The Phoenix Contact PSR-SPP-42-230UC/URM4/4NO/2NC extension module delivers dependable signal expansion for safety systems, handling input voltages from 42 to 230 V AC/DC. Compact in design at just 22.5 mm width, it offers four normally open and two normally closed contacts for flexible integration. When combined with a PSR safety relay, it supports performance up to Category 4, PL e, and SIL 3, making it ideal for advanced machine and plant safety. Built for DIN rail mounting, this module provides a practical and space-saving way to increase contact availability in demanding industrial environments.
The PSR-SPP-42-230UC/URM4/4NO/2NC extension module enhances safety relay functionality by enabling secure processing of signals above the standard 24 V range. This makes it especially effective in applications such as furnace controls, automated machinery, and process equipment requiring strict safety compliance. The device uses force-guided relay technology to ensure consistent switching and reliable feedback. Its integrated surge protection helps extend service life under electrical stress. With short response times and high switching durability, engineers gain a straightforward solution to meet stringent safety standards while keeping installation and operation efficient.
Because it transforms complex safety requirements into simple, reliable solutions. With its wide input range and compact design, this module extends safety relay capacity without taking up valuable panel space. It’s trusted for ensuring maximum performance levels (PL e, SIL 3) while keeping installation and maintenance effortless for modern industrial systems.
It solves the challenge of safely processing signals beyond low-voltage levels. Many industrial applications demand secure control at higher voltages, and this module delivers exactly that. By providing additional force-guided contacts and integrated surge protection, it eliminates reliability concerns and ensures compliance with global safety standards in critical automation environments.

In a sheet-metal workshop, operators require instant stop functions on press brakes to avoid serious injury. By adding the extension module to the main safety relay, engineers can provide extra redundant contacts to shut down the press drive and associated hydraulics. Its fast switching and force-guided relay contacts ensure that if one channel fails, the other maintains safety. The wide input voltage range means the module can be connected directly to higher-voltage control circuits, avoiding extra converters. This guarantees reliable shutdown whenever the safety gate is opened, ensuring compliance with strict machine safety standards.
Robotic assembly cells often use safety light curtains to protect workers. When someone enters the guarded zone, all robot movement must be stopped immediately. The extension module distributes the stop signal across several drives and controllers, ensuring each axis halts simultaneously. With multiple normally open and normally closed contacts, it provides the redundancy needed to avoid partial shutdowns. Its compact DIN-rail design keeps control cabinets organized while simplifying wiring across complex systems. The quick reaction time supports coordinated emergency stops, making robotic environments safer without compromising productivity.
Industrial furnaces require strict safety interlocks on access doors to prevent exposure to high heat and live elements. The extension module allows safety circuits to operate at voltages beyond the standard 24 V, matching the higher-voltage supplies typically found in furnace installations. When the door is opened, redundant contact paths immediately disable heaters and exhaust fans. Integrated surge protection shields against electrical spikes common in such environments, reducing wear on components. This ensures operators are never exposed to dangerous conditions and production processes remain compliant with international safety standards.
Modern packaging lines run at high speed with multiple zones handling filling, sealing, and labeling. An emergency stop in one area must cascade through the entire line to prevent jams and equipment damage. The extension module provides additional outputs to expand the emergency stop network without redesigning the control system. Its rapid response and high contact durability guarantee consistent shutdown signals across all motors and actuators. By simplifying the extension of safety circuits, it minimizes downtime, ensures operator safety, and keeps the production line compliant with required safety performance levels.
