Protective Fail-Safe Circuitry

Those working with explosive devices can have peace of mind with the Alpha 4314’s redundant fail-safe limiting circuitry that physically prohibits accidental ignition in the event of equipment failure.

9 Test Ranges

Select 4 of 9 test ranges when you order, giving you the ultimate in flexibility no matter what your application

4-Wire Kelvin Inputs

Never worry about lead wire length or contact resistance errors requiring redundant calculations with the Alpha 4314’s 4-wire Kelvin inputs.

Portable or AC Power

Option AC-115 replaces the battery functionality with continuous isolated AC power.

US Military-Approved

The Alpha 4314 has been approved by the Department of Defense and all branches of the armed services, including special projects use (i.e. Cruise Missle).

Export Data to PC/Printer/Recorder

You can configure your instrument with a BCD or RS-232 interface which enables the Alpha 4314 to communicate data with other devices.

Designed with Fail-Safe Circuitry

Countless critical military, aerospace, and industrial applications utilize squibs and other blasting agents, and it is vital that these devices detonate precisely when required – not sooner, not later, not while testing for continuity integrity.  To guarantee both the readiness of the device and the safety of the technician or engineer, the Alpha 4314 is equipped with redundant, dual fail-safe, current-limiting network circuitry that ensures instrument test currents cannot exceed the specified amount.

Even in the unlikely event of a worst case component failure, the output current limiting network is still in effect.

To certify that this level of safety is included in your instrument, we simulate a worst-case component failure during final testing and include the resulting recorded output current flow with your order.

Government and Military Approved

The 4314 series’ circuitry has been reviewed and approved by a U.S. Government Safety Board and all branches of our armed forces for specific military programs (i.e. Cruise Missile).

4-Wire Accuracy

The Alpha 4314 KRC utilizes a four-wire Kelvin input configuration to eliminate lead wire length and lead contact resistance errors.

Battery or Isolated AC Power

The units are battery powered with a heavy duty rechargeable NiMH (10Ah) pack for portability and line isolation purposes.  An AC adaptor battery charger is standard.

Automatic Power Control

The Alpha 4314’s internal switching configuration automatically disables the battery charging circuit when in operate mode and removes all power from the output circuitry when in off/charging mode.

EWR Drop-Test Compliant

Compliant To The Eastern And Western Range (Ewr) 127-1 Range Safety Requirements For Drop Test, including that “These devices shall be analyzed to verify that rough handling, dropping, or single component failure will not result in negating the current-limiting feature.”

Options

The options below enhance and expand the capabilities of the Alpha 4314 and can be selected when purchasing.

RS-232 Serial Interface Capability

The interface is isolated to 2.5kV on both power and Data lines and uses iCoupler Technology. Option RS-232 provides a safe way to communicate with the Alpha 4314 via a computer or PLC and allows the transfer of single readings or continuous transmission of data. This interface is for data acquisition only and does not provide range control. See Datasheet for more details.

BCD Capability

For applications requiring data output the Alpha 4314 is available with “BCD.”  Notice that the BCD Option does not interfere or change the FailSafe feature of the instrument.

AC-115 Continuous Isolated AC Power

Replaces battery pack functionality with continuous isolated AC power.
