TA50-2N Yokogawa 40-Channel Interface Block DIN Unit

Interconnection Architecture & Structural Overview

The TA50-2N terminal block adapter bridges high-density I/O cards to field wiring efficiently. Designed by Yokogawa, this TA50-2N interface unit consolidates 40 discrete signal channels through a MIL-standard compliant connector to rugged M3 screw connections.

Mechanical & Electrical Specifications

System Compatibility & Incompatible Modules

• Compatible Systems: Pairs with standard Yokogawa pre-wired ribbon cables and high-density digital I/O cards.
• Incompatibility Notice: Cannot be used with F3YP04, F3YP08, F3YP14, F3YP18, F3YP22, F3YP24, F3YP28, F3NC32, and F3NC34 specialty modules.
• Physical Footprint: Gray molded housing engineered for clean side-by-side DIN rail arrangement inside marshalling cabinets.

Built-in Diagnostic & Protection Features

• Mechanical Security: Dual M4 base clamping screws prevent vibration loosening in heavy industrial machinery.
• Polarity Clarity: Numbered 6 mm pitch terminals eliminate cross-wiring errors during multi-point signal tracing.
• Signal Continuity: Gold-plated ribbon connector pins maintain low-resistance signal paths across high-vibration boundaries.

Global PLC Spare HUB Insight & Field Experience

Our automation engineering team frequently integrates the TA50-2N terminal block when transitioning from flat ribbon cables to heavy-gauge field wiring in tight control enclosures. During a recent chemical plant migration project, technicians utilized this adapter to convert 40-channel controller outputs safely while maintaining isolated 24V DC signal integrity across long cable trays.

Field Engineering Tip: Always verify your target module part number against the exclusion list before ordering, as specialized position modules require dedicated conversion interfaces.

Typical Application Scenarios & Target Machinery

• Control cabinet marshalling panels interfacing PLC racks to field sensors.
• Multi-axis actuator signal distribution hubs in automated assembly lines.
• High-density discrete indicator lamp and push-button console wiring arrays.

Selection & Engineering Buyer's Guide

• Confirm that your total loop current does not exceed the 0.5A per point threshold of the terminal block.
• Ensure your field wiring utilizes compatible solderless crimp terminals under 5.8 mm outer diameter for M3 screws.
• Verify physical cabinet clearance for either 35mm DIN rail or direct M4 screw panel anchoring.

Logistics, Fulfillment & Warranty Protection

• Warranty Terms: Fully backed by a 12-Month Quality Guarantee.
• Fulfillment Speed: Fast dispatch processing within 24 to 48 hours.
• Global Couriers: Secure international shipping via FedEx, UPS, and DHL.
• Package Inventory: 1 x Yokogawa TA50-2N Terminal Block, Mounting Clips, Technical Instruction Sheet.

Frequently Asked Questions (FAQ)

Q: Can I use the TA50-2N terminal block with Yokogawa F3NC32 communication modules?

A: No, the TA50-2N is explicitly incompatible with F3NC32, F3NC34, and specific F3YP series modules due to pinout differences.

Q: What is the maximum wire size supported by the M3 terminal screws?

A: The terminal blocks accept applicable conductor sizes up to 1.25 mm² max. using solderless lugs under 5.8 mm.

Q: Is an external power supply required to power the TA50-2N unit itself?

A: No, this is a passive interface pass-through device; it does not require external power and simply routes incoming field signals.

Q: How do I secure the terminal block to the control cabinet backplate?

A: You can mount it onto a standard 35mm wide DIN rail or secure it directly using the two M4 clamping screws.

Q: What type of ribbon cable connector does the unit feature?

A: It is equipped with a MIL-standard compliant HIF3BA-40PA-2.54DSA (71) 40-pin connector.
