Environmental Sensors for E-2D/5D/16D/16DEL
Intrinsically Safe Barrier
Zener Barrier – Intrinsically Safe Barrier
- Limits the amount of energy allowed to pass into a hazardous area, which inhibits ignition in flammable atmospheres.
- Electrically isolates pressure and level transmitters from unregulated circuits for intrinsically safe applications.
- Compatible with E-ULT25IS Intrinsically Safe Ultrasonic Level Transmitter
- Compatible with E-PSTxxxIS Intrinsically Safe Pressure Sensor Transmitter
- Requires the ES420MA-24V to operate with E-2D/5D/16D.
- Transmitter Voltage:
- 16.2 V @ 20 mA with 250Ω load (negative w.r.t. earth)
- 11.0 V @ 20 mA with 500Ω load (negative w.r.t. earth).
- Load Resistance: 0 to 500Ω
- Terminals: Accommodate up to 2.5 mm² stranded or single-core.
- Safety Description: 28 µV, 300Ω, 93 mA
- DIN-rail mountable.
