The WFFP-1-3P signal isolation converter from Yifeng Sensor provides three synchronized isolated outputs for encoder pulse signals with selectable 5 V TTL…
The WFFP-1-3P is a pulse‑signal isolation and distribution module designed for industrial 4.0 control systems. It accepts encoder pulse inputs (A, B, Z and their inverted signals) and can output three synchronized isolated channels, allowing flexible voltage level conversion between 5 V TTL and 24 V HTL.
The device uses high‑speed optocoupler isolation, supports DIN‑rail mounting, and offers configurable input and output voltage levels via dip‑switches. Detailed wiring definitions, terminal assignments, and example applications are provided for integration with PLCs, motor control cards, and other monitoring equipment. This manual is written in Chinese.

It provides three synchronized isolated output channels.
The input can be set to either 5 V TTL (single‑ended) or 24 V HTL (single‑ended).
Use the red switches S5, S4 and S2 to select 5 V TTL or 24 V HTL for each of the three output channels.
The device supports a signal bandwidth up to 250 kHz.
