ABB electronic timer CT-APS.22

Basic characteristics of the product

Function: Single function delay shutdown timer with 2 conversion contacts (2 c/o contacts).

Power supply voltage: Supports 24-48 V DC and 24-240 V AC.

Time Range: 10 time ranges are available, covering 0.05 s to 300 h. The time range can be pre selected by rotating the switch, and the front-end potentiometer has a direct reading scale for fine adjustment.

Status indication: 2 LED indicator lights, green LED (U/T) displays the control power supply voltage application and timing status (flashing during timing), yellow LED (R) displays the output relay power status.

Size: Width 22.5 mm, compact design.

Protection function: Optional sealable transparent cover (COV.01) to prevent unauthorized changes to time values; Integrated Tag Label (MAR.01).

Certification: Passed UL 508, CAN/CSA C22.2 No.14, GL, GOST, CB scheme, CCC and other certifications, with CE and C-Tick marks.

Working mode and function

Delay shutdown function: Continuous control of power supply voltage timing is required. When the control inputs A1-Y1/B1 are closed, the output relay is immediately powered on; When the input is disconnected, there is a delay and the green LED flashes; After the delay is over, the output relay will be powered off and the green LED will remain on. If the input closes again before the delay ends, the delay will reset and the output relay status will remain unchanged; When the control power supply is interrupted, the output relay will be powered off and reset with a delay.

Terminal description: The first conversion contact is 15-16/18, the second is 25-26/28, the control power is connected to A1-A2, and the control input is A1-Y1/B1.
