ABB arc protection relay TVOC-2-240 1SFA664001R1001 can reduce arc fault

Description

TVOC-2-240 common relay is single channel input and output. In case of fuse welding of relay contacts, short circuit of transistors or electrical conductors, dangerous conditions may occur.
The safety relay is a dual channel input, TVOC-2-240 dual relay output, gold-plated contact, to avoid failure of the relay to cut off the output.

If the contactor has contact fusion welding, its auxiliary contact is connected with the safety relay, which can feed back the fault, and restart after timely elimination.
The two input channels must be opened at the same time, and TVOC-2-240 must be closed at the same time before the safety relay can be activated.
The safety relay is mainly used together with safety input (such as safety emergency stop, safety detection door switch, safety light curtain, etc.) products to monitor whether the state of safety input is normal, and ensure reliable cut-off output when the input is abnormal.
ABB Sentry safety relay is applicable to general mechanical equipment, robot integration, 3C equipment, packaging, automobile production line and parts production line, pharmaceutical machinery, wind power master and other mechanical equipment.
At present, ABB Sentry series has 4 series including BSR, SSR, TSR and USR, 14 models, which can be freely selected according to different customer needs, and DIN rail installation.
