PIL 50-125 Series Shielded Relay Card SPST

This PIL 50-125 Series Shielded Relay Card SPST is a functionally equivalent shielded version of the unshielded 50-115 series, designed for automated test applications requiring 50MHz bandwidth signal switching, high isolation, and low crosstalk.

The 50-125 series utilizes Pickering Electronics' highest quality instrument-grade reed relays, equipped with sputtered ruthenium contacts, offering excellent performance in low-level and small-signal switching scenarios. The complete mu-metal magnetic shielding enclosure effectively reduces inter-relay magnetic crosstalk from 40% to just 1%, ensuring signal integrity even in high-density installations.

Attention: The 50-125 series has been replaced by Pickering's updated 50-115B series (50-125-021 → 50-115B-021, 50-125-121 → 50-115B-121). The new 50-115B series has been optimized and upgraded while maintaining full pin compatibility and functional equivalence.

FAQs:

Q: What are the advantages of the 50-125 series compared to the regular 50-110/50-115 series?

A:  

The 50-125 is a shielded reed relay board. The standard 50-110 series is prone to magnetic or capacitive coupling between channels during high-frequency or multi-channel simultaneous switching. The 50-125, through its physical shielding structure, significantly improves signal bandwidth and reduces crosstalk between channels, making it more suitable for high-precision weak signal testing or mid-to-low frequency (hundreds of kHz to several MHz) signal switching.

Q: Which Pickering driver should be used when developing in LabVIEW or C#/C++?

A:  

Pickering employs a general driver architecture. For System 50 (PCI) hardware of the 50-125 series, it primarily provides the following two driver solutions, which can be found in the Pickering driver download center:

Direct I/O Driver (pipx40): This is the lowest-level and most commonly used direct control driver, supporting various Windows development languages ​​and offering extremely fast response times.

IVI-Switch Driver (pi40iv): If your test system architecture requires compliance with IVI instrument standards, this driver can be used to achieve instrument interchangeability.

Q: Why does the error "Resource Name Error" occur when initializing a board in LabVIEW?

A: 

Cause: 50-125 is a PCI card, but many developers directly used the PXI module example, misconfiguring it as a PXI resource format such as PXI::14::INSTR.

Solution: PCI cards are usually identified in the Pickering driver by their card number or bus/slot number. Please open the Pickering Client Bridge (the official hardware management tool) to check the specific Card ID assigned to the PCI card by the system (e.g., Card 1), and pass the correct integer ID or VISA resource name in the initialization function.

Q: How to quickly check if a relay on a 50-125 board is damaged?

A: 

A key feature of Pickering is its support for its self-developed eBIRST testing tool.

Software Diagnostics: By running Pickering's diagnostic software, it closes specific relays via serial commands, guiding the user through the diagnostic channels of external measuring instruments.

Dedicated Fixture: By purchasing the matching eBIRST hardware tool, simply plug it into the 200-pin (or related high-density) interface on the front panel of the board. With a single click, it automatically identifies which relay's contact resistance is exceeding the limit (fully automatic fault detection).

Q: What interface does the 50-125 board use on the front end? How do I connect the cables?

A: 

This series of high-density PCI cards typically uses a 200-pin LFH (Low Force Helix) female connector or a 78-pin D-type connector.

Due to the very dense pin configuration, users are advised against attempting to add additional wiring themselves.

Official cables are provided for the 50-125 series (such as a 200-pin LFH to open-end adapter, or an adapter for four 50-pin D-sub connectors). During system integration, a picking terminal block is usually used for signal wiring to ensure that the shielding effect is not compromised.
