Description
Rotex ATEX Ex ia Intrinsically Safe Coil – IV 14mm Low Power
The Rotex IV is a low-power ATEX and IECEx intrinsically safe solenoid coil designed for hazardous-area solenoid valve applications where electrical power available through an intrinsic safety barrier or isolator is limited.
Operating from a nominal 24V DC supply, the coil incorporates a booster circuit to provide reliable initial solenoid actuation while reducing holding power to less than 0.75 Watts.
Featuring a 14mm bore, aluminium housing and IP67 protection, the Rotex IV provides a compact intrinsically safe operator for compatible Rotex solenoid valve assemblies.
Coil Specification
Coil series: Rotex IV
Type: Intrinsically safe low-power coil
Nominal voltage: 24V DC
Power: <0.75 Watts
Bore: 14mm
Housing: Aluminium
Ingress protection: IP67
Booster Circuit
A key feature of the Rotex IV is its integrated booster circuit.
The booster provides the electrical characteristics required for initial solenoid actuation before reducing the power required during holding.
This allows the operator to achieve reliable valve switching while maintaining very low continuous electrical consumption, making it particularly suitable for intrinsically safe hazardous-area control circuits.
Operating Parameters
Nominal voltage: 24V DC
Minimum operating voltage: 14V DC
Minimum operating current: 23mA
Drop-out voltage: 8V DC
Drop-out current: 5mA
Power consumption: <0.75W
These operating characteristics are particularly important when selecting the associated intrinsically safe barrier or galvanic isolator.
Electrical Connection
Conduit entry:
M20 × 1.5
Entry orientation:
Vertical
Housing:
Aluminium
Protection:
IP67
ATEX & IECEx Certification
IECEx certificate:
IECEx BAS 12.0128X
ATEX certificate:
Baseefa 12ATEX0243X
Intrinsically Safe Installation
This coil is intended to operate as part of a correctly designed intrinsically safe electrical circuit.
The associated barrier or galvanic isolator needs to provide sufficient voltage and current for the coil's starting requirements while remaining within the certified intrinsic safety parameters for the complete installation.
Typical Applications
Suitable for compatible Rotex solenoid valves used in hazardous-area process control, oil and gas installations, chemical and petrochemical processing, process skids, refineries, tank farms, offshore equipment and intrinsically safe pneumatic control systems.
Why Choose the Rotex IV Coil?
The major advantage of the Rotex IV is its combination of intrinsic safety and exceptionally low holding power.
The integrated booster circuit allows the coil to provide the initial energy required to switch a compatible solenoid valve before reducing consumption to less than 0.75W, making it particularly useful where available power through an intrinsically safe barrier is restricted.
