Scanner 2 Module (S75/S75S only)
900S75, Scanner 2 Module is shown in Figure 16
The dual ports provide redundancy through the 2 CPUs. Features at the
front of the module include:
LED status/diagnostic indicator for scanner functions.

Input/Output Modules
I/O module types:

16 point high level analog input module: each point is configurable for V or mA. Point-to-point
galvanic isolation, chassis to input galvanic isolation.

4 point galvanic isolated analog output module: Supports
from 0 to 20mA each, chassis to output galvanic
isolation.

8 or 16 point analog output module: Supports from 0 to
20mA each. Galvanically isolated in groups of 4
channels, galvanically isolated chassis to output
channels.

16 point digital input modules: Contact closure type, DC
voltage and AC voltage types. Galvanically isolated
chassis to input.
 32 point digital input module: DC voltage. Galvanically
isolated in two groups 1-16, 17-32. Galvanically isolated
chassis to input channels.

8 point AC (sourcing type) or 16 point DC digital output
modules (sinking type). Galvanically isolated output
channels to chassis and channel to channel in two groups.
 32 point digital output: DC voltage (sourcing type).
Galvanically isolated output channel to chassis and
output to output in two groups.

8 point relay output module: four form C type and four
form A type relays. Galvanically isolated output to
chassis and output to output.

8 point Universal Analog Input module. Galvanically
isolated input to chassis and input to input. With the
exception of RTD types which has four groups of
isolation 1-2,3-4,5-6,7-8.

4 channel Pulse/Frequency/Quadrature I/O module. Galvanically isolated channel to chassis.

16 Channel Safety Universal Input/Output Module Galvanically isolated Input/Output to
Chassis.
