• Supply Voltage: +5V DC, +15V DC, -15V DC (provided by the Mark IV rack backplane)
• Power Consumption: Low-power design (specific value depends on the number of active channels)
• Operating Temperature Range: 0°C to +60°C (32°F to 140°F) (industry standard, specific versions may have a wider range)
• Storage Temperature Range: -40°C to +85°C (-40°F to 185°F)
• Protection Rating: Designed for installation in control cabinets (IP20 or similar)
• Weight: Approximately 0.35 kg
• Installation Method: Vertically inserted into a dedicated Mark IV system rack/cage, connected via a backplane connector
• Communication Interface: Communicates with the main controller through the Mark IV backplane bus

Structure and Composition

• Front Connector/Terminal Block: Provides physical connection points for field sensor cables, usually using screw terminals or pluggable terminal blocks for easy wiring and maintenance. Each channel corresponds to an independent terminal.
• Multiplexer (MUX): Sequentially switches analog signals from multiple channels to the subsequent common processing circuit, reducing costs and minimizing volume.
• Analog-to-Digital Converter (ADC): A core component that converts the conditioned analog voltage signals into digital values processable by the control system. The IC3600ALTC uses a high-precision, high-resolution ADC chip.
• Isolation Circuit: Uses optocoupler isolators or transformer isolation technology to provide electrical isolation between input channels, between input channels and the module’s internal logic circuits, eliminating ground loop interference and improving noise immunity and safety.
• Logic Control Circuit: Contains a microcontroller or programmable logic device (PLD) responsible for controlling the multiplexer switching timing, ADC start and read operations, data temporary storage, and data exchange with the Mark IV main controller through the backplane interface.
• Status Indicators (LEDs): Usually located on the front of the module, providing visual indicators for power, channel status, faults, etc.
• Backplane Interface Connector: Gold fingers or high-density connectors used to insert the module into the Mark IV rack, obtain operating power, and communicate with the system backplane bus.
