DPT-EG-MAN-DBR31-TECMAN-001-A3 Technical Manual
1. LoRa interface: LoRa embedded Antenna and footprint for external antenna connector (UMC)
Through the LoRa antenna interface, the user can communicate LoRa devices. The board includes an optional
connector for install an external antenna.
The current and certified antenna is omnidirectional and lineally polarized.
2. NFC interface
The board includes a 64-Kbit EEPROM for the NFC memory allowing faster data transfer between the NFC (I
2
C
communication) and the RF interface (NFC tag writer is recommended).
Write time:
- From I
2
C: typical 5ms for 1 byte
- From RF: typical 5ms for 1 block
3. Multipurpose connector footprint (GPIO): The multipurpose connector is integrated as a discrete component
and connected to the isolated interface, 24VDC.
For this footprint use FRVKOOP (in the image) or equivalent switch.
4. External multipurpose connector (B3): Designed to connect external devices powered at 24V, this
multipurpose connector without a specific footprint exposes a galvanically isolated connection to one of the
switches of the contact.
Signals:
o STO A
o STO B
5. Power and motor drive connector: Power supply input and SSR outputs. Connector SPT 2.5/4-V-5.0.
The board must be 24VDC powered. Located in the same connector are the outputs for motor driver (M1 and
M2), 24VDC, up to 15A.
Signals:
o 24V
o GND
o M1
o M2
