Technical Specifications:

• Channels: 8 isolated channels (4 analog + 4 digital)
• Analog Input: 0–10 V DC or 4–20 mA, 12-bit resolution
• Digital Input: 24 V DC, optically isolated
• Isolation Voltage: 1500 V DC (analog), 500 V DC (digital)
• Supply Voltage: 24 V DC ± 15%
• Power Consumption: Maximum 2 W
• Operating Temperature: -20°C to +60°C
• Protection Rating: IP20
• Dimensions: 90 mm x 70 mm x 45 mm
• Weight: 180 g

Material Composition:

• Housing: Polyamide PA66 GF30, black
• Terminal Blocks: Screw terminals, tin-plated copper alloy
• Isolation Barriers: Optocouplers (Siemens 6N137 or equivalent)

Structural Features:

• Compact DIN rail module
• LED indicators per channel (Power, Signal, Fault)
• Shielded analog input section
• DIN rail clip for secure mounting

Working Principle:
Analog signals pass through a precision resistor network and are buffered by an isolation amplifier (AMC1200 or equivalent). Digital signals are isolated via high-speed optocouplers. All signals are then passed to the backplane bus in a standardized format.

Key Advantages:

• 1500 V DC isolation on analog channels for safety
• Signal buffering prevents loading of field devices
• Mixed analog/digital in compact form factor
• LED channel status for quick diagnostics

Applicable Industries:
Chemical processing, power plants, water treatment, food & beverage, pulp & paper.

Installation Requirements:

• Mount on 35 mm DIN rail (EN 50022)
• Use shielded twisted-pair cable for analog signals
• Ground cable shields at controller end only
• Verify input range (0–10 V or 4–20 mA) matches field device

Usage Precautions:

• Do not apply voltage exceeding 30 V DC to analog inputs
• Ensure 4–20 mA loop power is supplied externally if needed
• Do not mix PNP and NPN sensors on same module
• Maintain ambient temperature within -20°C to +60°C
