Description

The Pilz 774790 is the PNOZ V 30s standalone safety relay in the PNOZ X family, cataloged under the full descriptive designation PNOZ V 30s 24VDC 3N/O 1N/C 1N/O t. It is designed for E-STOP pushbutton monitoring, safety gate monitoring, and limit switch monitoring in single- or dual-channel wiring configurations. Refer to manufacturer documentation to confirm compatibility with your specific application.

This relay accepts a 24V DC supply voltage (operating range 20.4–26.4V DC) and draws 5 Watts of power. Outputs consist of Three (3) instantaneous safety contacts (N/O), one (1) instantaneous auxiliary contact (N/C), and one (1) delayed safety contact (N/O) with a delay-on de-energization time selectable across Twelve (12) steps from 0.05 to 30 seconds. Instantaneous safety output contacts are rated 8A at 24V DC (DC-1) or 8A at 240V AC (AC-1); the delayed contact is also rated 8A. The relay mounts on DIN rail via integrated fixed screw terminals and has a housing width of 90 mm.

The 774790 achieves SIL 3 / PL e / Category 4 on its instantaneous safety contacts (PFH = 2.31E-09) and SIL 2 / PL d / Category 3 on the delayed contact when delay is set below 30 seconds — making it suitable for the highest-demand safety circuit applications. Automatic or manual start modes are selectable, and the circuit includes built-in self-monitoring that verifies correct relay contact operation on every on/off cycle.

About ACME MRO Solutions

We started ACME MRO Solutions to fix something we kept running into as contractors — plants down, parts slow, surplus listings you couldn't trust. Our goal is simple: get YOU the right component fast, with an honest description, so you can get back to running.

We describe what we see. Used items show signs of use; if a part has visible wear, damage, or a missing component, the condition description will say so. We don't claim anything is tested unless we tested it — and we don't bench-test parts where testing isn't practical or revealing (feed-through modules, breakers, mechanical components). When we do test something, we'll say so explicitly.

If something is our fault, we don't work through it — we make it right. We are proud to serve American manufacturing. Your uptime is our bottom line.
