CTI 2556-A 16-Channel Isolated Thermocouple Input Module

2556-A 16-Channel Isolated Thermocouple Input Module

The 2556-A is a high-speed 16-channel isolated thermocouple input module designed to be compatible with the 2500 Series® I/O base. The 2556-A translates millivolt level signals from the thermocouple element into a scaled temperature value. Multiple thermocouple types are supported as well as millivolt inputs.

Smart ModernizationTM

Whether you are an existing user of the 505 Series® or

looking for your next control system, CTI’s Smart

Modernization approach ensures the CTI control system you

are investing in will be around for many years to come.

Smart Modernization encapsulates our philosophical

approach to making control system advancements while

ensuring seamless transitions for our customers through the

continuous evolutionary improvement of our products.

With many 505 Series® products still in use today—some in

use for more than 30 years— the 2500 Series® allows these

customers to modernize existing controls without expensive

re-wiring, reprogramming, retraining, or product line

shutdowns.  Upgrading a control system with modern-day

replacements of old components and/or enhancing

performance with new advanced function modules — all of

which are backward compatible — mitigates risk during

migration and allows reuse of existing application programs

and hardware — reducing cost and downtime.  That’s what

we call Smart ModernizationTM.
