SSI / Encoder / Quadrature Counter
Each module incorporates four (4) independent isolated programmable SSI/encoder/counter channels. These encoder/counter channels can interface directly to independent industrial encoders without any concern about groundings. Each channel is programmable as:
- SSI interface controller: The channel will output a clock to the encoder and will receive the encoder positional data signal. The SSI controller has a programmable clock rate.
- SSI “Listen Only” mode receiver: The channel will accept both the clock and positional data signal as inputs. The data word can be programmed in binary or gray codes with parity.
- Quadrature encoder counter: The channel can accept an index pulse in conjunction with the A and B signal inputs.
- Incremental encoder reader: Sub-programming options include pre-loadable up/down counters and 1x, 2x or 4x input format.
- General purpose counter: The channels are pre-loadable and can be controlled as an UP or DOWN counter which can be fed via a programmable internal clock source or an external signal trigger.
