Hydraulic Control board

This board controls a 3 axes giant hydraulic engine. All the three axes are controlled simultaneously. The board senses 6 LVDT sensors from the engine pistons and executes 6 PWM ports to control 3 hydraulic differential solenoids – two PWM ports per channel.

1. CPU – STM32 from ST, ARM Cortex-3. 70Mhz
2. Internal Flash – 128KB
3. Internal RAM – 20KB
4. ADC – 8 ports x 12bit
5. PWM – 6 ports
6. IO – 8 channels. Optocouplers isolation.
7. Dual CAN bus – One for backup to the main channel – Sophisticated algorithm was developed to maintain this task in real time.
8. RS232 comm.
9. Built-In-Test
10. Inlet voltage – 10–36 V
11. Dimensions – 18×12 cm
