The IRIS 500 amplifier is composed of

- Motherboard = M
- Analogboard = A

and if required

- Digitalboard = D

The amplifier is composed basically of motherboard and analogboard, but when discrimination is difficult, for example between adjacent and frontal flames, digital board is necessary because it will accurately define the flame-out ratio with respect to the burner and the adjacent or opposite burners. The flame signal can be an analog 0 - 20 mA on analogboard or/and a four digit LED display on digitalboard.
