Different digital interface available
Balluff offers various digital interfaces such as:
- Pulse interface:
The time between a polling and the response pulse is directly proportional to the position
of the position transducer on the measurement path. The transmission of the impulses
with RS485 / 422 differential drivers guarantees interference-free transmission up to 500
m cable length.
- Synchronous serial interface SSI:
The position of the position transducer on the measuring path is transmitted serially to
the controller in a data word. Micropulse position transducers with SSI interface can be
connected directly to controllers or axis control cards with an SSI interface.
- Digital I/O interface:
The displacement sensors can be directly connected to the controller via digital inputs /
outputs and is therefore a cost-effective solution compared to analogue coupling.
Each output can be programmed with positive or negative logic and as a cam or as a
- Quadrature interface:
The encoder with quadrature interface is connected directly to a standard rotary encoder
interface (90 ° phase shift, A & B).
