Features of the board by RG4tech:
- 12V or 24V DC power supply (depends on components mounted)
- 8 opto-isolated inputs (12-24V voltage depends on mounted resistors)
- 8 relay outputs (with common every 4 relays, 1 relay configurable as NO/NC)
- 1 led output on board
- 1 input for on-board DS18B20 temperature sensor
- 2 freely configurable analog inputs (0-5V, 0-10V, 0-20mA) depending on resistors mounted
- analog inputs conditioned by LMV358
- overvoltage protection by transzorb and zener
- filter inductance on 5V supply
- filter inductance on analog circuit supply
