Why Choose the Pizzato CSFS-10V120-TF4 Safety Timing Module?
The Pizzato CSFS-10V120-TF4 is a robust safety timing relay module designed for industrial automation systems requiring a fixed medium-to-long delay before safety outputs are activated or released. As part of the trusted Pizzato CSFS safety relay series, it ensures consistent timing performance for safe machine sequencing, controlled start-up logic, and reliable safety circuit operation.
This model features a fixed-time delayed-at-energizing function (TF4), meaning the timing is factory-set and not adjustable. The TF4 variant typically corresponds to a fixed delay of approximately 30 seconds (within the CSFS timing scale), making it suitable for systems where a longer safety pause is required before enabling machine operation.
With its compact DIN-rail mounting design and industrial-grade enclosure, the CSFS-10V120-TF4 integrates easily into control panels used in OEM machinery, manufacturing systems, and automation environments. It is engineered for applications where timing accuracy, functional safety, and long-term reliability are essential.
