Control Version
Battery Sourced Power Module with Pneumatic Output
Ex ia IIC T4/T5/T6 Ga
Install per control drawing GE59530
as shown in figure 1 and 2
Enclosure: Type 4X, IP66 & IP67
T4(Tamb ≤ 50_C), T5(Tamb ≤ 46_C), T6(Tamb ≤ 31_C)
Temperature Range: -20_C to 50_C
Special Conditions of Use
The apparatus shall not be subjected to mechanical impacts or friction.
The piezo valve can be used with natural gas as control fluid provided that no gas-air mixtures are present in the
pressure system.
HART communication terminals (WP1-WP2) must be only connected to certified intrinsic safety equipment and this
combination must be compatible regarding intrinsic safety rules.
Battery Sourced Power Module:
The apparatus can only be powered with a module type GE57654X012 or GE57655X012
External Power:
The apparatus may be powered externally via external power module GE61615X012
Install per control drawing GE59530 which includes intrinsic safety information.

INSTALLATION MUST BE IN ACCORDANCE WITH THE NATIONAL WIRING PRACTICES OF THE COUNTRY IN USE.

BARRIERS MUST BE CONNECTED PER MANUFACTURE'S INSTALLATION INSTRUCTIONS.

INTRINSICALLY SAFE APPARATUS MAY BE CONNECTED TO ASSOCIATED APPARATUS NOT SPECIFICALLY


EXAMINED IN SUCH COMBINATION. THE CRITERIA FOR INTERCONNECTION IS THAT THE VOLTAGE (Ui) AND


THE CURRENT (Ii) OF THE INTRINSICALLY SAFE APPARATUS MUST BE EQUAL TO OR GREATER THAN THE


VOLTAGE (Uo) AND CURRENT (Io) DEFINED BY THE ASSOCATED APPARATUS. IN ADDITION, THE SUM OF


THE MAXIMUM UNPROTECTED CAPACITANCE (Ci) AND INDUCTANCE (Li) OF EACH INTRINSICALLY SAFE


APPARATUS, AND THE INTERCONNECTING WIRING, MUST BE LESS THAN THE ALLOWABLE CAPACITANCE (Co)


AND INDUCTANCE (Lo) DEFINED BY THE ASSOCIATED APPARATUS. IF THESE CRITERIA ARE MET, THEN THE


COMBINATION MAY BE CONNECTED.


FORMULAS Ui > Uo
Ii > Io
Ci + Ccable < Co
Li + Lcable < Lo
Pi > Po

RESISTANCE BETWEEN BARRIER GROUND AND EARTH GROUND MUST BE LESS THAN ONE OHM.

IF HAND-HELD COMMUNICATOR OR MULTIPLEXER IS USED, IT MUST BE APPROVED WITH ENTITY


PARAMETERS AND INSTALLED PER THE MANUFACTURER'S CONTROL DRAWING.
WARNING
THE APPARATUS ENCLOSURE CONTAINS ALUMINUM AND IS CONSIDERED TO CONSTITUTE
A POTENTIAL RISK OF IGNITION BY IMPACT OR FRICTION. AVOID IMPACT AND FRICTION
DURING INSTALLATION AND USE TO PREVENT RISK OF IGNITION.
