I/O modules

The DS200CTBAG1A DS200CTBAG1ADD offers reliable field wiring termination for Mark V systems. This board connects field devices directly to the main controller’s I/O channels. It simplifies cabinet wiring and speeds up maintenance work.

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 all terminal blocks. DS200CTBAG1A DS200CTBAG1ADD weighs exactly 1.2 kg for stable mounting. You will find 40 screw terminals arranged in two parallel rows of twenty.

Furthermore, the board includes 12 passive RC filtering components near each terminal pair. These components suppress high-frequency noise from incoming field signals. A continuous ground plane runs through the four-layer PCB for signal integrity.

Connector Interfaces and Signal Routing

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

Mechanical Design and Mounting

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

Typical Application Scenarios

You can deploy DS200CTBAG1A DS200CTBAG1ADD in gas turbine control panels for field wiring termination. It also works well for steam turbine protection systems and generator exciters. This board terminates analog inputs, digital outputs, and thermocouple signals efficiently. Its high 15A current rating supports power distribution to field devices.
