FUNCTIONAL DESCRIPTION:

IS220PTCCH1A 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 install the desired terminal board.
  • Directly connect the PTCC I/O pack to the terminal board connectors.
  • Mechanically secure the packs to the threaded studs next to the Ethernet ports. The studs slip into a mounting bracket designed for the terminal board type.
  • The bracket location should be changed such that there is no right-angle stress on the DC37 connector between the pack and the terminal board. The adjustment should be required just once during the product's lifetime.
  • Connect one or two Ethernet wires, depending on the system configuration. The pack will work on either port. If twin connections are employed, it is common practice to link ENET1 to the network connected with the R controller.
  • Plug in the connector on the pack's side to power it. It is not essential to turn off the power to the cable before connecting it because the I/O pack has an intrinsic soft-start feature that controls the current inrush on power applications.
  • Use the ToolboxST application to set up the I/O pack as needed.

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 component used in control systems to interface with and measure temperature using thermocouple sensors. It typically converts the small voltage generated by the thermocouple into a usable digital signal for the control system.

Why are thermocouples used in turbine control systems?

Thermocouples are preferred for temperature measurement in turbine control systems due to their durability, wide temperature range capability, and ability to operate reliably in harsh conditions typically found in turbine environments.

How does a thermocouple input module work?

The module connects to one or more thermocouple sensors. It measures the tiny voltage produced by the thermocouple due to the temperature difference between the measurement junction and the reference junction. This voltage is then amplified and converted into a digital signal that can be processed by the control system.
