CTI 2556-A 16-Channel Isolated Thermocouple Input Module

DESCRIPTION

The 2556-A is a high-speed 16-channel thermocouple input module

designed to be compatible with the CTI 2500 Series® and Simatic®

505 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.

Scaling, alarm detection, filtering, peak and valley hold, and averaging

are supported on a channel-by-channel basis. All parameters may

be loaded into the module directly with relay ladder logic.

The Sixteen Channel Thermocouple Input Module is a member of

Control Technology's family of I/O modules compatible with the all

2500 Series 2500® Processors and the SIMATIC® 505 Series

programmable controllers.

The Model 2556-A is designed to translate a J, K, R, S, T, E, and L

(DIN J) thermocouple or millivolt input signal into an equivalent digital

word which is then sent to the programmable controller (PLC).

The 2556-A Thermocouple Input Module features built-in independent

internal cold junction compensation and linearization for each

thermocouple input for Types J, K, E, R, S, L, and T. No external cold

junction compensation is required.
