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

[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 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.
