Weidmüller UR20-1SSI / Lenze W580-C-NT-003 — synchronous serial interface (SSI) module, single-channel, 24 V DC, PUSH IN, IP20, u-remote system, order no. 1508090000. A single-channel SSI functional module for the u-remote system, designed for high-precision positioning tasks using absolute value encoders. The module supports both listening and master mode operation, making it suitable for a wide range of encoder integration scenarios. SSI data is transmitted in Binary or Gray-Code format, with a maximum cable length of 320 m at 125 kHz and a delay time of 1 µs. Digital inputs feature reverse polarity protection and an integrated sensor supply sourced from the input current path (UIN). The module electronics supply the connected sensors from the input current path. Compatible with all u-remote fieldbus head stations.

Applications
- High-precision absolute position acquisition using SSI-compatible encoders — the module operates in master mode to actively clock data from the encoder, or in listening mode to passively monitor an existing SSI link between an encoder and another controller, covering both standalone and redundant monitoring topologies
- Long-distance encoder connections in machine and plant engineering — with a maximum cable length of 320 m at 125 kHz, the module is suited to large-format systems such as cranes, gantries, conveyor lines, and printing or packaging machines where the encoder is physically distant from the control cabinet
- Flexible data format support (Binary and Gray-Code) for integration of a broad range of commercially available SSI absolute encoders without additional signal conversion hardware
- Positioning and speed feedback in servo and motion control applications within the u-remote system, providing precise encoder data directly over the fieldbus to the controlling PLC or drive system
- Hazardous area installations (ATEX/IECEx) and marine applications requiring certified SSI functional modules with ABS, ClassNK, DNV, and KR approvals
