PNOZ X3 774310 Pilz Safety Relays 24VAC 24VDC 3n/o 1n/c 1so

1.Overview of the PNOZ X3 774310 Pilz

The Pilz PNOZ X774310 safety relay, part of the PNOZ X3 series with over a million units sold worldwide, features a 24 V AC/DC wide-voltage power supply, three safety normally open (NO) contacts and one auxiliary normally closed (NC) contact. It meets ISO 13849-1 PLe / SIL CL 3 emergency stop and safety door monitoring requirements with a single plug, making it an ideal partner for entry-level safety control in machinery and equipment.

Dual-channel redundancy: Two internal positive-guided relays ensure safe disconnection even if one is stuck, complying with EN 60947-5-1 for forced-guided structures. 24V AC/DC wide voltage range: The same terminal block is compatible with both 24V AC and 24V DC, eliminating the need to distinguish between on-site power connections and reducing spare parts inventory. 3s/1c contacts: Three safety normally open (N/O) momentary contacts are connected in series in a safety chain, and one normally closed (N/C) auxiliary contact provides signal feedback, ensuring reliable disconnection and alarming. Automatic/manual reset switch: A DIP switch selects automatic, monitored, or manual reset, accommodating both fast restart and manual confirmation. Inter-channel short-circuit detection: Dual-channel inputs are compared in real time to immediately disable startup if a short circuit occurs in the emergency stop button or wiring, preventing false safety. Stop Category 0: Stops upon power failure, with a typical response time of < 15 ms, meeting the rapid braking requirements of high-speed presses, robots, AGVs, and other applications.

2. Main Features
Dual-channel redundancy + positively guided contacts
Two internal positively guided relays ensure safe disconnection even if any contact is stuck, complying with EN 60947-5-1.
Wide voltage supply
24 V AC/DC universal power supply eliminates the need to distinguish between AC and DC power on-site, reducing spare parts.
Automatic/manual reset switchable
A dial switch allows selection of automatic, monitored, or manual reset, providing both a fast restart and manual confirmation. Short-circuit detection
Real-time comparison of dual-channel inputs. Startup is disabled if the emergency stop button or wiring is short-circuited, preventing false safety.
Stop Category 0
Instant stop upon power failure, with a typical response time of < 15 ms. Suitable for rapid braking applications such as high-speed presses, robots, and AGVs.
Visual diagnostics
Three LEDs on the front display the power, channel 1, and channel 2 status, respectively, for easy troubleshooting.
Seamless expansion
Can be combined with PNOZ X series expansion modules (contact, time delay) to create up to 20 safety outputs, meeting the safety chain requirements of the entire production line.
Global certifications
TÜV, CE, cULus, CCC, and KOSHA certifications ensure single-wiring export to Europe, the United States, Japan, South Korea, and Southeast Asia.
