Digital Input/Output Module (DIO) 04G5940 (DIO module)

This module contains the interface electronics for the RMP and PEP, and can also be used to monitor or control a variety of external devices. It provides eight fully protected digital input lines, eight digital output lines with sufficient power to drive small motors, two relays and access to the counting and timing functions of the Base Unit. The module input/output signals may be accessed using the cable adapter, or plugging a PSL Prototype card directly into the rear of the module. The DIO module is fully supported by a comprehensive technical reference to help you or your students develop custom accessories and programs.

Eight protected outputs, eight protected inputs, and two relays (Form C)
Four pulse width modulators
Pulse counting and timing on all inputs
Supports up to two Rotary Motion Probes (RMP)
Supports up to two chains of four Photo Event Probes (PEP) each
The prototype card can be used to create unique output connections

David Ress got his DIO module, and he got the front off. His last words were "My God, it's full of stars"... Actually, he said "Clips overlapping on the front of the module".

DIO Jack Adapter 04G5942 (DIO module)

This adapter provides two modular jacks to interface the DIO module to the RMP, PEP and other digital accessories that use a modular plug.

DIO Cable Adapter 04G5941 (DIO module)

Use this DIO adapter to connect the Digital Input/Output Module to a variety of switches, relays, motors, robots or other devices in your laboratory. The Cable Adapter connects to the rear of the DIO module and provides full access to the interface signals of the DIO via a 34-conductor flat ribbon cable. The one meter cable is terminated with a 2 row by 17 position connector designed to mate with a standard 0.100 inch spacing pin header. The DIO Technical Reference gives complete details of the signals available.

Rotary Motion Probe (RMP) 04G5944 (DIO module)

This patented, PSL unique probe is a true motion microscope. It measures angular position with a resolution of 0.25 degrees (that's 1440 counts per revolution!) and linear position to 0.1 mm. This probe is simple to use and requires no calibration, yet can reveal relationships never before seen in the classroom. When used with the optional accessory kit, the RMP can perform many of the linear and angular experiments common in the physics classroom. Also has applications in physiology and biology for muscle deflection, etc.

Rotary Motion Accessory Kit 04G5945 (DIO module)

Two inner masses, two outer ring masses, a pendulum rod, an RMP shaft adapter, a thumbscrew, a spool of “special” (non-elastic) thread, and two springs, allow the RMP to perform a great variety of experiments. The RMP User Guide gives typical applications for the physics classroom.

Rotary Motion Probe Kit PSL7510 (DIO module)

Includes the Rotary Motion Probe and RMP Accessory Kit.

Photo Event Probe (PEP) 04G5948 (DIO module)

A photogate so unique we had to give it a new name. With a rise time of less than two microseconds, this probe is truly faster than a speeding bullet, and we measured the speed of a bullet with this probe to prove it. The PEP uses a visible red LED light source and is fully configurable for photo-timing of objects as small as a thread or as large as a softball. When used with the Laser Source, it can time objects larger than a bus. The mounting system also allows the PEP to be used as a reflective sensor, enabling many new applications.

Laser Source 04G5951 (DIO module)

A 1 milliwatt visible ( 670 nm red) class II laser for stand-alone laser experiments or use in conjunction with the Photo Event Probe. The Laser Source can be used in place of the LED Source in a PEP to greatly extend the range of separation between the Source and Receiver. The Laser Source comes with a 4 meter cable for use with the PEP or may be connected directly to the Digital Input / Output Module Jack Adapter.

Precision Picket Fence PSL7134 (DIO module)

The PSL Precision Picket Fence is designed for use with the PSL Photo Event Probe (PEP) to provide students an easy and accurate method to measure the free-fall acceleration due to gravity. Machined slots in a Lexan™ base ensures high accuracy and immunity to damage from handling and storage. The fence can also be attached to moving objects such as cars to measure their velocity using the PEP.
