Product details
Isolate digital signals between 3.3 V or 5 V logic circuits. The module provides three forward channels, one reverse channel and an isolated output supply.
Product features
- 3.3 V and 5 V logic-level connections
- Three forward digital channels and one reverse channel
- One isolated output supply, selectable between 3.3 V and 5 V
- Voltage selection by latching push button
Connecting your interface
For conventional four-wire SPI, the forward channels can carry clock, MOSI and chip-select, with the reverse channel carrying MISO. A separate-TX/RX logic UART uses one channel in each direction. Match signal levels and interface timing to your circuit.
RS232, RS485 and CAN connections require appropriate transceivers between the logic signals and the bus wiring.
Use the supplied connection diagram for the three forward channels and one reverse channel. Press the voltage-select button for a 3.3 V isolated supply; release it for 5 V.
