• Telco Multiport Series Surge Suppressors
• Telco, Data, T1 & E1 Suppressors
• Telco M66 Series Line Suppressors
• SureLinx Series 4-20 mA Current Loop Protector

The Telco Multiport Series incorporates reliable SAD/Gas Tube protection into a field upgradeable/serviceable design. This innovative, modular design provides reliable T-1 protection in an affordable and convenient package. When remaining online matters, the Multiport Series is the ideal solution.

• Field-upgradeable to six circuits
• Connects via RJ45 (RJ48C) in and out
• Suppressor utilizes SAD and Gas Tube on each circuit
• Field-serviceable without taking remaining circuits offline
• Innovative modular design for simple upgrade and /or replacement

The Multiport Series is available with 4, 5, or 6 T-1 suppression circuits utilizing SAD and Gas Tube on each circuit. The 4 and 5 circuit models are field-upgradeable to 6 circuits, allowing customers to quickly expand capacity at sites by inserting additional modules. This unique, patent pending design is completely field-serviceable, allowing individual T-1 circuit cards to be removed and replaced in the event of damage without taking the remaining circuits offline.

The TJ Series Line Suppressors provide optimal protection for switches, PBX equipment, Channel Service Units, Time Slot Shifters, Modems, Automatic Teller Machines, Dial-Up Interface Devices, and other line-connected equipment. Prevent communication interruptions and terminations caused by transients with the TJ Series.

• Non-degrading, fast responding, low clamping SAD protection
• Models with parallel gas tube for high surge current handling
• High quality PC board construction
• Tip to ring, tip to ground, and ring to ground protection
• Hardwired, 66 Block, or plugged-in connections

The TJ Series utilizes silicon avalanche diodes (SADs) for primary line protection, supplementing SAD protection with gas tubes for higher energy handling in specific products. Suppressors provide normal and common mode protection, easy connections, and simple instructions for proper suppressor installation and correct grounding.

The M66 Series Line Suppressors provide optimal protection for a variety of line-connected equipment. Prevent communication interruptions and terminations caused by transients with the M66 Series.

• Fits all 66 type M blocks
• High quality PC board construction
• Non-degrading, fast-responding, low-clamping SAD protection

The M66 Series utilizes silicon avalanche diodes (SADs) for primary line protection. Suppression modules replace the bridge clip on M66 punch down blocks. Optional ground strap available.

The SureLinx 4-20 current loop protectors provide multi-stage capacity protection for 24 and 48 volt 4-20 mA electronics instrumentation.

SureLinx current loop protectors use a multi-stage hybrid circuit to provide a combination of high surge capability and low let-through voltages. Silicon avalanche diodes catch the leading edge of the surge and sub-nanosecond response time. Within microseconds, and impedance coordinated dual-chamber heavy-duty gas tube crowbars the surge to the ground. The protector remains in this state until the surge has safely passed and voltages return to nominal, then restores the loop to normal operations.
