Eaton Intrinsically Safe SPD SD07R High Bandwidth Surge Protection for Industrial Signals

Product Overview

SD07R - Intrinsically Safe Surge Protection for RS-485 & 4-20mA Loops

The SD07R is a high-performance surge protection device designed specifically to protect RS-485, RS-232 communication lines, and 4-20mA process control loops from damaging transient overvoltages and lightning-induced surges. Part of Eaton MTL's trusted SD Series, this module delivers robust protection in an ultra-slim, space-saving package ideal for DIN rail mounting in industrial control cabinets, hazardous areas, and field junction boxes.

Key Applications

Fire alarm and gas detection systems
Process I/O and shutdown systems (ESD)
Thermocouple and transmitter circuits
SCADA and industrial communication networks

Why Choose SD07R?

Designed for Critical Process Applications

The SD07R features multistage hybrid protection circuitry combining gas discharge tubes (GDT) and solid-state clamping components. This delivers both high surge handling capacity and ultra-fast response - essential for protecting expensive PLC cards, DCS I/O modules, and field transmitters.

Fused Disconnect for Easy Maintenance

Unlike standard SDX series protectors, the SD series (including SD07R) incorporates a built-in fuse holder. This allows technicians to:

Isolate the protected circuit without removing wires
Safely perform loop testing and maintenance
Protect against fault currents that could damage downstream equipment

Hazardous Area Compatible

The SD07R is BASEEFA/ATEX certified as a simple apparatus, meaning it can be installed in Zone 0, 1, and 2 hazardous areas without compromising the intrinsic safety certification of the loop.

Ultra-Slim Form Factor

At just 7mm wide, the SD07R occupies minimal panel space - a critical advantage for retrofitting surge protection into existing cabinets where space is at a premium.

Compatible Applications & Target Systems

Application	Specific Use Case
Fire & Gas Systems	Addressable loops, detector circuits
Process Control	4-20mA analog inputs from pressure/temperature transmitters
Emergency Shutdown (ESD)	Safety PLC digital inputs
Communication Networks	RS-485, RS-232, Modbus, Fieldbus
Telemetry & SCADA	Remote terminal unit (RTU) protection
Hazardous Area Barriers	Downstream of zener barriers or galvanic isolators

Ordering Information
