Siemens 3TK2810-0BA01 SIRIUS Safety Relay Standstill Monitoring
Siemens 3TK2810-0BA01 SIRIUS safety relay for standstill monitoring.
The Siemens 3TK2810-0BA01 is a SIRIUS safety relay designed for safety-oriented standstill monitoring. This basic unit operates on DC 24V and features screw terminals. It provides 3 normally open (NO) instantaneous EC contacts and 1 normally closed (NC) EC contact, along with 0 delayed EC contacts and 0 SC contacts. It supports auto-start and reaches a maximum error category of 4 according to EN 954-1, maximum PL according to EN 13849-1: e, and maximum SIL according to IEC 61508: 3.
This safety relay is crucial for applications where preventing unexpected machine movement is a critical safety requirement. It is commonly used in conjunction with speed sensors or encoders to ensure machinery has come to a complete stop before personnel can access hazardous areas, such as in conveyor systems, processing equipment, and machine tools.
