Specifications

Description

IS200TDBSH2A IS200TDBSH2AAA is a contact input terminal board developed by GE. It is a part of the Mark Vle control system. The board serves as a simplex contact input/output terminal board, facilitating easy integration into various systems. The board is engineered to accommodate a maximum current rating of 5 A and provides ample voltage clearance suitable for 250 V AC across all customer screw and JW1 circuits. It's worth noting that the relay rating serves as the determining factor for each specific application.

Applications

Power Generation: Status monitoring of gas turbine and steam turbine power plants (such as GE Frame series units) and power grid distribution systems.

Energy and Utilities: Protecting circuits in power generation and distribution systems to ensure stable operation and secure power supply.

Communications and Data Centers: Monitoring the operational status of critical equipment such as servers, routers, and switches in the distribution cabinets of communication base stations and data centers.

Petrochemicals and Mining: Handling complex discrete logic switching signals in large oil refineries or mining facilities with their own power plants.

Contact Inputs

1 Functionality and Signal Conditioning: The contact input functionality and on-board signal conditioning mirror those of the board. However, they are specifically scaled to accommodate wetting voltages of 24, 48, and 125 V DC. The input wetting voltage range varies accordingly: 16 to 32 V DC, 32 to 64 V DC, and 100 to 145 V DC, respectively. The threshold voltage for contact sensing is set at 50% of the wetting voltage.

2 Current Limitation and Protection: Contact input currents are effectively managed to ensure operational safety and reliability. The first 21 circuits are resistance-limited to 2.5 mA, while circuits 22 through 24 can handle currents up to 10 mA. Additionally, the 24 V DC supply on the TDBSH2 terminal is safeguarded by polymer positive temperature coefficient fuses, which limit the current to 0.5 A. These fuses are resettable, enhancing the board's protection against overcurrent situations.

3 Noise Suppression and Surge Protection: Each input is equipped with filters that effectively mitigate high-frequency noise and suppress surge near the point of signal entry. This ensures that the signals remain clean and stable, even in challenging industrial environments with high levels of electromagnetic interference (EMI) and transient events.

4 Signal Processing and Transfer: The discrete input voltage signals are routed to the I/O processor, where they pass through optical isolators for isolation purposes. Subsequently, the signals are converted to digital format and transferred to the controller for further processing and action.

Features

1 Flexible Mounting Options: Designed with installation convenience in mind. It supports both DIN-rail mounting and flat mounting, allowing engineers and technicians to select the most practical configuration based on available panel space and system design requirements. This flexibility ensures adaptability in diverse control cabinet layouts.

2 High-Capacity Contact Inputs: Supports 24 group-isolated contact inputs. Compatible with nominal wetting voltages of 24 V DC, 48 V DC, or 125 V DC supplied from an external power source. Each input is integrated with noise suppression circuitry, which protects the system from electrical surges, transient spikes, and high-frequency interference. This ensures stable, accurate signal detection even in environments prone to electrical noise.

3 Versatile Relay Outputs: Provides 12 Form-C relay outputs, enabling efficient switching and control of connected devices and processes. Designed to accommodate optional relay output expansion cards, allowing customization to meet specific operational needs. These relays offer the reliability and endurance required for continuous industrial operation, making the board suitable for mission-critical applications.

Frequently Asked Questions

Q: What is IS200TDBSH2A IS200TDBSH2AAA?

A: IS200TDBSH2A IS200TDBSH2AAA is a contact input terminal board developed by GE as part of the Mark VIe series. It serves as an interface for connecting field contact signals to the Mark VIe system.

Q: What configuration options are available for the IS200TDBSH2A IS200TDBSH2AAA?

A: The terminal board itself does not include any jumpers or hardware settings for configuration. Any necessary adjustments are made through associated option boards or software settings.

Q: How does the WROBH1 option board handle relay power distribution of IS200TDBSH2A IS200TDBSH2AAA?

A: WROBH1 includes six jumpers that control whether power is applied to each relay. Removing a jumper allows the corresponding relay to function solely as a dry contact without distributing power.

Q: What is the configuration process for option board WROFH1 of IS200TDBSH2A IS200TDBSH2AAA?

A: WROFH1 does not have jumpers. Configuration is determined by the terminal point designated as the relay common. Removing the associated WROF fuse allows the relay’s voltage sensing circuit to be used directly as a voltage detector.

Q: How does option board WROGH1 handle relay fuses of IS200TDBSH2A IS200TDBSH2AAA?

A: Similar to WROFH1, WROGH1 does not have jumpers. Users can remove each relay’s corresponding fuse if the relay is intended to operate as a dry contact without power distribution.

Q: Are there any hardware adjustments required for the WROFH1 and WROGH1 boards of IS200TDBSH2A IS200TDBSH2AAA?

A: No hardware adjustments are required. Users can configure relay fuses or dry contact operation without using jumpers.
