00825-0100-4101, Rev EA June 2010

Rosemount 2051

I7 IECEx Intrinsic Safety Certification No. IECExBAS08.0045X Ex ia IIC T4 (–60 ≤ Ta ≤ +70 °C)

1180

Table 3. Input Parameters

Ui = 30V

Ii = 200 mA

Pi = 1.0W

Ci = 0.012 µF

Special Conditions for Safe Use (X):

When the optional transient protection terminal block is installed, the apparatus is not capable of withstanding the 500V insulation test required by Clause 6.3.12 of IEC60079-11. This must be taken into account when installing the apparatus.

E7 IECEx Explosion-Proof (Flame-Proof)

Certification No. IECExKEM08.0024X Ex d IIC T6 (–50 ≤ Ta ≤ 65 °C) Ex d IIC T5 (–50 ≤ Ta ≤ 80 °C)

1180

Vmax = 42.4 V dc

Special Conditions for Safe Use (X):

1.Appropriate ex d blanking plugs, cable glands, and wiring needs to be suitable for a temperature of 90 °C.

2.This device contains a thin wall diaphragm. Installation, maintenance and use shall take into account the environmental conditions to which the diaphragm will be subjected. The manufacturer’s instructions for maintenance shall be followed in detail to assure safety during its expected lifetime.

3.The 2051 does not comply with the requirements of IEC 60079-1 Clause 5 for flameproof joints. Contact Emerson Process Management for information on the dimensions of flameproof joints.

N7 IECEx Type n

Certification No. IECExBAS08.0046X

Ex nAnL IIC T4 (–40 ≤ Ta ≤ +70 °C)

Ui = 42.4 Vdc max

Special Conditions for Safe Use (X):

When the optional transient protection terminal block is installed, the apparatus is not capable of withstanding a 500V r.m.s. test to case. This must be taken into account on any installation in which it is used, for example by assuring that the supply to the apparatus is galvanically isolated.
