Explosion Proof Local Control Stations (LCS)
Local control stations in hazardous classified areas are the direct interface between plant personnel and motor-driven equipment. Every pushbutton, selector switch, emergency stop, and indicator lamp must be housed in a certified enclosure that eliminates ignition risk in the surrounding explosive atmosphere. Team Switchgear and Control LLC manufactures custom ATEX and IECEx certified explosion proof local control stations (LCS) in Dubai built to your exact control philosophy, process requirements, and area classification.

Explosion Proof Local Control Stations (LCS) Zone 1 & Zone 2
Standard LCS Configuration Options
Every LCS we supply is custom-designed to the client’s control and instrumentation philosophy. Standard configurations include:
- Start / Stop 2-pushbutton LCS for single motor control
- Start / Stop / Emergency Stop 3-element LCS with IEC-compliant red E-stop mushroom head
- Forward / Reverse / Stop 3-pushbutton LCS for reversible motor control
- Hand / Off / Auto (HOA) selector switch LCS for manual/auto mode selection
- Start / Stop + Run / Fault Indication with green and red LED/lamp indicators
- Multi-function LCS combining motor start/stop, process valve open/close, and local indication in a single enclosure
- ATEX Zone 0 certified intrinsically safe pushbutton stations for use at the process interface in Zone 0 locations
Enclosure Options
- GRP (glass reinforced polyester) lightweight, corrosion-resistant, ideal for offshore and coastal environments
- Cast aluminium standard for most onshore Oil & Gas applications
- Stainless steel 316L for highly corrosive or hygiene-sensitive environments (chemical plants, food & pharma)
- All enclosures rated IP66 as standard, IP67 optional
- BARTEC, Pepperl+Fuchs, or R.Stahl certified operators and enclosures available
Compliance and Certification
- IEC 60079-1 (Ex d flameproof enclosures)
- IEC 60079-7 (Ex e increased safety enclosures)
- ATEX Directive 2014/34/EU Category 2G (Zone 1/2)
- IECEx certification accepted by ADNOC, Aramco, QatarEnergy, PDO
- IP66 / IP67 ingress protection
- Available with NEC 500 UL-listed operators for US-specification projects
Can you supply LCS with both local and remote control capability?
Yes. We regularly supply LCS units with an integral HOA (Hand/Off/Auto) selector switch that enables the operator to select between local manual control at the station and remote control from a DCS, PLC, or MCR. The HOA switch in the ‘Auto’ position passes control to the remote system; in ‘Hand’ position, the local pushbuttons are active. Feedback signals (running, tripped, valve position) can be provided via Ex i (intrinsic safety) 4-20mA loops or digital I/O.
What is your lead time for custom explosion proof LCS?
Standard 2–3 element LCS units (start/stop, E-stop) in GRP or aluminium Ex d enclosures are typically available within 3–6 weeks from approved drawings. More complex multi-function stations with custom operators, indicators, and instrument interfaces require 6–10 weeks. Rush delivery can be discussed depending on component availability.
