With SSI- or Parallel-Input
Motrona signal converters with SSI- or parallel-input are designed to bridge the gap between absolute encoders, sensors, and control systems that require a different signal format. Whether you need to convert SSI (Synchronous Serial Interface) data into parallel outputs (Binary, Gray code, or BCD), or integrate legacy parallel signals into modern control architectures, these converters help ensure reliable communication and simplified commissioning.
At Encoder Technology, we supply industrial-grade Motrona converter solutions built for demanding automation environments. With same-day UK dispatch, global shipping, minimal lead times, and over 50 years of experience, we make it easy to source the right signal converter—backed by expert technical support.

What Are SSI- or Parallel-Input Signal Converters?
An SSI/parallel-input signal converter is a dedicated interface module that:
- Reads SSI signals from an absolute encoder (often up to 32-bit word lengths, model dependent)
- Converts the incoming data into a parallel output format such as Binary, Gray code, or BCD (model dependent)
- Helps older controls or PLC input cards use absolute position data without changing the encoder type
- Simplifies system integration when an application requires a specific electrical interface or output coding
Many applications use these converters to keep an existing PLC I/O concept while upgrading sensors, retrofitting machines, or standardising encoder types across sites.
Where Are SSI & Parallel Signal Converters Used?
These converters are used wherever encoder signals must be adapted reliably between sensors and control systems:
- Machine retrofits and upgrades – Retain existing PLC input cards while adding or replacing absolute encoders
- Packaging and production machinery – Ensure stable, readable position data for indexing, cutting, and feed control
- Material handling systems – Convert absolute position feedback for conveyors, diverters, and lift systems
- Automation and special-purpose machinery – Standardise signal formats across different encoder brands and machine platforms
- Test rigs and calibration benches – Provide convenient output formats for measurement and validation equipment
- Legacy control systems – Keep parallel-coded infrastructure operational without major rewiring or reprogramming
Benefits of Motrona SSI / Parallel-Input Converters
Motrona converters help reduce integration risk and speed up commissioning by providing a robust signal “translation layer” between devices.
- Reliable SSI decoding for absolute encoders – Stable conversion of serial absolute position data into usable outputs
- Flexible output coding – Support for common parallel codes such as Binary, Gray code, and BCD (model dependent)
- Reduced redesign work – Avoid changing PLC hardware or rewriting major sections of control logic when signal formats don’t match
- Cleaner troubleshooting – Easier to validate encoder values when signals are presented in a format your control system expects
- Industrial-grade build quality – Designed for switch cabinet installation and continuous operation in automation environments
- Supports modernisation without disruption – Ideal for phased upgrades where some parts of the system remain legacy

Get the Right SSI or Parallel-Input Converter for Your Application
Choosing the correct converter depends on factors such as encoder interface (SSI wiring and word length), required output coding (Binary/Gray/BCD), electrical output type, and how the PLC or downstream device reads the data.

Frequently Asked Questions
What does an SSI signal converter do?
An SSI signal converter reads serial absolute position data from an SSI encoder and converts it into another usable format—commonly a parallel output (model dependent).
Why would I need an SSI-to-parallel converter?
You may need one if your PLC or legacy control system expects parallel-coded inputs (Binary/Gray/BCD), but your encoder outputs SSI.
Can these converters work with Gray code or BCD?
Many models support multiple coding formats such as Binary, Gray code, and BCD—always confirm the required code format against the converter specification.
Are these converters suitable for control cabinets?
Yes. SSI/parallel converters are typically designed for DIN-rail or cabinet installation (model dependent), making them suitable for industrial panels.
