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.

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.
