Product catalog summary
Introduction
Tapeswitch Corporation offers a variety of fail-safe interface controllers designed to connect safety devices such as ribbon switches, safety mats, sensing edges, and bumpers to machine or process controls. These controllers ensure safety by adhering to international safety standards and are ideal for high-risk automation and machine control applications.
Using Controllers in Safety Applications
The fail-safe concept is essential for machinery safety, involving continuous monitoring of sensor status to ensure any failure results in a safe condition. The system employs a 4-conductor fail-safe concept where a constant current keeps the relay coil energized, and any sensor actuation or failure de-energizes the relay, halting the machine.
PRSU Control Units
PRSU units are designed for high-risk applications, meeting safety category 3, PLd as per EN ISO 13849-1. They feature redundant safety output relays, self-monitoring capabilities, and are available in DIN rail-mounted packages. They support both manual and automatic reset modes and are compatible with various Tapeswitch sensing products.
PSSU Control Units
PSSU controllers are suitable for high-risk automation, exceeding category 3 requirements of EN 954-1. They offer redundant safety output relays and self-monitoring features. Available in both wall and DIN rail mounting models, they support manual and automatic reset modes.
PSSR/2 Control Unit
The PSSR/2 unit is compact and designed for use with Tapeswitch pressure-sensitive sensors. It meets EN13849-1:2006 PLd and EN62061 SIL2 standards, offering manual or auto reset functions and operating from 24 VDC. It includes end-of-line resistor monitoring and is suitable for various sensor types.
PCU Programmable Control Units
PCU units are modular safety controllers capable of monitoring multiple safety sensors. They support complex logical configurations via PC software and offer features like muting, timers, and counters. The PCU series meets SIL3 standards and is designed for easy configuration and maintenance.
Conclusion
Tapeswitch's range of fail-safe controllers provides robust solutions for ensuring machinery safety in high-risk environments. They comply with international safety standards and offer flexible installation options, making them suitable for a wide range of industrial applications.

USING CONTROLLERS IN SAFETY APPLICATIONS Understanding the fail-safe concept Tapeswitch sensing mat, edges, and bumpers often provide the first-line of protection for personnel and equipment. They are highly sensitive and feature press-at-any-point actuation. Properly installed and connected, they continuously monitor contact. However, to properly function as safety devices, they must be installed with a fail-safe monitoring circuit as shown below or with an equivalent fail-safe methodology. Tapeswitch Controllers Employ this Fail-Safe Concept. Understanding and Implementing the 4 conductor fail-safe...
