Key Features

• Compact 8-channel layout for small analog I/O stations, saves cabinet installation space
• Dual screw terminals simplify field wiring for temperature, pressure, flow transmitters
• Isolated segmented power bus suppresses ground loop interference common in analog measurement circuits
• Keyed 20-pin ribbon cable connector avoids reverse plugging and wiring errors
• Matches all standard Rockwell analog modules (1756 ControlLogix / 1794 FLEX I/O analog cards)
• No built-in fuses, clean layout for low-risk analog signal loops without frequent short-circuit issues
• Uniform wiring standard simplifies on-site commissioning, maintenance and fault troubleshooting

Applications

• Termination of 4–20mA process transmitters (temperature, flow, level, pressure sensors)
• Small-scale process control cabinets, water treatment, food & beverage machinery
• Analog signal collection for valve position feedback, variable frequency drive analog signals
• Distributed remote FLEX I/O stations with limited analog input/output points
