I/O modules

The DS200CLACG1A DS200CLACG1AAA functions as a logic control board for Mark V systems. This board processes digital input signals and drives relay output channels. It handles critical sequencing tasks in turbine control applications.

Key Technical Specifications

Physical Dimensions and Component Layout

This board measures 6.5 cm in length and 14.5 cm in width. Its total height reaches 2.0 cm including all components. DS200CLACG1A DS200CLACG1AAA weighs exactly 1.1 kg for secure installation. You will find 188 discrete components on a six-layer PCB.

Moreover, the board includes a 1000 µF bulk capacitor for energy storage. This capacitor smoothes voltage dips during simultaneous relay switching events. It also provides a 10 ms hold-up time after supply interruption.

Connector Interfaces and Signal Routing

The front panel provides one 20-pin header for digital input connections. A separate 24-pin header handles all 12 relay output channels. Two 4-pin auxiliary connectors supply 24V power and ground references. Furthermore, twelve LED indicators show the real-time status of each relay.

Relay Output Characteristics

Each relay offers Form C (SPDT) contacts for flexible wiring configurations. The common terminal, normally open, and normally closed contacts are all accessible. These relays switch 250V AC or 30V DC loads up to 5A. Consequently, you can directly control contactors, solenoids, and indicator lamps.

Typical Application Scenarios

You can deploy DS200CLACG1A DS200CLACG1AAA in gas turbine start-up sequencing panels. It also works well for steam turbine protection logic and valve control. This board reads limit switches, pressure switches, and pushbutton inputs. Its 12 relay outputs drive annunciators, alarms, and actuator signals.
