Profibus-DP Absolute Encoder SAS/M58
The core components of the product are 100% localized, ensuring a stable and reliable supply chain as well as outstanding product quality.
It adopts high-precision magnetic sensing technology, providing both single-turn and multi-turn absolute encoder solutions.
Supports the Profibus-DP bus, enabling high-speed and stable data communication in industrial field applications.
Single-turn resolution is available up to 16 bits, while multi-turn resolution reaches 14 bits, meeting high-precision measurement requirements.
Features excellent shock and vibration resistance, with a protection rating of up to IP66, making it suitable for harsh industrial environments.
Built-in reverse polarity and short-circuit protection effectively reduces the impact of installation errors on the encoder.

| Signal | Description |
|---|---|
| ⊥ | Power supply ground (PE) |
| B (Left) | Data line B (pair 1), bus input |
| A (Left) | Data line A (pair 1), bus input |
| (-) | 0 V |
| (+) | 10 V … 30 V |
| B (Right) | Data line B (pair 2), bus output |
| A (Right) | Data line A (pair 2), bus output |
| (-) | 0 V |
| (+) | 10 V … 30 V |
| Note | The power supply needs to be connected only once (to either terminal set); when the termination resistor is enabled, BUS OUT is disconnected. |
| Red LED | Green LED | Status information / Possible causes |
|---|---|---|
| Off | Off | No power supply |
| On | On | The rotary encoder is ready for operation, but has not yet received any voltage-based configuration data; possible causes include, for example, incorrect address setting or incorrect bus connection. |
| On | Blinking | Parameter assignment or configuration error. The length of the received configuration or parameter assignment data is not plausible or the data is inconsistent; possible causes include, for example, an excessively high total resolution setting. |
| Blinking | On | The rotary encoder is ready for operation, but is not being accessed by the master (e.g. this condition may occur due to an incorrect address). |
| On | Off | The rotary encoder has not received any data within a certain period (approx. 40 seconds); the data line may be interrupted. |
| Off | On | Data exchange is operating in normal mode |
| Off | Blinking | Data exchange is operating in commissioning mode |
