Safety Controllers

For process and/or machine control applications requiring safety for personnel or machine, a Safety PLC- allowing for safety control and standard control- would be worth considering. By meeting rigorous standards in design and testing of hardware and software, Safety Programmable Controllers save time and money on field wiring since there is no need for safety relays. As a result, a safety system designed around a safety PLC is extremely flexible. It is easy to modify because it simply requires programming changes but does not require any wiring changes or additional relays. Once the safety system has been tested and validated, the safety program in the PLC can be locked and password protected to prevent unauthorized variations. Certain models even support integrated motion over Ethernet, and can be used to initiate safe torque-off function on various types of variable frequency drives (VFDs).
