The PNOZ s5 timer relay, manufactured by Pilz, is a versatile base unit commonly used in industrial safety applications. The PNOZ s5 is primarily used as a safety relay, which means it monitors safety-related inputs from devices such as emergency stop buttons, safety switches, light curtains, and safety mats. The relay typically offers adjustable delay times, allowing users to set the delay period according to the specific needs of their application.
This feature specifically refers to the capability of the relay to delay the de-energisation (turning off) of its output contacts after the input signal (e.g., from a safety device) has been de-energised. http://www.pilz.com In practical terms, when the safety input is released or deactivated, the PNOZ s5 can maintain its output (contacts) in the energised state for a specified delay period before it finally de-energises the output.
Delay-on de-energisation is useful in applications where a safety function needs to remain active for a brief period after the safety signal is no longer present. For example, this delay can allow time for a machine to safely stop or for a process to complete before power to a hazardous area is completely cut off.
The PNOZ s5, like other Pilz safety relays, complies with international safety standards such as EN ISO 13849-1 and EN/IEC 62061. These standards ensure that the relay meets specific safety integrity levels (SIL) or performance levels (PL), depending on the application requirements. Safety solutions provider since 2011, We offer Pilz.
The PNOZ s5 timer relay is designed with delay-on de-energisation functionality to enhance safety in industrial environments by ensuring controlled shutdown sequences and safe operation of machinery and equipment. Its versatility and adherence to safety standards make it a reliable choice for integrating safety functions into automated systems effectively.
