• Ex ia IIC T4
• 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, Division2,
Groups A, B, C & D, Class II, Division2,
Groups F & G, Class III, Division1
• Enclosure: IP66/IP67 and Type 4X
• Temperature Code: T4
• Ambient Temperature: –50 to 70°C
Note 2. Output Parameters
• Sensor Circuit (Terminals: 1 to 5)
Uo = 6.6 V, Io = 66 mA,
Po = 109 mW, Co = 22 μF,
Lo = 8.1 mH
• The above parameters apply when one of
the two conditions below is given:
- the total Li of the external circuit (excluding
the cable) is < 1% of the Lo value or
- the total Ci of the external circuit (excluding
the cable) is < 1% of the Co value.
• The above parameters are reduced to 50%
when both of the two conditions below are
given:
- the total Li of the external circuit (excluding
the cable) is ≥ 1% of the Lo value and
- the total Ci of the external circuit (excluding
the cable) is ≥ 1% of the Co value.
• The reduced capacitance of the external
circuit (including cable) shall not be greater
than 1μF for Group IIB and 600nF for Group
IIC.
Note 3. Installation
• Installation should be in accordance with
Canadian Electrical Code Part I and Local
Electrical Code.
• The Hand Held Terminal must be CSA
certified.
• Do not alter drawing without authorization
from CSA.
• The instrument modification or parts
replacement by other than authorized
representative of Yokogawa Electric
Corporation is prohibited and will void
Canadian Standards Intrinsically safe and
nonincendive Certification.
