I/O modules

Product Overview

This terminal contact board serves as a critical interface between field wiring and the Mark VIe control system. It organizes discrete input and output connections for turbine and generator applications. The IS200TBACIH1B provides a centralized termination point for multiple I/O signal types. Its compact design simplifies cable management within crowded cabinet environments. This board ensures reliable signal transmission from field devices to the controller.

Technical Specifications

The IS200TBACIH1B measures 22.9 cm in width and 17.8 cm in depth with a standard mounting height. It weighs approximately 0.45 kg, including all terminal blocks and mounting hardware. This board operates from a 24 VDC power supply with a maximum current draw of 200 mA. It features 24 discrete terminal points for connecting field wiring to the system. Each terminal accepts wire sizes from 0.5 mm² to 2.5 mm² (20 to 14 AWG). The board includes built-in surge suppression components for each channel. It also provides LED indicators for power status and channel activity monitoring.

Signal Interface and Connectivity

This terminal board interfaces with the Mark VIe controller through a 50-pin ribbon cable connector. It accepts both digital inputs and relay output signals from field devices. The IS200TBACIH1B supports sinking and sourcing configurations for flexible system design. Each terminal position includes a clearly labeled number for simplified wiring identification. The board also incorporates test points for troubleshooting individual signal paths.

Physical and Electrical Parameters

Installation and Wiring Guidelines

Mount the IS200TBACIH1B securely on a standard 35 mm DIN rail inside the control cabinet. Connect the 50-pin ribbon cable to the corresponding controller interface port. Terminate each field device wire to its designated terminal position with proper torque. Verify all connections before applying power to avoid potential damage. The board provides clear labeling for each terminal to assist with installation and maintenance. Regular inspection ensures reliable long-term operation.

Typical Applications

This terminal board finds extensive use in gas and steam turbine control systems. It manages signals from pressure transmitters, temperature sensors, and valve position feedback. The IS200TBACIH1B also serves in generator excitation and protection applications. Its robust design suits harsh industrial environments requiring high reliability.
