Stepping Relay Unit G9B CSM_G9B_DS_E_3_2 Ideal for Controlling Pumps and Production Lines with Six or Twelve Stepping Circuits • 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. Refer to Safety Precautions for All Relays. Ordering Information When your order, specify the rated voltage.

DIN track mounting hook Stepping signal input terminals Reset signal input terminals. Display Description POWER Lit Lit when power is supplied to the G9B and the G9B is ready to operate or in operation. Not lit Not lit when power is not supplied to the G9B. ALARM Lit Lit when there is a control contact error (i.e., when a built-in relay driving element is malfunctioning). Not lit Lit when the G9B is in normal operation. 3 G9B Operation ■ Timing Chart Normal Operation with No Reset Signal Power supply Step signal Reset signal 01 contact 02 contact A different contact is selected in numerical order per step signal pulse. When the contact currently selected is 06, 01 will be selected with the next step signal input. 03 contact 04 contact 05 contact 06 contact Normal Operation with Reset Signal Power supply Step signal Reset signal 01 contact The G9B switches an active control terminal over to another control terminal and makes it active whenever the G9B receives a single step input pulse. If a reset signal is input to a control terminal of the G9B when the G9B is in stepping operation, terminal 1 of the G9B will become active. 02 contact 03 contact 04 contact 05 contact 06 contact AL contact Emergency Case (ON Error) Power supply Step signal Reset signal 01 contact 02 contact If an internal contact of the G9B is incorrectly turned ON by the internal relay driving element that drives the internal contact due to external noise, the G9B will reset itself to its default status (i.e., contact 01 of the G9B will be turned ON) and turn its alarm contact ON so that the ALARM indicator of the G9B will become lit. When the G9B is turned OFF, the alarm contact will turn OFF and the ALARM indicator will not be lit. In this example, contact 05 is incorrectly turned ON. 03 contact 04 contact 05 contact 06 contact AL contact 4 G9B Emergency Case (ON Error) Power supply Step signal Reset signal 01 contact 02 contact If an internal contact of the G9B is incorrectly turned OFF by the internal relay driving element that drives the internal contact due to external noise, the G9B will reset itself to its default status (i.e., contact 01 of the G9B will be turned ON) when the internal contact incorrectly turned OFF becomes active. In this example, contact 05 is incorrectly turned OFF. 03 contact 04 contact 05 contact 06 contact AL contact Dimensions Note: All units are in millimeters unless otherwise indicated. G9B-06 91 max.

Safety Precautions Refer to Safety Precautions for All Relays. ■ Memory Backup Function The G9B has a built-in memory that stores the setting status for 10 days without power. All contacts are released when no power is supplied. When the G9B is turned ON again, the internal contacts will be set to the previous setting status. When power is not supplied, the output contacts will turn OFF. If a reset signal is input while power is not being supplied, the next step will be step 01 when power is restored. When 24 VDC is supplied to the G9B, make sure that the polarity of the power is correct. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters into inches, multiply by 0.03937.
