Description:

The 'R' designation identifies modules designed for hot-swappable operation, allowing safe removal and insertion while the I/O rack remains powered. This feature ensures uninterrupted performance, as other modules in the rack continue normal operation without disruption to your process or machinery.

Modules marked with a 'C' suffix meet strict European regulatory requirements, including: Low Voltage Directive (73/23/EEC) – Ensures electrical safety. EMC Directive (89/336/EEC) – Guarantees electromagnetic compatibility.These certifications confirm the modules adhere to essential health, safety, and environmental protection standards for industrial use in the EU market.

Whether you need hot-swappable convenience ('R') or CE-compliant ('C') modules, these suffix codes help you select the right component for your application. The 'R' series minimizes downtime during maintenance, while 'C' models ensure compliance with international regulations.

With 'R' series modules, system upgrades and replacements can be performed without shutting down the entire rack—maximizing productivity. Meanwhile, 'C' certified modules provide peace of mind for operations requiring adherence to European electrical and EMC standards.
