Input Specifications

• The module provides 8 non-isolated universal input points.
• Each input point can be configured as either sinking or sourcing for maximum wiring flexibility.
• The on-state input voltage range is 9.6V DC min, 24V DC nom, to 28.8V DC max.
• Maximum off-state voltage is 5.0V DC for clear signal distinction.
• On-state current is a low 8 mA max per point at 28.8V DC.
• The nominal input impedance is 4.8 kΩ.
• Eight green status LEDs provide individual input channel feedback.
• The input common type is configured as 8 points per common (8 COM) in a non-polarity design.

Output Specifications

• The module provides 8 non-isolated sinking output points.
• The on-state output voltage range is 10V DC min, 24V DC nom, to 28.8V DC max.
• Maximum on-state voltage drop is only 0.5V DC for efficient power delivery.
• Minimum on-state current is 1 mA per channel.
• Maximum off-state leakage current is a low 0.5 mA.
• Output signal delay is fast: 0.5 ms max Off to On, 1.0 ms max On to Off.
• Eight dedicated green status LEDs indicate the state of each output.
• The output current rating is 0.5A max per output, with a 4.0A max per common.
• The output common type is also 8 points per common (8 COM).

General Specifications & Power

• Part of the Allen-Bradley CompactBlock LDX series of expansion modules.
• DeviceNet power for the base block is 24V DC nominal (11…28.8V DC range).
• Maximum power dissipation from DeviceNet power is 1.2 W at 28.8V DC.
• Field power for I/O is 24V DC nominal (10…28.8V DC range).
• Field power dissipation is approximately 6 mA per point at 28.8V DC.
• It features photocoupler isolation (1250V AC RMS) between I/O and logic for safety.
• DeviceNet to logic and DeviceNet power connections are non-isolated.
• Wiring uses a terminal block (M3.0) with a max screw torque of 7 lb-in.
• It includes a built-in DeviceNet communication port for network connectivity.
• Designed for screw mounting and operation up to 2000 meters above sea level.
• It is lightweight, weighing only 0.06 lbs (0.03 kg).
