INTRINSIC SAFETY
NAEV30-DI2 or DI4
Digital signals (ON/OFF)
• 2 or 4 channels, intrinsic safety digital inputs:
Proximity detectors NAMUR, contacts…
• rail mount on hat profile 35 mm
• all connections by removable screw terminals
• ready made wiring system (see option leaflet)
SPECIFICATIONS
Digital inputs
Each of the 4 x I.S. inputs can be configured independently for a
contact or a proximity detector NAMUR as per DIN 19234.
Excepted DI4C type dedicated to contacts only.
I.S. inputs
Proximity detector NAMUR as per DIN 19234 or free potential
contacts, relays, pressure or temperature switches or push
buttons in hazardous area.
Non I.S. recopy outputs
According to the type of sensor and the chosen logic: a green
LED on the front panel, in standard output, a free-potential
contact for each channel without common wire.
Optional open collector output on NAEV30-DI2.
Cut-off power : 230 VAC – 0.5 A –120 VA
Collector cut-off power:15V – 60 mA – 0.9 VA –350 Hz
Selection of the sensor type
Inductive / capacitive I.S. certified NAMUR proximity detector or
free-potential contacts.
Selection of the logic
By a mini-DIP choose of the active output in presence or lack of
target (proximity detector) or when contact is NO (Normally
Open) or NC (Normally Closed).
Fault detector
For all inputs configured as NAMUR, all models (excluding DI4C)
give a fault detector – broken line or short-circuit. In faulty case,
the green front LED switches off and the red LED corresponding
to the defective channel switches on.
Other channels are not affected.
NAEV30 series
Other models enable the control of binary outputs (1, 2
or 4) and complete ON/OFF valve function (1 output + 2
inputs).
Power supply and connections
According to model: 230 VAC (A230) or 115 VAC (A115) +/-10%
and 24 VDC +/-10% (C024) consumption 5 VA.
1 front panel yellow LED is “ON” when supply is active.
All connections by removable screw terminals.
Supply distribution by mean of a flat cable from one unit to the next
one. This flat cable is in standard delivery.
Classification for explosive areas
NAEV30 is an intrinsic safety associated apparatus.
It must be installed in safe area and connected to materials
installed in zone 0, 1 or 2 - gas (G)
or in zone 20, 21 or 22 - dust (D).
Classification according to ATEX 94/9/CE:
I/II (M1)/(1) G/D [EEx ia] IIC
Safety parameters see EC-type certificate LCIE 00ATEX 6034X
Ambient operating temperature : -20°C to +60°C
Recommended operating temperature : -20°C to +50°C
Storage temperature : -40°C to +80°C
Dimensional and mechanical
Housing for symmetric DIN rail (hat profile 35 mm as per standard
NFC63015 / EN50022) - Depth : 120 mm
Width on rail 29.5mm. Height: 90 mm – 145 mm overall including
space for cables. Minimal distance between rails: 180 mm
opposite mount.
Conditions of installation
- Mounting NAEV30 series on DIN rail must take in account thermal
dissipation and risk of overheating generated by housings installed
side by side. In case of a high concentration of NAEV30, we
recommend to leave a free space of 10 mm between each group
of 8 units (horizontal rail) and between each group of 4 units
(vertical rail).
- Mounting in a cabinet: In this case, it is recommended to close
the electrical cabinet and to ensure a circulation of fresh air even
by mean of an air conditioner to keep the inside temperature at a
level compatible with the recommended operating temperature
among the units
