Features

• 4-Channel input configuration for multi-point monitoring.
• Supports high-speed pulse counting up to 50 kHz.
• Optimized for turbine flow meter signal processing.
• Input impedance of 25 kOhms for signal integrity.
• Compact SLC 500 form factor for efficient rack space utilization.

Technical Specifications

Installation Guidelines

• Ensure the SLC 500 chassis is powered down before inserting or removing the module to prevent electrical damage.
• Verify that the module is fully seated in the backplane slot and secured with the provided mounting screws.
• Use shielded twisted-pair cabling for flow meter inputs to minimize electromagnetic interference (EMI) in high-noise industrial environments.
• Maintain proper grounding practices for the chassis to ensure signal stability and operator safety.
• Avoid routing signal cables in parallel with high-voltage power lines.
