Protect your 4-20mA Current Loops and Low Speed Data Circuits.

Typically found in industrial environments, 4-20mA and Low Speed Circuits are often used for sending and receiving signals for data collection.

These signal systems typically monitor or control such processes as measurements of pressure, temperature moisture, water flow and water levels. In many cases…these low speed signals are 4-20mA circuits.

Many of these circuit types can be found in service anywhere from aggregate plants and waste water treatment plants to parking lots as well as other applications.

Like other data transmission circuits these Low Speed Circuits are highly sensitive. Care should be taken to protect against damaging transient voltage that can occur from weather or internally related occurrences.

Reduce and prevent system disrupts and equipment damage.

Don't use just any surge protector gear. Use gear that deliver results.

Unmatched Quality and Performance Designed For 4-20mA Current Loops

If your business or facility depends on the use of sensor devices including leak detectors, flow meters and transducers (among others)…placing the right surge protective gear between the sensors and your equipment is critical for maintaining your systems smooth operation.

By protecting your Low Speed Data circuits, equipment life is typically extended, maintenance costs reduced and increased productivity can result. Reduction or prevention from catastrophic event damage (lightning) can be mitigated if not eliminated.

If you demand protection results for your Low Speed Data Circuits…our surge protector models are the right gear for you.

Our units are hybrid-designed series wired devices. They provide true Discrete All-Mode Protection and include our Optimal Response Circuitry ™.

All suppression circuits are encapsulated in our high dielectric compound to assure long component life and protection from the elements and vibration.

This combination of design techniques provides your protected equipment with some of the lowest let-through voltage of any 420 mA or low speed data surge protector on the market.

Operating voltages range from 5 to 140 Volts with maximum data rates of up to 2Mbps.

All of our units are high quality and high performance gear.

All units are backed with a 25 Year "No Hassle" Warranty.
