Stepping Relay Unit G9 B
Caution
Product Description
A stepping relay unit that allows the step status to be grasped at a glance with the LED display.
[Features]
·Contact relay output allows 2 A (250 V AC, 30 V DC) switching.
·Stepping control suitable for pump control and process control are made into a unit.
·There are 2 types of steps; 6 circuits and 12 circuits.
· Restores to step initial state due to reset input.
·With the retention function that stores the stepping status in the internal memory for 10 days even in the event of a power failure. (The output contact is off state during a power failure.)
·Equipped with a failure detection function that detects on state failures of the built-in relay drive element due to such as external noise. An alarm LED is displayed and an alarm is output at the contact. (Relay contact failure and chip welding failure cannot be detected)
· Terminal block designed with finger protection to prevent electric shocks.
·With LED display that allows the step status to be grasped at a glance.
[Applications]
·Used where sequential circuit switching is required.
