FP01 REFERENCE MAIN BOARD / RELAYX8 REV 4.0
8-circuit relay
Reference board RELAYX8
RELAYX8 is an 8-circuit relay output reference board that carries SAIence's common control board FP01. On RS485 commands, FP01 switches the 8 latching relays (AC 250 V 5 A) on RELAYX8 ON/OFF per circuit or per group.

01 — HOW IT WORKS
SAIence sells FP01
The customer designs the main board
SAIence sells the common control board FP01 and the software that runs on it. RELAYX8 is a reference board verified in combination with FP01. After confirming operation with the evaluation test board, the customer builds the production main board to suit the application and enclosure.
RELAYX8 test board
- For verification and evaluation in combination with FP01
- Verify on real hardware from RS485 commands to 8-circuit relay operation
- Not sold as a production product
Main board
- Design and manufacture your own main board with RELAYX8 as a reference
- Change the relay type, number of circuits, power supply and connectors to suit the application
- Mount FP01 to complete a relay control module
NOTEThis page presents RELAYX8 as one example of a main board used with FP01. For FP01 itself, see the FP01 product page →.
02 — SYSTEM
Signal flow from FP01
FP01 handles communication, processing and relay control; the main board carries the power supply, RS485 driver, relays and drive circuits. Because the roles are divided, the function changes simply by redesigning the main board.
RS485
Receives 12-byte commands from the higher-level controller. The driver IC is mounted on RELAYX8.
RELAYX8UART→
Arduino UNO R4 compatible
The RA4M1 on FP01 interprets commands and manages the ON/OFF state of 8 local addresses and groups.
FP01I²C→
PSoC 4
On instruction from the RA4M1, outputs relay control signals for 8 circuits.
FP01CTRL→
Relay ×8
The drive circuits on RELAYX8 drive the Set / Reset coils of the dual-coil latching relays and switch each of the 8 load circuits ON/OFF.
RELAYX803 — 8CH RELAY
8 circuits with individual and group control
RELAYX8 has 8 local addresses. In addition to switching each relay ON/OFF, it can switch them together per group (ON / OFF / TOGGLE of the v command). Click the cards below to try it.
* Contact movement is for illustration. Each relay is a latching type with a 1a contact (AC 250 V 5 A) that switches between two terminals (RelayNa / RelayNb) on the terminal block.

Main boards for FP01
The FP01 firmware identifies the main board by its module type ID and switches the number of local addresses and the control method. RELAYX8 is type ID 4 (8 local addresses). For every type, the customer builds the main board; SAIence provides reference boards verified in combination with FP01 for evaluation.
