G9B

• Built-in relays switch 2 A at 250 VAC or 30 VDC.

• Initialization of stepping with reset input.

• Uses memory that stores setting status for 10 days without power. All internal contacts are released when no power is supplied.

• Detects an internal element malfunction caused by external noise, indicates the malfunction with an alarm indicator, and turns the relay alarm output ON. (An internal relay malfunction or internal relay contact weld cannot be detected.)

• With safety-design terminals which prevent electric shock accidents.

• With easy-to-see indicators which display the stepping status.
