Redundant I/O

SD Series redundant I/O arrangements provide enhanced availability for your most critical field

I/O.  Available for both analog and digital I/O, these redundant I/O modules protect against

common power, communications, hardware and software failures and I/O channel failures without

requiring any additional configuration.

Specifically, SD Series solutions:

• Use the extensive set of field-proven INFI 90 function code algorithms as previous generation controllers

• Use traditional INFI-Net exception reporting over redundant 100 Mbps Fast-Ethernet (PN800)

• Extend current Composer graphical design engineering tools with device management

capabilities

Further, Symphony Plus Rack and SD Series control networks, INFI-Net and PN800

respectively, can be connected via a self-configuring INFI-Net to Ethernet bridge

(IEB800) module (Figure 08). Use of this bridge makes resident data on either network available

for use in control applications, or for display in the other system.

Local and remote options

24V DC power requirements, low module power consumption, and a module temperature rating

of -40°C to +70°C (ambient) make SD Series I/O equally suited for local or remote I/O installations.

G3 coating makes SD Series I/O suitable for use in corrosive environments without requiring costly

sealed cabinets or purging systems. The software configuration is identical when configured as

either local I/O or remote I/O or mixed.

Easy expansion of existing Rack systems SD Series I/O modules are compatible with HR

Series BRC300/400/410 controllers for easy, incremental expansion of existing Rack systems.

Typical examples include expansion with remote I/O or HART enhancements to existing Rack

installations.
