YOKOGAWA YHC5150X-01 | FieldMate HART Handheld Communicator | In Stock

Description

Key Technical Specifications

Product Introduction

The YHC5150X-01 is the tool you grab when a transmitter is reading wrong, a valve positioner is drifting, or maintenance needs a loop check before the next startup. It is Yokogawa’s FieldMate handheld HART communicator, built to sit on the 4–20 mA loop and talk directly to smart field devices. No laptop, no PRM host, no waiting for IT to approve a USB port. You clip it in, poll the device, and start working.What makes this unit useful in the field is the DD Direct capability. Instead of relying on a limited command set, it reads the manufacturer’s device description file and presents the actual device parameters. That matters when you are dealing with non-Yokogawa transmitters, older positioners, or mixed-vendor instrument lists. The 1 GHz processor and color touchscreen keep navigation faster than the old BT200-style menus, and the QWERTY keyboard still beats a touchscreen when you are wearing gloves. This specific revision carries intrinsically safe certification for Zone 0 / Division 1 use, but only when the correct battery pack and memory card are installed. I have seen units fail safety audits because someone swapped in a generic SD card. Do not do that.

Quality SOP & Tech Pitfalls

The Lab Report (SOP)

1. Visual and Counterfeit Check: Inspect housing, screen, keypad, battery compartment, and certification label. Verify “YHC5150X-01” and intrinsic safety markings.
2. Battery and Charger Check: Test battery charge cycle and cradle indicator behavior. Confirm the battery pack matches Yokogawa specifications.
3. Power-On and OS Check: Verify the unit boots cleanly, touchscreen responds, and keypad registers all keys.
4. HART Communication Test: Connect to a known HART device or test loop. Confirm polling, device ID readback, and basic parameter access.
5. DD Direct Function Check: Load a device description file and verify device-specific parameters appear correctly.
6. Micro SD Card Verification: Test card recognition using a Yokogawa-approved memory card. Non-approved cards may void intrinsic safety certification.
7. Firmware and Asset Logging: Record firmware version, serial number, and installed DD library revision.
8. ESD and Protective Packaging: Anti-static bag, foam insert, rigid carton. Test report available on request.

The Engineer’s Warning (Pitfalls)Two mistakes that cause real headaches:

• Using a non-Yokogawa Micro SD card in a hazardous area. The certification label is explicit about approved memory cards. A generic card may work fine on the bench, but it can invalidate the intrinsic safety approval. In an audit or incident review, that is not a small detail.
• Assuming DD Direct means “works with everything automatically”. The communicator still needs the correct device description file. If the DD library is outdated, you may see generic HART parameters but miss device-specific diagnostics. Update the DD files from Yokogawa or the device manufacturer before a major turnaround.

Installation & Configuration Guide

30-Minute Field Setup

1. Pre-Installation ⚠️
   • Confirm the area classification and your work permit. This unit is intrinsically safe only when properly configured.
   • Inspect the battery pack, label, and certification plate.
   • Charge the unit fully before first use.
   • Verify the Micro SD card is a Yokogawa-approved part if used in hazardous locations.
2. Battery and Card Installation
   • Install the battery pack using the specified screws. Do not overtighten.
   • Insert the approved Micro SD card if device descriptions need to be loaded.
   • Power on and confirm normal boot.
3. HART Connection
   • Connect the communicator across the HART loop or across the 250 Ω resistor as required.
   • Verify the loop has sufficient voltage for HART communication.
   • Poll the device and confirm tag, descriptor, and device ID readback.
4. Device Configuration and Testing
   • Load the correct DD file if needed.
   • Perform zero trim, range check, or output test only when process conditions allow.
   • Save the device configuration report if required by maintenance procedure.
   • Document serial number, firmware version, and device changes in the maintenance log.

Frequently Asked Questions (FAQ)

Q: Can I use the YHC5150X-01 in a hazardous area?
Yes, but only when the unit carries the correct intrinsic safety label, uses the approved battery pack, and follows the Yokogawa installation drawing. The charging cradle must stay in a safe area.Q: Does it work with non-Yokogawa HART devices?
Yes. It supports HART 6/7 and uses DD Direct to read manufacturer device descriptions. You still need the correct DD file for full device-specific access.Q: Can I use any Micro SD card?
No. Yokogawa specifies approved memory cards for this communicator. Using an unapproved card can void the intrinsic safety certification.Q: Is this the same as the BT200?
No. The BT200 is an older Yokogawa handheld communicator. The YHC5150X-01 is a newer FieldMate HART communicator with a color touchscreen, QWERTY keyboard, and DD Direct support.Q: Can I update the firmware and DD files?
Yes. Firmware and device descriptions can be updated through Yokogawa FieldMate tools or approved update procedures. Check the current revision before a turnaround.Q: What warranty do you offer?
Standard 12-month warranty on tested units. New surplus may carry remaining OEM warranty where applicable. A functional test report can be provided on request.Q: What should I check if it powers up but cannot poll a device?
Check loop voltage, wiring polarity, the 250 Ω resistor requirement, HART address settings, and whether the device is in multidrop mode. Also verify the communicator firmware and DD library are current. Most “no communication” issues come from the loop, not the communicator.
