Siemens 3TK2827-1BB40 Siguard Safety Relay 24V 0.5-30 Sec

Siemens 3TK2827-1BB40 Siguard safety relay operates on 24 V DC and provides an adjustable time-delay range of 0.5 to 30 seconds for controlled safety-related switching sequences. It monitors inputs such as emergency-stop circuits or protective guards and issues delayed or immediate safety outputs to stop machinery in a defined manner. The device belongs to the Siemens SIRIUS safety relay family and is commonly wired into control cabinets for applications that require timed release of locking devices, delayed enabling of restart, or sequenced shutdown of drives. Its compact housing mounts on standard DIN rails and carries the necessary safety approvals for use in functional-safety systems up to the performance levels specified in the product documentation.
