FUNCTIONAL DESCRIPTION:

IS220PTCCH1B REV F is a Thermocouple Input Module manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. The PTCC provides the electrical interface between one or two I/O Ethernet networks and a thermocouple input terminal board. The pack contains a processor board common to all Mark VIe distributed I/O packs and an acquisition board specific to the thermocouple input function. The pack is capable of handling up to 12 thermocouple inputs. Two packs can handle 24 inputs on TBTCH1C. In the TMR configuration with the TBTCH1B terminal board, three packs are used with three cold junctions, but only 12 thermocouples are available. Input to the pack is through dual RJ45 Ethernet connectors and a three-pin power input. Output is through a DC-37 pin connector that mates directly with the associated terminal board connector. Visual diagnostics are provided through indicator LEDs, and local diagnostic serial communications are possible through an infrared port.

INSTALLATION:

• Securely mount the desired terminal board.
• Directly plug one PTCC I/O pack for simplex or three PTCC I/O packs for TMR into the terminal board connectors.
• Mechanically secure the packs using the threaded studs adjacent to the Ethernet ports. The studs slide into a mounting bracket specific to the terminal board type. The bracket location should be adjusted so that no right-angle force is applied to the DC37 connector between the pack and the terminal board.
• The adjustment should only be required once in the life of the product.
• Plug in one or two Ethernet cables depending on the system configuration. The pack will operate over either port. If dual connections are used, the standard practice is to connect ENET1 to the network associated with the R controller.
• Apply power to the pack by plugging in the connector on the side of the pack. It is not necessary to insert this connector with the power removed from the cable as the I/O pack has inherent soft-start capability that controls the current inrush on the power application.
• Configure the I/O pack as necessary.

OPERATION:

• High-speed processor with RAM and flash memory
• Two fully independent 10/100 Ethernet ports with connectors
• Hardware watchdog timer and reset circuit
• Local ambient temperature sensor
• Infrared serial communications port
• Status-indication LEDs
• Electronic ID and the ability to read IDs on other boards
• Substantial programmable logic supporting the acquisition board
• Input power connector with soft start/current limiter
• Local power supplies, including sequencing and monitoring

FREQUENTLY ASKED QUESTIONS:

What is a thermocouple input module?

A thermocouple input module is a device used to interface thermocouples with data acquisition systems or controllers. It typically converts the small voltage generated by a thermocouple into a usable signal for measurement or control purposes.

How does a thermocouple input module work?

Thermocouple input modules work by utilizing the Seebeck effect, where a voltage is generated at the junction of two dissimilar metals (the thermocouple) when there is a temperature difference between the measurement junction and the reference junction. The input module amplifies and conditions this voltage signal to provide an accurate temperature reading.

What types of thermocouples can a thermocouple input module support?

The types of thermocouples supported depend on the input module's design. Commonly supported types include J, K, T, E, N, R, and S thermocouples. It's important to choose a module compatible with the specific type of thermocouple you intend to use.
