning a proportional valve, or sending a measured value to an indicator. This category includes Delta Electronics, ABB and GMT models with 2, 4, 6 and 8 channels, voltage (V), current (I) or both output types, and 12 and 16 bit resolution, as well as right-expansion and left-expansion types. Select the analog output module according to the signal type and range expected by the device to be driven, the channel count, the resolution, the conversion time and compatibility with your PLC series. On a current output, the maximum load resistance that can be connected is limited, while on a voltage output the minimum load resistance is limited; verify the values from the module datasheet. An analog output is not a power output; it only produces a reference signal and does not directly supply a motor, heater or valve coil. The Analog Output Modules category on Welibaba includes 17 active models from leading manufacturers such as Delta Electronics, Schneider Electric, GMT.
Key Technical Parameters for Selecting Analog Output Modules
To specify the right Analog Output Modules model for your panel or installation, verify the following parameters against your engineering schedule:
| Parameter | Typical Catalog Values | Verification Note |
|---|---|---|
| I/O Output | 2 Analog Çıkış-V I Tip, 2 kanal, 4 Analog Çıkış- V Tip, 4 Analog Çıkış-I Tip | Verify against project schedule and load calculation |
| Connection Type / Module | Dahili Standart, Sağa Genişleme, Sola Genişleme | Verify against project schedule and load calculation |
| I/O Input | Yok | Verify against project schedule and load calculation |
| Number of Analog Outputs | 2, 4, 8 | Verify against project schedule and load calculation |
Installation, Compatibility, and Commissioning Checklist
- Electrical & Mechanical Matching: Confirm that rated voltage, current capacity, and mounting dimensions align with the upstream and downstream components in PLC Input and Output Modules.
- Environmental & Enclosure Rating: Check IP protection class, housing material, and terminal capacity for dusty, humid, or high-vibration industrial environments.
- Related Product Groups: If your application calls for a different form factor or rating, compare sibling categories such as Analog Input Modules, Analog I/O Modules, Connection Modules.
