Description
The I/O Scanner 2 module resides in a remote I/O rack
along with its I/O in a Redundant Controller System. The
Scanner 2 has two I/O connections I/O A is connected to
CPU-A and I/O B is connected to CPU-B in the
Honeywell Digital Input, 120/240 VAC, (16 channel)900G03-0202
I/O Scanner 2 Module (900S75x-xxxx)
The I/O Scanner 2 module resides in a remote I/O rack
along with its I/O in a Redundant Controller System. The
Scanner 2 has two I/O connections I/O A is connected to
CPU-A and I/O B is connected to CPU-B in the
Redundant Controller rack. The scanner 2 collects data
from the Input modules populated in its remote rack and
communicates the information to the Lead controller.
Output data is sent from the Lead controller to the
Scanner 2 module which in turn sends the data to
appropriate output module. Data exchanges are
synchronous with the controller scan time to maintain
deterministic operation. Diagnostic status of I/O modules
is also monitored and reported to the controller when detected.
The Rack address of a Scanner 2 module is set via
switches on the module. Connection to both of the
redundant controllers is made using both ports, each
conforming uses IEEE 802.4 Ethernet 100base TxPhysical Layer. An external Ethernet switch is required
when multiple I/O scanners are used with a single
controller. Scanner modules do support removal and
insertion under power.
Type I/O Scanner
Status indicators Scanner: Red/Green LED indicates mode or error
I/O A Port: Green and Yellow LEDs indicate receive/transmit
I/O A Port: Green and Yellow LEDs indicate receive/transmit
Power supply loading 5V; 770mA max
Redundant Switch Module (RSM) (900RSM-xxxx)
The Redundant Switch Module resides in a ControlEdge
HC900 Redundant controller rack and interfaces with
both CPUs of a redundant system and indicates which
CPU is functioning as the Lead controller and which is the
Reserve. A key switch on the module sets the mode of
both the Lead and Reserve controllers, guaranteeing
synchronization of CPUs. A momentary contact position
of the key switch allows the user to switch the Lead
control function from CPU-A to CPU-B or vice versa.
The RSM module supports insertion and removal
under power.

Power Supply Loading 5V; 22mA max
Power Status Module (PSM) (900PSM-xxxx)
The Power Status Module resides in a local or remote I/O
rack containing redundant power supplies. The PSM and
second power supply are contained in a rack extension
assembly adjacent to the power supply slot position. The
PSM module is positioned in a dedicated slot between
the two power supplies.
Redundant power and the PSM may be used with a
Controller rack with local I/O, a Scanner 1 rack with
remote I/O controller racks of non-redundant systems and
a Scanner 2 rack with remote I/O racks of redundant
systems.
Directional indicators on the module indicate
when both voltage sources of the power supply
are operating properly.
