2.9.2 CSA Certication
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
Certicate: 1606623

• 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 specied.
• 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 specied.
• 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 certied.
• 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 modication 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 Certication.
