Series MSK -
Kepco, Inc.
Kepco's MSK linear power supplies provide a selection of five models, offering 100 Watts of stable benchtop power. They use a high gain linear (series pass) stabilizer circuit for ultra low noise and low ripple output, good stability, and accurate resettability, and they are MIL-STD-461 compliant.MSK's "Preview" switch (d-c on-off) allows voltage and current to be pre-set with the digital meters displaying the set values. At "d-c off," no voltage is applied to the output terminals and no load current needs to be drawn to set the current limit. At "d-c on," the set voltage is applied to the output terminals, the appropriate mode indicator illuminates and the meters indicate actual voltage and current.

Neutronics Manufacturing Co.
Introduction: Measuring the line loop contact resistance by bridges is not the ideal method as the test current is only a few milli amperes. Thus the value is not the true value of the contact resistance. Model HL- 100 is a direct reading tester, and uses a test current of 100A DC, resulting in true v alue and accur ate measurements. Model HL- 100 adopts digital circuit technique and is used for measuring contact resistance of switch control equipments at test current of 100A DC. The measurements are accurate as the test is highly stable.HL- 100 is a new, fully automatic micro controlled tester that measures contact resistance at 100A DC with built in printer. The advantages of HL-100

TYPE HFX-1 -
National RF, Inc
The Type HFX-1 Modulation Monitor is an ancillary piece of equipment, which is used with narrow bandwidth, or older oscilloscopes to allow viewing of RF signals and particularly modulated signals as high as 55MHz. The equipment contains an RF signal source and a broadband mixing circuit which converts the high frequency signal to an intermediate frequency within the oscilloscope’s range. The frequency control dial is simply adjusted until the RF signal is viewed on the scope. BNC connectors are mounted on the rear panel to allow interconnect to the scope and RF probe. This product was previously called "oscilloscope frequency extender" and may be used to view other high frequency signals on older or narrow band scopes.

Type NDB-2 and NDB-3 -
National RF, Inc
National RF’s Type NDB-2 and NDB-3 RF Milliwatt Meters are affordable pieces of test equipment for both the RF laboratory and the home experimenter. Both provide a digital reading of RF power in dB reference 1 milliwatt of power into a 50 ohm load (i.e. 0 dBm). The circuitry consists of a low noise logarithmic amplifier that drives a digital A/D converting meter circuit. The lowest power levels that can be read are about –73 dBm (approximately 40 microvolts or .00000003 milliwatts). The maximum power input should not exceed 10 milliwatts (+10 dBm or .010 watts) when inputed without attenuation. An internal attenuator is provided and described in the next section.

XCBS-DL -
Green Switch Innovations
The XCBS-DL is permanently wired into each crossing warning system, and can be configured with either a removable or non-removable bypass key. Simply connect the track connection harness to the designated track connection terminals. To prevent unnecessary operation of the crossing warning system, insert the key and select "bypass", rotate the knife switch to "bypass" and the crossing is disabled. When in the "bypass" position, a Dummy Track Load is connected to the track wire connections in parallel with the rails and the crossing approaches are shorted, preventing unnecessary activation when track equipment is working in the crossing approach circuit. The opening of one track lead may be desired to prevent unnecessary activation with intermittent shunting on the crossing approaches close to the crossing.

XCBS -
Green Switch Innovations
The XCBS is permanently wired into each crossing warning system, and can be configured with either a removable or non-removable bypass key. Simply connect the crossing control circuits to the designated terminals on the XCBS. The rotating "knife switch" on the left side of the XCBS allows the crossing warning system to be controlled for manual test purposes. To prevent unnecessary operation of the crossing warning system, insert the key and select "bypass", rotate the knife switch to "bypass" and the crossing is disabled. The non-removable bypass key adds an additional level of security for the Bypass function. Optional hookup can be made to the auxiallary terminals to include the activation of a strobe or event recorder input when the XCBS is placed in the "bypass" position.

40-110-121 -
Pickering Interfaces Ltd.
Our 40-110 and 40-115 range of reed relay switching modules are available in both Changeover (SPDT) and Normally Open (SPST & DPST) configurations. Connections are made via a front panel 96 pin male micro-D connector. For applications requiring improved bandwidth and crosstalk performance please look at our 40-120/125 range of shielded reed relay cards. General purpose reed relays are suitable for the construction of small switching networks, for slaving up to larger switches or for operating external devices (e.g. lamps, solenoids etc.). To simplify inter-relay wiring, interconnection points are built onto the circuit board thus easing the construction of complicated wiring.
