FUNCTIONAL DESCRIPTION:

IS220PTCCH1A REV C 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 Thermocouple Input (PTCC) pack 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. In the Simplex configuration using TBTCH1C, each pack is capable of handling up to 12 thermocouple inputs, for a total of 24 inputs using two packs. In the Simplex configuration using TBTCH1B, each pack is capable of handling up to 12 thermocouple inputs, for a total of 24 inputs provided the packs only use the JRA and JTB connectors. 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. PTCCH2 supports E, J, K, S, and T as well as B, N, and R types of standard thermocouples and mV inputs. The mV span for PTCCH2 is –20 mV to +95 mV.

COMPATIBILITY:

PTCCH1A/PTCCH2A is compatible with the thermocouple input terminal board TBTC, and the STTC board, but not the DIN-rail mounted DTTC board. The following table gives details of the compatibility.

INSTALLATION:

• Securely mount the desired terminal board.
• Directly plug the PTCC I/O pack 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 such that there is no right-angle force 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 remove power from the cable before plugging it in because the I/O pack has the inherent soft-start capability that controls the current inrush on the power application.
• Use the ToolboxST application to configure the I/O pack as necessary.

FREQUENTLY ASKED QUESTIONS:

What is a thermocouple input module?

A thermocouple input module is a device used to measure temperature using thermocouple sensors. It typically converts the small voltage generated by the thermocouple into a digital or analog signal that can be read by a data acquisition system or a control device.

How does a thermocouple input module work?

The module works by connecting to one or more thermocouple sensors. These sensors generate a small voltage proportional to the temperature they are measuring. The module amplifies and conditions this voltage signal to make it suitable for processing by other devices like PLCs (Programmable Logic Controllers) or data loggers.

What types of thermocouples are compatible with these modules?

Thermocouple input modules are typically compatible with various types of thermocouples, such as Type K, Type J, Type T, Type E, etc. Compatibility depends on the module's design and specifications.
