BEFORE REPLACEMENT

Checks That Prevent Installation Delays

Confirm NAMUR compatibility

ASD143 is specified for IEC 60947-5-6 NAMUR inputs. Do not select it solely because the installed card or sensor is described as digital input.

Check the signal timing

Fast or narrow pulses may fall outside the limits. Compare the application with the 15 ms response, 20 ms minimum ON time and 25 Hz maximum cycle.

Preserve polarity and channel order

Each of the 16 inputs has a positive and negative terminal. Record every INx+/INx− connection before removing the terminal assembly.

Match single or redundant hardware

Use ATSB4S-0 with one ASD143 or ATSB4D-0 with two adjacent redundant modules. Check the suffix, terminal and slot arrangement together.

PRODUCT DETAILS

Product Image Display

Reference photo shows ASD143-P00. Confirm pulse-count suffix, NAMUR field devices and ATSB4 terminal hardware before ordering.

Verify ASD143-P00

Read the full front label before ordering. The P00 suffix identifies the NAMUR input version with pulse-count capability.

Preserve input polarity

Map IN1+/IN1− through IN16+/IN16− before disconnecting the ATSB4 terminal so channel order and polarity are not reversed.

Confirm the timing requirement

Compare the sensor pulses with the 15 ms response, 20 ms minimum ON detection and 25 Hz maximum ON/OFF cycle.

TECHNICAL ANSWERS

Frequently Asked Questions

What exactly is Yokogawa ASD143?

Yokogawa ASD143 is a 16-channel digital input module with a built-in barrier. Its input interface is specified as NAMUR compatible to IEC 60947-5-6.

Is Yokogawa ASD143 a general-purpose 24 V DC input module?

The Yokogawa specification identifies ASD143 as a NAMUR IEC 60947-5-6 input module; it does not specify a general 24 V DC contact-input card. Check the field sensor against the NAMUR interface requirement.

Are the 16 Yokogawa ASD143 channels individually isolated?

No. The built-in barrier provides galvanic isolation between the field interface and the system, but Yokogawa states that these modules do not provide isolation between channels.

What is the status-input response time of Yokogawa ASD143?

The specified status-input response time is 15 ms.

What pulse timing can Yokogawa ASD143 detect?

For pushbutton input, the minimum detectable ON time is 20 ms. The maximum specified ON/OFF cycle is 25 Hz.

Does Yokogawa ASD143 include pulse counting?

Yes. The orderable module suffix is ASD143-P00, where P is identified as with pulse count.

Which terminal blocks connect to Yokogawa ASD143?

ATSB4S-0 is the 16-point single pressure-clamp terminal. ATSB4D-0 is the 16-point dual-redundant terminal for two adjacent ASD143 modules.

What are the Yokogawa ASD143 current consumption and dimensions?

Maximum consumption is 150 mA at 5 V DC and 110 mA at 24 V DC. Module weight is approximately 0.30 kg, and the outline drawing shows 32.8 × 130 × 107.5 mm.

ABOUT PLCEXPORT

Technical Verification, Inventory Control and Order Fulfillment

PLCEXPORT checks the complete ASD143 model and suffix, terminal option, visible condition and quantity before dispatch planning. This helps prevent a similar-looking FIO module or incompatible pressure-clamp terminal from reaching the job site.

Organized inventory control

Warehouse locations and package labels are checked against the requested model before dispatch planning.

Sales and technical coordination

Model codes, terminal requirements, quantity and delivery details are reviewed in one workflow.

Order follow-through

Our team follows the order from sourcing and confirmation through shipment updates and after-sales coordination.

PLCEXPORT pre-dispatch component inspection

Pre-dispatch product check

Visible condition, product labels and packing details are reviewed before the component enters the export process.
