2.9.2 CSA Certification
a. CSA Intrinsically Safe Type
Caution for CSA Intrinsically safe and
nonincendive type. (Following contents refer to
“DOC No. ICS013-A13”)
Note 1. Model EJX/EJA-E Series differential,
gauge, and absolute pressure transmitters
with optional code /CS1 are applicable for
use in hazardous locations
Certificate: 1606623
[For CSA C22.2]
• Applicable Standard: C22.2 No.0, C22.2
No.0.4, C22.2 No.25, C22.2 No.94, C22.2
No.157, C22.2 No.213, C22.2 No.61010-1,
C22.2 No.60079-0
• Intrinsically Safe for Class I, Division 1,
Groups A, B, C & D, Class II, Division 1,
Groups E, F & G, Class III, Division 1
• Nonincendive for Class I, Division 2, Groups
A, B, C & D, Class II, Division 2, Groups E, F
& G, Class III, Division 1
• Enclosure: NEMA TYPE 4X
• Temp. Code: T4
• Amb. Temp.: –50* to 60°C
* –15°C when /HE is specified.
• Process Temperature: 120°C max.
[For CSA E60079]
• Applicable Standard: CAN/CSA E60079-11,
CAN/CSA E60079-15, IEC 60529:2001
• Ex ia IIC T4, Ex nL IIC T4
• Ambient Temperature: –50* to 60°C
* –15°C when /HE is specified.
• Max. Process Temp.: 120°C
• Enclosure: IP66/IP67
Note 2. Entity Parameters
• Intrinsically safe ratings are as follows:
Maximum Input Voltage (Vmax/Ui) = 30 V
Maximum Input Current (Imax/Ii) = 200 mA
Maximum Input Power (Pmax/Pi) = 0.9 W
Maximum Internal Capacitance (Ci) = 10 nF
Maximum Internal Inductance (Li) = 0 µH
• Type "n" or Nonincendive ratings are as
follows:
Maximum Input Voltage (Vmax/Ui) = 30 V
Maximum Internal Capacitance (Ci) = 10 nF
Maximum Internal Inductance (Li) = 0 µH
• Installation Requirements
Uo ≤ Ui, Io ≤ Ii, Po ≤ Pi,
Co ≥ Ci + Ccable, Lo ≥ Li + Lcable
Voc ≤ Vmax, Isc ≤ Imax,
Ca ≥ Ci + Ccable, La ≥ Li + Lcable
Uo, Io, Po, Co, Lo, Voc, Isc, Ca and La are
parameters of barrier.
Note 3. Installation
• In any safety barreir used output current
must be limited by a resistor 'R' such that
Io=Uo/R or Isc=Voc/R.
• The safety barrier must be CSA certified.
• Input voltage of the safety barrier must be
less than 250 Vrms/Vdc.
• Installation should be in accordance with
Canadian Electrical Code Part I and Local
Electrical Code.
• Dust-tight conduit seal must be used when
installed in Class II and III environments.
• The instrument modification or parts
replacement by other than authorized
representative of Yokogawa Electric
Corporation and Yokogawa Corporation
of America is prohibited and will void
Canadian Standards Intrinsically safe and
nonincendive Certification.
