a) CSA Intrinsically Safe Type/Non-incendive

Type

Caution for CSA Intrinsically safe type. (Following

contents refers “DOC No. ICS008-A13 P.1-1 and

P.1- 2”)

Note 1. Model YTA110/CU1, YTA310/CU1 and

YTA320/CU1 temperature transmitters are

applicable for use in hazardous locations:

Certicate 172608-0001053837

[For CSA C22.2]

• Ap

plicable Standard: C22.2 No.0,

C22.2 No.0.4, C22.2 No.25, C22.2 No.94,

C22.2 No.142, C22.2 No.157, C22.2 No.213

• Intrinsically Safe for Class I, II, III, Division 1,

Groups A, B, C, D, E, F & G.

• Non-incendive for Class I, II, Division 2, Groups

A, B, C, D, F & G, Class III, Division 1.

• Encl. “Type 4X”

• Temperature Class: T4

• Ambient temperature: –40 to 60°C

Note 2. Entity Parameters (Electrical/Nonincendive

eld wiring parameters)

• [Supply Circuit]

Vmax = 30 V, Imax = 165 mA, Pmax = 0.9 W,

Ci = 18 nF, Li = 730 μH

• [Associated apparatus]

Voc ≤ 30 V, Isc ≤ 165 mA, Pmax ≤ 0.9 W

• [Sensor Circuit]

Voc = 9 V, Isc = 40 mA, Po = 90 mW,

Ca = 1 μF, La = 10 mH

Note 3. Installation

• All wiring shall comply with Canadian Electrical

Code Part I and Local Electrical Codes.

• For the sensor circuitry, the above parameters

for sensor circuit must be taken into account.

• Dust-tight conduit seal must be used when

installed in class II and III environments.

• In any used safety barrier, output current must

be limited by a resistor 'R' such that Isc=Voc/R.

• The safety barrier must be CSA certied, and

the input voltage of the barrier must be less

than 250Vrms/Vdc.

• For non-incendive type, general purpose

equipment must be CSA certied and the

equipment which have non-incendive eld

wiring parameters.

• The instrument modication or parts replacement

by other than authorized representative of

Yokogawa Electric Corporation is prohibited

and will void Canadian Standards Intrinsically

safe and nonincendive Certication.
