Schneider TBXASS200 2 Isolated Analog Output Terminal Base Module

Basic Series Info

• Brand: Schneider Telemecanique (Modicon Premium TSX7 / TBX distributed Fipio I/O series)
• Full definition: Distributed terminal base with 2 galvanically isolated analog output channels
• Bus communication: Fipio fieldbus, matches Premium PLC control system
• Status: Discontinued original production (ceased 2006), spare/refurbished stock available for legacy equipment maintenance

Core Technical Specifications

1. Analog Output Channels
   • 2 fully isolated AO channels, channel-to-channel & bus isolation to suppress industrial interference
   • Standard signal range: 0–10 VDC / 4–20 mA analog control signals
   • High precision analog regulation for process control valves, drives, regulators
2. Hardware & Wiring Structure
   • Integrated removable screw terminal block for field actuator wiring
   • DIP switch address setting (8-bit) to assign Fipio bus node ID (max 31 modules per bus)
   • 9-pin D-SUB connector for Fipio bus cable connection
   • Built-in status LED indicators for power, communication fault, channel abnormal alarm
   • DIN rail cabinet mounting, industrial plastic housing with ground screw terminal
3. Electrical & Environment
   • Operating supply: 24 VDC control power
   • Wide industrial temperature range, EMC compliant for factory workshop, chemical & power plant environments

Key Functions & Advantages

1. Distributed remote analog output collection, extend Premium PLC signal distance via Fipio bus
2. Galvanic isolation eliminates ground loop noise, stable for weak analog control signals
3. Detachable terminal block allows quick module replacement without re-wiring field equipment
4. Local fault diagnosis via front LED, fast troubleshooting of broken wires or actuator faults
5. Compact monobloc all-in-one design (communication board + terminal base + analog output circuit integrated)

Typical Application Scenarios

• Legacy Modicon Premium PLC process control systems
• Petrochemical, water treatment, HVAC temperature/pressure flow regulation
• Control proportional valves, variable frequency drives, analog position regulators
• Old production line, packaging machinery, power plant auxiliary equipment maintenance retrofit
