Honeywell I/O Scanner 900S75S-0360-00
Digital Input Module – AC DC Voltage type (900G04-xxsx)
The AC/DC Input Module provides sixteen individually isolated,
inputs that are powered externally. Two terminals are provided
for each circuit. AC or DC power
applied between the input terminals cause the inputs to turn
On. There is a green LED state indicator for each channel on
the module to indicate when a digital input is ON.
A green blinking status LED on the module indicates when the
module is being scanned. An amber blinking status LED
indicates when channels are forced and a red status LED when
module diagnostics exist.. Logic in the controller allows the
state to be inverted when necessary.
Requires Euro style 36-terminal terminal block.

32 Point Digital Input Module - DC Voltage type
(900G32-xxxx)
The DC Digital Input module provides 32 inputs
separated in to 2 groups of 16 channels each. Each
group has a pair of screw terminals for the COM
connection. DC power applied between the common
terminal and an input cause the input to turn ON. There is
a green LED state indicator for each channel on the
module to indicate when a digital input is ON. A green
blinking status LED on the module indicates when the
module is being scanned. An amber blinking status LED
indicates when channels are forced and a red status LED
when module diagnostics exist. Logic in the controller
allows the state to be inverted when necessary.

Relay Output Module (900H01-xxxx)
The Relay Output Module provides eight individual
galvanically isolated, electromechanical relay outputs.
Four of the outputs are Form-C, and the other four are
Form-A. Outputs are not fused in the Relay module.
Install a fuse for each output at the field device that is
appropriate for the load and the wire used.
There is a green LED state indicator for each channel on
the module to indicate when a digital output is ON.
A green blinking status LED on the module indicates
when the module is being scanned. An amber blinking
status LED indicates when channels are forced and a red
status LED when module diagnostics exist.
