This module provides eight isolated current output channels, specifically engineered for precision control in industrial automation environments. It is designed to interface seamlessly with the Mark VIe architecture, ensuring reliable signal transmission for field devices requiring 4-20 mA current loops.

Features

• Eight independent current output channels.
• Supports 4-20 mA output range with high precision.
• 16-bit resolution for fine-tuned control applications.
• Robust common mode rejection (CMR) of > 120 dB at 50/60 Hz to minimize electrical noise interference.
• Low heat dissipation, rated at 2.5W maximum.
• High dielectric strength of 1500V AC for 1 minute for enhanced safety and isolation.

Technical Specifications

Installation Guidelines

• Ensure the control system is powered down before inserting or removing the module from the rack.
• Verify that the module is correctly seated in the designated Mark VIe I/O slot to ensure proper backplane communication.
• Use shielded twisted-pair cabling for all analog output connections to maintain signal integrity and reduce EMI.
• Maintain proper ventilation in the control cabinet to stay within the specified operating temperature range of -30 degC to 65 degC.
• Ensure all field wiring is properly terminated and secured to prevent intermittent connections.
