**in2_lcrit_alarm**



**in3_input**



**in3_label**



**in3_crit**



**in3_crit_alarm**



**in3_lcrit**



**in3_lcrit_alarm**



The driver provides the following attributes for input current:



**curr1_input**



**curr1_label**



**curr1_max**



**curr1_max_alarm**



The driver provides the following attributes for output current:
