I/O modules

The DS200CTBAG1A DS200CTBAG1ACC provides field wiring termination for Mark V control signals. This board connects sensors, actuators, and I/O modules to the main controller. It simplifies installation and maintenance in turbine cabinets.

Key Technical Specifications

Physical Dimensions and Layout

This board measures 30.5 cm in length and 12.7 cm in width. Its total height reaches 2.5 cm including terminal blocks. DS200CTBAG1A DS200CTBAG1ACC weighs exactly 1.2 kg for stable mounting. You will find 40 screw terminals arranged in two parallel rows.

Additionally, the board includes 12 passive filtering components near each terminal. These components reduce electrical noise on incoming field signals. A ground plane runs throughout the four-layer PCB for signal integrity.

Connector Interfaces and Signal Routing

A single 50-pin header connects the terminal board to the main control board. This header carries all 40 signals plus shield grounds and test points. Each terminal has a dedicated identification label for easy wiring. Furthermore, two 4-pin auxiliary connectors provide additional shield termination points.

Mechanical Design and Mounting

Four mounting holes sit at each corner of the board. These holes accept M4 screws for secure attachment to the cabinet backplane. The terminal blocks use a rising cage clamp mechanism for reliable wire retention. A transparent cover protects the PCB from dust and accidental contact.

Typical Application Scenarios

You can deploy DS200CTBAG1A DS200CTBAG1ACC in gas turbine control panels for field wiring. It also works well for steam turbine protection systems and exciters. This board terminates analog inputs, digital outputs, and thermocouple signals. Its high 15A rating supports power distribution to field devices.
