Module Data, Status, and Configuration
Overview This chapter examines the module's data tables and channel configuration
words.
Module Inputs
The 1769-BOOLEAN module has eight, single-ended, 24V dc sinking inputs.
Sinking describes the current flow between the I/O module and the field
device. Sinking input circuits are driven by a current sourcing field device.
Field devices supplying the positive (+V) field supply voltage when ON will
source current to the 1769-BOOLEAN module inputs.
Module Outputs
The 1769-BOOLEAN module has four, single-ended, 24V dc sourcing
outputs. Sourcing describes the current flow between the I/O module and the
field device. Sourcing output circuits supply current to sinking field devices
when ON. Field devices connected to the dc common of the field supply
voltage are sinking field devices.
