The WLTS Current Loop Adaptor reads temperature and pressure values from a connected WLTS, converting to two channels of 4-20 mA current outputs.
The WLTS Current Loop Adaptor is rated IP 65 (dust-proof, water-resistant, can not be submerged). It is vented, with a Gore filter where it is open to the atmosphere as a moisture barrier. An LED indicates operation status or error. The cable lead to connect to your user supplied equipment is 3 m (10 ft) in length.
There are 3 operation modes for the WLTS Current Loop Adaptor. The slide switch (SW S1) is used to set the mode. Each of these modes will be discussed in more detail in this User Guide.
SW=1, User Operation Mode
SW=2, WLTS Configuration Mode
SW=3, WLTS Current Loop Adaptor Configuration Mode
Power to the WLTS Current Loop Adaptor must be turned off when switching between modes.
