I/O modules

Product Overview

The GE DS200DTBCG1AAA serves as a dedicated contact output termination module within the Mark V control system. This board provides the physical interface between the control logic and external field devices. It translates digital commands into dry contact switching actions. Industrial facilities rely on this module for actuator and solenoid control.

Technical Specifications

The DS200DTBCG1AAA measures 254 mm in length and 88.9 mm in width. This compact module fits standard Mark V rack slots. The board weighs approximately 0.4 kilograms. It requires a +5V DC supply with a maximum current consumption of 0.8 A.

Output Channel Architecture

This module integrates sixteen independent relay-based output channels on a single board. Each channel uses a high-quality electromechanical relay for reliable switching performance. The relays handle 2 A at 30 VDC or 0.5 A at 125 VAC. Every channel includes a flyback diode for inductive load protection. This diode suppresses voltage spikes from solenoid and relay coils. The board provides 1500 VAC isolation between channels. This isolation prevents cross-talk and protects the control circuitry.

Connectivity and Diagnostics

The GE DS200DTBCG1AAA features two 37-pin D-sub connectors for field wiring. One connector handles the output terminals while the other carries the return lines. Sixteen bright LED indicators show the real-time status of each output channel. These LEDs simplify troubleshooting and system validation. The board incorporates a 22 μF filter capacitor for stable power delivery. This capacitor smooths out voltage fluctuations from the backplane supply.

Installation and Integration

Installing the DS200DTBCG1AAA requires a single slot in the Mark V drive cabinet. The board connects directly to the VME backplane via its edge connector. It receives command signals from the main processor card. Field wiring terminates at the D-sub connectors using standard ribbon cables. The module operates reliably across a 0°C to 60°C temperature range. Its compact design allows dense system configurations. Proper shielding minimizes electromagnetic interference in high-noise environments.

Reliability and Service Life

The DS200DTBCG1AAA uses industrial-grade relays rated for 100,000 operations minimum. This rating ensures long service life in continuous duty cycles. The flyback diodes extend relay contact life by reducing arcing. Routine maintenance involves visual inspection of status LEDs and terminal connections. Replacing the module requires no special tools or complex procedures.
