Intrinsically Safe Signal Conditioner

The Intrinsically Safe Signal Conditioner KFD2-STC5-1.2O is a high-reliability isolator for safe signal transmission from hazardous to safe areas. Designed for ATEX and IECEx Zone 0/20 use, it supports analog signal loops, ensuring galvanic isolation between input, output, and power supply. This signal conditioner is perfect for integrating 2-wire transmitters and active sensors into control systems in oil & gas, chemical, and process automation environments.

Supporting 4–20 mA analog loops with loop-powered operation, the device does not require an external power source. It features a slim DIN rail design, ideal for compact control cabinets, and delivers stable, maintenance-free signal conditioning in extreme industrial conditions. This makes it a go-to solution for isolating field instrumentation and ensuring signal integrity in hazardous locations.

FAQs:

Can this conditioner be used in Zone 0?
Yes, it is certified for ATEX and IECEx Zone 0/20 environments.

Is it compatible with 2-wire transmitters?
Yes, it’s designed to interface safely with 2-wire field devices.

Does it require a power supply?
No, it operates passively from the signal loop.

What kind of isolation does it provide?
It provides galvanic isolation between input, output, and power.

Is this a Zener barrier?
No — this is an isolated signal conditioner, also known as an isolated barrier. It offers intrinsic safety by isolating the hazardous and safe area circuits without requiring grounding, unlike Zener barriers.

When should I use an isolated barrier instead of a Zener barrier?

Use isolated barriers like this when:

• You need galvanic isolation between field and control systems

• Grounding is not possible or practical

• You require signal accuracy (4–20 mA loops, PLCs, SCADA)

• You’re operating in Zone 0/20 environments
