Yokogawa TA50-2N 40-Point Terminal Block Unit

Yokogawa TA50-2N: 40-Point M3 Connector Terminal Block

Product Introduction

This connector terminal block unit converts 40-pin ribbon cable signals into screw terminals for control panels. Engineers select the TA50-2N when cabinet space is tight but M3 screw clamping is still required. Specifically, the 6 mm terminal pitch packs 40 points into a short rail span. Its gray housing also separates it visually from other terminal blocks in the same enclosure.

Technical Specifications

The TA50-2N carries a rated voltage of 5-24V DC and an operating range of 4.5-26.4V DC. Each point supports a maximum current of 0.5A DC. Moreover, the unit accepts conductor sizes up to 1.25 mm² maximum. Terminal block screws are M3 type, and the terminal arrangement pitch measures 6 mm. Additionally, the connector is the HIF3BA-40PA-2.54DSA (71) type, which complies with the MIL standard. Two M4 clamping screws secure the block, and the unit weighs 162 g.

Compatibility Note

The connector terminal block cannot be used with the F3YP04, F3YP08, F3YP14, F3YP18, F3YP22, F3YP24, F3YP28, F3NC32, and F3NC34 modules. Therefore, confirm your module model before ordering. For instance, users of those nine modules should choose a different Yokogawa wiring accessory.

Installation Guide

First, pick 35-mm DIN rail or direct screw mounting for the TA50-2N. Next, fasten the block with the two M4 clamping screws and confirm it sits firmly. Then, plug the 40-pin HIF3BA connector from the I/O module into the block header. After that, strip field wires and attach solderless terminals up to ø5.8 mm. Tighten each M3 screw snugly, but avoid excess torque. Finally, check continuity point by point before applying power.

FAQ

Q1: Which modules are incompatible with the TA50-2N?
A1: The TA50-2N cannot be used with the F3YP04, F3YP08, F3YP14, F3YP18, F3YP22, F3YP24, F3YP28, F3NC32, or F3NC34. Verify your module model before purchase to avoid wiring mismatches.

Q2: What conductor size does this terminal block accept?
A2: The unit accepts conductors up to 1.25 mm² maximum. Additionally, it takes solderless terminals up to ø5.8 mm, which covers most panel wiring needs.

Q3: How does the TA50-2N differ from the TA50-1N?
A3: Both units use M3 screws and accept 1.25 mm² wire. However, the TA50-2N has a tighter 6 mm pitch and weighs 162 g, while the TA50-1N uses a 7 mm pitch and weighs 175 g.

Q4: What connector type does the unit use?
A4: The block uses the HIF3BA-40PA-2.54DSA (71) connector, which complies with the MIL standard. This 40-pin header mates with standard FA-M3 ribbon cables.

Q5: Can I mount the TA50-2N on a DIN rail?
A5: Yes. The unit mounts on 35-mm wide DIN rail or by direct screw fixing. Two M4 clamping screws hold the block securely in either arrangement.
