TA24A5工业自动化与控制的延时继电器规格书PDF中文资料

Description

The TA Series prevents rapid recycling of a compressor. A

lockout delay is started when the thermostat opens, or input

voltage is lost. Eliminates tripped circuit breakers or blown

fuses caused by a locked rotor during short cycling. The TA

will not allow the compressor to start when the line voltage

is low. Chatter of the compressor relay is eliminated. Because

of the fast initiate time, bounce of the thermostat will not be

transmitted to the compressor relay coil. A 30 second delay

provides anti-reversing protection for scroll compressors.

Operation (Lockout)

On initial closure of the S1, the compressor relay energizes

immediately. When S1 opens or input voltage is interrupted, a

lockout time delay is initiated. During this lockout time delay,

the compressor relay cannot be energized. The low voltage

brownout) protection prevents energization of the compressor

when the line voltage is low.

Reset: The lockout time delay cannot be reset. After the time

delay is completed, the unit automatically resets.
