USA: +1 330 486 0001 Singapore: +65 6779 9091 Optical data coupler DAD15-8P Release date: 2019-09-18 15:52 Date of issue: 2019-09-18 120838_eng.xml The DAD 15-8P can be used to transfer data words eight bits wide bidirectionally. A device pair is required to set up a transmission route. One device is operated as the MASTER (high level on the Master/Slave input) and the second one as the SLAVE (low level on the Master/Slave input). All binary control signals present in parallel on inputs D1 - D8 are converted serially into an 8-bit sequence in the device, a re transferred over the light route and are again applied in parallel in the receiver to outputs D1 - D8. Interference-resistant PPM modulation is used to transfer binary signals. The entire cycle during which the two current 8-bit words are transferred one after the other in both directions, in the time multiplex procedure, lasts 35 ms. This corresponds to a data rate of 350 Baud. This time multiplex procedure is of no significance to the user, since the last data to be received is stored and is available on the outputs until the next change is made. Output behaviour when the beam of light is interrupted The behaviour of the data outputs when the light beam is broken can be adjusted with the aid of the 4 switch (data latch): OFF: Data outputs are turned off when the light beam is broken. ON: The last data to be received remains intact on the outputs when the light beam is broken. Input/output / emitter deactivation A high level on the ENABLE input is required to operate the DAD15-8P. If there is a low level on the ENABLE input, the emitter will be turned off. The ENABLE input has no function in SLAVE mode. Inputs and outputs, reception indicator: The states of data inputs and outputs are displayed individu- ally via LEDs. A high level on the input is indicated by a green LED. A red LED indicates an active output. Correct reception is indicated with the output and the RE- CEPTION INDICATOR LED. The SYNC output indicates the end of a transmit or receive cycle. Output data are valid with a falling edge and new input data can be read. x DAD15 100 Distance X [m] Stability control Relative received light strength 01 23 45 Function Sensitivity adjuster (behind the cover screw) Receiver Emitter RxD Power-on

Up to four MASTERS can be chained together in this manner. The devices must then be addressed by means of the A1 and A2 address switches. The SLAVE be- longing to the MASTER in question requires the same address switch setting. Arrangement and mounting The DAD15 data light barrier consists of an electronics unit with spring-loaded terminals and 2 M16 cable glands. The electronics unit is connected with an internal connector. It is also fastened to it with 4 screws. Accessories: OMH-DAD10 mounting angle Sync. Slave 1 (for reception only) Sync.
