2-wire sensor module (2WSNS)
The 2-Wire Sensor Module (2WSNS) is designed to accept 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
®
. 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: All components located in the hazardous area must be third-party certified and have
appropriate entity parameters.
NOTE: More than one module is used to continue connections. See "Module configuration chart"
later in this chapter.
