About the Siemens 6ES7492-1BL00-0AA0
The Siemens 6ES7492-1BL00-0AA0 is the 48-pole S7-400 front connector with spring-loaded contacts; the 6ES7492-1AL00-0AA0 has screw contacts and the 6ES7492-1CL00-0AA0 takes crimp contacts. Siemens's data sheet gives only its weight, about 194 g, and marks it as a spare part. SiePortal shows its product cancellation on 1 October 2025, a year before the screw and crimp versions, and names the 6ES7492-1AL00-0AA0 and 6ES7492-1CL00-0AA0 as alternatives.
What is the 6ES7492-1BL00-0AA0 used for?
It carries the field wiring onto an S7-400 signal module: the cables land on the connector, which plugs onto the module's front.
Lifecycle and successor
Discontinued.
