Schedule
 
EQUIPMENT:
Equipment and systems covered by this certificate are as follows:
 

Pulse Isolators Type 9202B1., Type 9202B2. and Type 9202B3. for rail mounting are 24V  powered 1 channel (Type 9202B.A) or 2 channel (type 9202B.B) isolating barriers, interfacing "Namur" sensors or contacts located in an explosive atmosphere.

Pulse Isolator Type 9202B.. is supplied via terminals at the front of the module, or via Power Rail Type 9400. Removable Display Module 4501 can be used for programming of the Pulse Isolator.

Ambient temperature range: -20 °C to +60 °C. 

 
CONDITIONS OF CERTIFICATION: YES as shown below:
 

If the Pulse Isolator is installed in Zone 2, the following conditions for safe use apply:

The Pulse Isolator shall be installed in an enclosure in type of protection Ex n or Ex e, providing a degree of protection of at least IP54. Cable entry devices and blanking elements shall fulfil the same requirements.

Removable Display Module 4501, when connected to the Pulse Isolator, may not be damaged and shall be free of dust and moisture.

Supply via the mounting rail is only allowed if Power Rail Type 9400 with Power Control Unit Type 9410 (Certificate of Conformity IECEx KEM 08.0025X) is used.

EQUIPMENT(continued):
 
Electrical Data

Supply (terminals 31, 32 and rear contacts): U = 19.2 ... 31.2 Vdc

Digital outputs (terminals 11, 12 and 13, 14):
Transistor output, Umax = 30 Vdc, Imax = 80 mA (Type 9202B1.)
Relay contacts, Umax = 30 Vdc or 32 Vac, Imax = 2 A (Types 9202B2. and 9202B3.)

Status output (terminals 33, 34):
Relay contacts, Umax = 30 Vdc or 32 Vac, Imax = 2 A

If the Pulse Isolator is installed outside the hazardous area, the following data for the relay contacts apply:
Umax = 30 Vdc or 250 Vac, Imax = 2 A

For all circuits above: Um = 253 Vac (max. frequency 400 Hz).

Sensor circuits (terminals 41 ... 44, 51 ... 54):
in type of protection intrinsic safety Ex ia IIC/IIB/IIA or Ex iaD, with following maximum values:
Uo = 10.6 V; Io = 12 mA; Po = 32 mW; Co = 2.0 µF (IIC) or 6.0 µF (IIB) or 18.0 µF (IIA);
lo = 260 mH (IIC) or 780 mH (IIB) or 1000 mH (IIA); Lo/Ro = 1150 µH/Ω (all groups);
for Ex iaD, the parameters of group IIB apply.

The intrinsically safe sensor circuits are infallibly galvanically isolated from each other and from the non-intrinsically safe circuits.
