CRITEC LAN RJ45	CRITEC® LAN RJ45 - Local Area Network Protector The CRITEC LAN RJ45 suits both 10BaseT and 100BaseT Unshielded Twisted Pair (UTP) Ethernet and Wireless networks. This protective device features a simple RJ 45 plug-in installation. State-of-the-art protection technology ensures that high speed LAN data is allowed to pass, while transients are attenuated to safe levels. Features: • Simple plug-in installation • Wide bandwidth • Compact design • 10BaseT and 100BaseT Cat5 operation Applications: • Suitable for Router, switch and Power Over Ethernet applications, up to 500mA More Information Ordering Information Part No. Description LAN RJ45 LAN RJ45, 100BaseT, Cat 5 Protector Technical CRITEC LAN PROTECTOR DATA SHEET Technical Data Sheet
CRITEC RTP 3034	CRITEC® RTP - Remote Transmitter Protector The CRITEC® RTP is designed for the protection of industrial 4-20mA loop connected transducers. The 3/4" BSP stainless steel enclosure can be installed in-line with the field conduit, or fitted directly to the spare transducer connection port. Installation is simplified as the protection circuit can be removed from the enclosure to connect field wiring to the screw terminals. The RTP employs a hybrid three stage clamping circuit to ensure the best possible protection to sensitive field equipment. Features: • 20 kA (@8/20us) Surge Rating • Flexible installation – enclosure can be installed “dead ended,” “T” configured or in-line • Stainless steel enclosure - can be used in hostile environments • Hybrid 3 stage protection – fine over-voltage protection, ensures lowest residual surge voltage reaches sensitive equipment • Optimized for protection of 2-wire industrial 4-20mA loops – suitable for exposed locations • Supports line currents up to 145mA – protects 24Vdc powered equipment Applications: Balanced pair signal lines and low voltage secondary power supply systems including: • 4-20mA loop connected equipment • 24V dc powered transducers and field equipment More Information Ordering Information Part No. Description RTP 30 34 Remote Transmitter Protector, 30V, 3/4" Technical CRITEC RTP Technical Data Sheet

CRITEC HSP/DLT Series	CRITEC® HSP/DLT Series Industrial environments are prone to dangerous and damaging transients and surges which can be induced onto signal lines as a result of lightning, power switching and electrostatic discharges. These surges and transients can cause erroneous equipment operation, or programming of industrial equipment to cause system failure. The HSP High Speed Protector (HSP) series provides transient protection to programmable logic controllers (PLCs), RS-232C, RS-423A, RS-485/422 signal lines, fire, security alarms, industrial monitoring, and control equipment. The Critec HSP High Speed Protector series has been developed to protect equipment from surge currents of up to 10kA (8/20us). The unit protects up to ten un-balanced signal lines or five balanced signal pairs. DLT Terminator For industrial and other signalling applications the DLT Data Line Terminator can be used with the HSP series where screw terminal connection is required for wire sizes up to 2.5mm2. Features: • Single and 10 pair protection for Krone-LSA disconnect blocks • Simple plug-in operation • Multi-stage protection technology • Line-to-line and line-to-ground protection Range of protectors to suit particular applications Applications: Krone-LSA Disconnect Block Series • Plugs into Krone LSA-Plus disconnect blocks • Low voltage versions for industrial signaling circuits More Information HSP Series DLT HSP Series Application Ordering Information Part No. Description Approvals HSP10 K12 Krone 10 Pair, High Speed Protector, 12V CE, C-Tick HSP10 K36 Krone 10 Pair, High Speed Protector, 36V CE, C-Tick DLT Data Line Termination (Screw terminal block for SLP/HSP) CE Krone-LSA and Krone LSA-Plus are registered trademarks of Krone GmbH, Germany Technical CRITEC HSP CRITEC Specification
