PIL 50-110 Series PCI Relay Board SPDT

The PIL 50-110 Series PCI Relay Board SPDT is the latest generation of PCI general-purpose reed relay switching cards introduced by Pickering Interfaces, and is part of the 50-110B/50-115B product family.This series offers two contact configurations: SPDT (Single-Pole Double-Throw/Change over) and SPST (Single-Pole Single-Throw/Normally Open). Each card can accommodate 32 or 64 relay channels, with signal input via a 200-pin female LFH connector on the front panel.

The PIL 50-110 series is a mature product that has evolved over time on Pickering’s PCI platform, having undergone three generations of iteration: 50-110 → 50-110A → 50-110B. While maintaining core electrical performance, each generation has featured continuous upgrades in firmware compatibility, diagnostic tool support, warranty coverage, and operating system support.

The Key Characteristic- PIL 50-110 Series PCI Relay Board SPDT

Pickering’s general-purpose reed relay cards for PCI platforms have evolved through three generations.

The 50-110B series is positioned as the flagship product line for general-purpose reed relay switching on the Pickering PCI platform, complementing the following products:

• 50-120B/125B (shielded versions): Add electromagnetic shielding to the 50-110B design, suitable for applications with higher bandwidth and crosstalk performance requirements.
• 50-131A/50-132 (2A Relay Cards): Based on electromechanical relays, these are suitable for medium-power (2A/60W) switching applications.
• 50-510A/511A/512A/513A (Matrix Cards): Featuring dedicated matrix topologies (22×4, 44×4, etc.), these are suitable for large-scale crosspoint switching.

Switch Topology Funtions- PIL 50-110 Series

Signal Routing Functionality

• SPDT Model (50-110B): Each channel includes a common terminal (C) and two output terminals (A/B). In the default state, the C-B path is closed (normally closed); when the relay is energized, it switches to the C-A path being closed (normally open). Supports switching between two signal paths.
• SPST Model (50-115B): Each channel includes a common terminal (C) and one output terminal (A). In the default state, the circuit is open; when the relay is energized, the C-A path becomes conductive. Suitable for building simple signal switching matrices.

Programming Control

• All relays are centrally managed by a single sub-unit
• SPDT/SPST models: Controlled via bits; each bit corresponds to one relay
• Supports single-channel operation (OpBit) and batch mode operation (WriteSub/setChannelPattern)
• The Relay Lookup Table maps logical channel numbers to the physical relay locations on the PCB, facilitating fault diagnosis

Diagnostics and Maintenance

• eBIRST Diagnostics: Connect the eBIRST tool via the USB port to automatically scan all relay paths and detect abnormalities such as soldering defects, open circuits, and contact resistance issues.
• BIRST Built-in Self-Test: Built into matrix-type products, allowing diagnostics to be run without external devices.
• Test Panels Graphical Interface: After installing the driver, you can intuitively operate all relays through the graphical panel.
• PILMon Command-Line Tool: Provides a complete command-line interface; enter “HE” to view help.
• Diagnostic Report Tool: Generates PCI configuration diagnostic reports to assist in troubleshooting installation issues.

Installation Precautions

• The card contains electrostatic-sensitive components; before handling, discharge static electricity by touching the antistatic bag to a metal part of the chassis.
• Perform installation with the system powered off but still grounded.
• The host chassis must be properly connected to the utility power supply and the facility’s safety ground.
• Do not use in safety-critical circuits.
• Do not use for utility power circuit switching.
• The signal source and the device under test must be completely isolated from the utility power supply.

Customization Services

• Multi-channel signal distribution in functional testing

FAQs:

Q: In Windows Device Manager, the card is displayed as 'PCI Device' with a yellow exclamation mark, or as 'Pickering Switch Card' but cannot be controlled. What should I do?

A:  

If it displays 'PCI Device' with an exclamation mark, it means the driver is not correctly bound. You can right-click and update the driver in Device Manager, select 'Manually Specify Path' and point it to the installed Pickering official driver.

If it displays 'Pickering Switch Card', it means the currently installed .inf driver file version is lower than the production batch of the hardware and cannot achieve software mapping. It is recommended to uninstall the existing Pickering driver software and download the latest version from the official website for installation.

Q: How can I resolve the issue of not being able to find the board in NI MAX (Measurement & Automation Explorer) software or being unable to access it via NI-VISA?

A: 

Pickering boards support two low-level driver modes: Direct I/O and VISA driver.

If you need to control via NI-VISA or LabVIEW, you must ensure that you download and install the Pickering Pipx40 NI-VISA driver.

In NI MAX, go to Tools -> NI-VISA -> VISA Options, then to General Settings, and check "Show all devices accessible to VISA". After rescanning, it will be correctly mounted to the NI automation system.

Q: How much voltage and current can the 50-110 series boards switch? Can it be connected to 220V mains power?

A: 

Do not connect directly to mains power.

The maximum rated switching voltage for the 50-110 (and 50-110A) is 150 VDC / 100 VAC, the maximum switching power is 3W or 20W (depending on the specific sub-model), and the maximum switching current is generally between 0.25A and 1.25A.

The official specifications clearly state that to achieve the full rated operating voltage, the test signal source must be completely isolated from the mains supply and safety earth. Directly introducing mains power or a large inductive load will generate a high-voltage transient arc, instantly breaking down and melting the reed contacts.
