ORB24A21D工業(yè)自動化與控制的延時繼電器規(guī)格書PDF中文資料

Description

The ORB Series’ open PCB construction offers the user good

economy without sacrificing performance and reliability. The

output relay is available in isolated, 10A, DPDT or SPDT forms.

The time delay may be ordered as factory fixed, onboard knob,

or external adjustment. All connections are 0.25 in. (6.35 mm)

male quick connect terminals.

Operation (Delay-on-Break)

Input voltage must be applied before and during timing. Upon

closure of the initiate switch, the output relay energizes. The

time delay begins when the initiate switch is opened (trailing

edge triggered). The output remains energized during timing.

At the end of the time delay, the output de-energizes. The

output will energize if the initiate switch is closed when input

voltage is applied.

Reset: Reclosing the initiate switch during timing resets the time

delay. Loss of input voltage resets the time delay and output.
