Reviews For IS200EXTBG2A

Internal Review

The IS200EXTBG2A model is the first of two simplex controls within the EXTB models. This model is used with other different models within the EX2100 series but tends to fail relatively easily due to the high number of easily pliable, and delicate fuses. - AX Control Technician
