Connecting Sensors and Actuators
Each module-specific data sheet indicates the appropriate Terminal Strip(s) for
that module.
Connecting Discrete Devices
VersaPoint discrete modules allow the connection of sensors and actuators in 2-
wire, 3-wire, or 4-wire technology (ability varies by module). A single Terminal
Strip can support the following connection methods:
– 2 sensors or actuators in 2-, 3-, or 4-wire technology
– 4 sensors or actuators in 2- or 3-wire technology
– 2 sensors or actuators in 2- or 3-wire technology with shielding (for analog
sensors or actuators)
The tables below summarize the connection options for 24V modules. A
connection example is given in every module-specific data sheet.
