INTRINSIC SAFETY WIRING DIAGRAMS - MODEL 1XSWLL

(Use Class 2 or SELV Power Supply Only)

Model 1XSWLL

 is intended for direct connection to a PLC or DCS discrete input, or other suitable load (see graph 1, page 15). Power is 

obtained and the discrete switch signal is provided by the same two-wire connection. Polarity must be observed. (refer to Table 2, page 6) 

for switch ratings. 

DO NOT CONNECT MODEL 1XSWLL DIRECTLY TO A POWER SUPPLY WITHOUT A SUITABLE LOAD IN SERIES WITH THE 

SWITCH.

 

For 1XSWLL models, only one conduit opening is required.  The unused conduit opening must include an explosion-proof/flameproof plug, 

made from a corrosion-resistant material, suitable for all gas and dust groups as listed on the nameplate.  Blanking elements from factory 

have been tested with the enclosure as an assembly and carry no markings.

SELECTING AN INTRINSIC SAFETY BARRIER (Model 1XSWLL)

For Intrinsically-Safe (I.S.) installations, please reference the Control Drawing UE 62174–64 for Intrinsic Safety entity parameters and wiring 

information (https://www.ueonline.com/support/product-drawings/). Model 1XSWLL must be wired to an approved I.S. galvanically isolated 

barrier for Zone 0 EPL Ga and Class I, Division 1 classifications. The information provided is for reference only and is intended to act as a 

guide in the selection of a suitable I.S. Barrier. 

SUBSTITUTION OF COMPONENTS MAY IMPAIR INTRINSIC SAFETY.

Installation of Intrinsically-Safe circuits must be performed in accordance with the requirements of the government and/or other local 

authority having jurisdiction. System components and installation methods must be approved by the appropriate recognized approval 

authority.

There are two general types of I.S. Barriers, shunt diode (passive) safety barriers and transformer isolated barriers. Shunt diode safety 

barriers are not recommended for use with model 1XSWLL.

Transformer Isolated Barriers:

Due to the unique method by which the model 1XSWLL operates, a specifically designed isolated barrier must be used. Any safety barrier 

that adheres to NAMUR standard EN 60947-5-6 for proximity and dry contact switches may be used to achieve intrinsic safety with the One 

Series model 1XSWLL.

Recommended NAMUR standard transformer isolated intrinsic safety barriers:

 

Fuchs models KCD2-SR-Ex1.LB and KFD2-SR2-Ex1.W.LB

Figure 4 (page 6) shows a typical wiring scheme depicting model 1XSWLL connected to a programmable logic controller (PLC), distributed 

control system (DCS) or other logic solver discrete input.
