CHAPTER 1. OVERVIEW 1.0. Product Summary The CTI 2559-TC Eight-Point Thermocouple Module is a member of Control Technology’s family of I/O modules compatible with the 505 programmable controllers. It is designed to SIMATIC® translate a J, K, T, E, R, S, N thermocouple or millivolt input signals from the thermocouple element into an equivalent digital word which is then sent to the programmable controller (PLC).
When module SCALING is disabled, data is reported as engineering units to the PLC as follows: Thermocouple Mode, digital word (WX) = Degrees x 10 Millivolt Mode, digital word (WX) = -10,000 to +10,000 CTI 2559-TC Installation and Operation Guide...

The 2559-TC uses the overrange error code, 32765, to indicate an open thermocouple. An open thermocouple condition will report within 200 milliseconds.

1.9. Resolution The module has a resolution of approximately 0.1 C, 0.1 F or exactly .01 millivolts. The chart below shows the corresponding input resolution per step for each of the input configuration modes: CTI 2559-TC Installation and Operation Guide...
Avoid placing low voltage wire parallel to high-energy wire (if the two wires must meet, cross them at a right angle) • Avoid bending the wire into sharp angles • Use wireways for wire routing • Avoid placing wires on any vibrating surface CTI 2559-TC Installation and Operation Guide...
The 505 front panel connector supplied with the 2559-TC is a modified connector with temperature sensors built in. Do not attempt to use a standard connector, as the thermocouple measurements will not be recognized and an error code will be reported on all channels. CTI 2559-TC Installation and Operation Guide...
The information is reported via DIP switches SW1 and SW2 (see Figure 2.2). Each output channel uses 3 switches with a BCD code to indicate the state of the hardware jumpers. The following chart illustrates the BCD which is needed to achieve the desired thermocouple type. CTI 2559-TC Installation and Operation Guide...

14-gauge wire. The actual size used depends on the thermocouple wire providing the input signal. To assign an input to a specific channel, locate the appropriate channel position on the screw terminal connector as shown in the following figure: CTI 2559-TC Installation and Operation Guide...
If either of the two temperature sensors fail, an error code of 32,761 will be reported to the PLC and the modified connector needs replacing. In the unlikely event this occurs, contact CTI for replacement connector part number ‘2559-FPC’ for your replacement front panel connector. CTI 2559-TC Installation and Operation Guide...

Figure 2.8 Input Connector Assembly 2.7. Calibration of the Module Unlike its Siemens® counterpart, the CTI 2559-TC needs no calibration of inputs or cold junction compensation. NOTE: The 2559-TC Thermocouple Input Module is calibrated at the factory. No further calibration is required.
If a module failure is reported by the status word, the module should be replaced with a working unit and the failed module sent in for repair. NOTE: It may take 15-30 minutes after initial installation for temperature readings to stabilize. CTI 2559-TC Installation and Operation Guide...
(see section 2.5.1.) Figure 3.1 Troubleshooting Matrix CAUTION: The module fuse F1 is not user serviceable. If this fuse is blown, the module has a serious component failure and should be returned to CTI for repair. CTI 2559-TC Installation and Operation Guide...

The CTI 2559-TC should fulfill all the following requirements for the 505-7028-A replacement, as outlined below: Module setup The CTI 2559-TC sets up the same as its Siemen’s counterpart, without any input or CJC calibration needed. See Chapter 2.3 Configuring the Module for Operation to determine the details in module setup.
The 2559-TC Thermocouple Input Module is calibrated at the factory. No further calibration is required. All calibration parameters are stored in non-volatile memory. There are no user adjustments on this product. As shipped there is no jumper required on the CAL input. CTI 2559-TC Installation and Operation Guide...
