2-Wire Sensor Module (2WSNS)
The 2-Wire Sensor Module (2WSNS) is designed to accept up to 12 sensor inputs per module,
and the system as a whole can accept a total of 36 sensors (3 modules with 12 inputs each).
The 2WSNS only supports standard sensors, and does not accept inputs from BRITESENSORs®.
The 2WSNS Sensor Module can also support devices defined as Simple Apparatus. Refer to the
diagram below to identify some of the standard sensors that can be used with this module.

NOTE:
Standard sensors do not use digital data. They operate like ON–OFF switches, which are
closed when no liquid is present and open when a liquid is detected.
NOTE:
Jumpers need to be present in positions that are not occupied by sensors as shown above.
NOTE:
All components in the hazardous area must be Third Party Certified and have appropriate
Entity Parameters. (See Control Drawing 000-1722 for further information.)
NOTE
: UDP sensors (FMP-XXX-U) are supported on the Probe Module but are not supported on
the 2-Wire Sensor module.
