Table 1: Defines of interface
Digital IO interface: PIN 1 to 3 is a dry contact output interface with complementary
functions of normally open and normally close. PIN2 is the common port of the dry
contact. Dry contact output capacity: 1A/30VDC or 0.15A/220VAC; PIN 5 to 6 are dry
contact input interfaces, which can be set for external control of the output, external
fault feedback, or external control of the buzzer;
