Physical Layout and Cabinet Mounting
This terminal board measures 320 mm in width and 200 mm in height. Its depth reaches 40 mm for standard panel mounting. The unit weighs 1.3 kilograms due to the metal frame and dense component layout. Four M5 mounting holes secure the board to a backplate vertically.
Internal Circuitry and Energy Storage
Two hundred four components populate this digital interface board. Five 470 µF capacitors form a 2350 µF total energy storage bank. This bank filters the 24V supply for both input and output circuits. Consequently, the board rejects electrical noise from field cabling effectively. Each input includes an optocoupler for complete bus-to-field isolation.
Input Configuration and Signal Conditioning
Thirty-two digital channels accept 24V DC signals from push buttons and sensors. You can configure each channel as sink or source via on-board jumpers. A 5 ms filter debounces mechanical switch contacts automatically. Green LEDs illuminate when each input channel detects an active signal. Removable terminal blocks accept wires from 0.5 mm² to 2.5 mm² cross-section.
Output Configuration and Protection
Thirty-two digital outputs drive relays, indicator lamps, and small solenoids. Each output channel handles 0.5 amps continuously at 24V DC. Short-circuit protection shuts down an individual output within 50 microseconds. The board automatically resets the channel after removing the fault condition. Red LEDs show the on-off state of each output point clearly.
Control Interface and Compatibility
Three 50-pin ribbon connectors link the board to the Mark V controller. Eight removable 20-pin terminal blocks organize field wiring by function. Both DS200DTBBG1A DS200DTBBG1ABB share identical electrical specifications. The ABB suffix indicates a later revision with improved connector retention. You can use either version interchangeably in any Mark V rack.
