This terminal block unit simplifies field wiring for high-density I/O modules in Yokogawa FA-M3 systems. Technicians commonly pair the TA40-0N with 40-pin connector modules to convert ribbon cable signals into screw terminals. Specifically, the unit offers 40 points in a slim black housing that saves panel space. Its compact design suits retrofit work and new cabinet builds alike.
The TA40-0N 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 from 0.08 to 0.26 mm² (AWG23-28). Terminal block screws are M2 slotted head type, while clamping screws are M2.6 cross head type. Additionally, the black housing measures 61.4 x 11.8 x 4.57 mm with the terminal cover fitted. Weight is just 50 g, so it adds minimal load to a DIN rail assembly.
Color: Black
Weight: 50 g
Dimensions: 61.4 x 11.8 x 4.57 mm (with terminal cover)
Operating Temperature: 0 to 55°C
Storage Temperature: -20 to 75°C
Humidity: 10 to 90% RH (non-condensing)
Atmosphere: Free of corrosive gases, flammable gases, and heavy dust
The connector terminal block cannot be used with the F3YP04, F3YP08, F3YP14, F3YP18, F3NC32, and F3NC34 modules. Therefore, verify your module model before ordering. For instance, users of those six modules should select a different wiring accessory from the Yokogawa lineup.
First, mount the TA40-0N on a flat panel or DIN rail near the associated I/O module. Next, connect the 40-pin ribbon cable from the module to the block's header. Then, strip field wires to the correct length and insert them into the screw terminals. Tighten each M2 screw firmly, but avoid overtightening to prevent thread damage. Finally, snap the terminal cover into place and verify continuity with a multimeter before powering the system.

Q1: Which Yokogawa modules work with the TA40-0N?
A1: The TA40-0N suits most 40-pin FA-M3 I/O modules. However, it cannot be used with the F3YP04, F3YP08, F3YP14, F3YP18, F3NC32, or F3NC34. Check your module's connector type before purchase.
Q2: What wire gauge does this terminal block accept?
A2: The unit accepts conductors from 0.08 to 0.26 mm², which corresponds to AWG23 through AWG28. Additionally, each point handles up to 0.5A DC at 5-24V DC.
Q3: What is the difference between the terminal block screw and the clamping screw?
A3: The terminal block screw is an M2 slotted head type for wire clamping. Meanwhile, the M2.6 cross head clamping screw secures the block assembly itself.
Q4: Can I use the TA40-0N outdoors?
A4: No. The unit is rated for indoor operation from 0 to 55°C with 10-90% RH non-condensing. Furthermore, the atmosphere must be free of corrosive gases, flammable gases, and heavy dust.
Q5: Does the package include the terminal cover?
A5: Yes. Each TA40-0N ships with its terminal cover fitted. The cover protects screw terminals from accidental contact and dust during operation.
