Product Description

Magtrol’s SBB15 Signal Breakout Box is designed to assist in the monitoring of speed, torque, and index signals obtained from either a Magtrol dynamometer or torque transducer. The easy-to-use SBB15 is simply inserted in series between a Magtrol controller and any Magtrol dynamometer or torque transducer. Connections are made via D-Sub 15 signal cables.

Speed, torque, and index signals are outputted through BNC connectors to an oscilloscope or other DAQ instrumentation device. Switching to the external encoder will switch the Tach A, Tach B, and Index signals, while the Torque signal will still be passed through from the dynamometer or torque transducer. The SBB15 Signal Breakout Box is a convenient and reliable accessory that reduces the necessary wiring required for signal monitoring.

Features

  • Two D-Sub 15 Connectors: provides an in-line connection between a Magtrol DSP Controller and a dynamometer or a torque transducer
  • Four BNC Connectors: provides easy access to Tach A, Tach B, Torque, and Index signals for connecting to an oscilloscope or other data acquisition (DAQ) device
  • Sturdy Assembly: packaged in an extruded aluminum case with metal mounting flanges
  • An external encoder input is provided for connecting high resolution encoders
  • A slide switch allows switching between a torque transducer and an external encoder

                    [post_content] => Magtrol offers these calibration beam assemblies and weights for calibrating HD-Series Hysteresis Dynamometers. To perform a successful dynamometer calibration, precision weights heavy enough to apply a torque at or close to the full scale rating are required. Magtrol WT Series Calibration Weights are equal to the dynamometer's torque value, divided by the distance between the outer pin and centerline of the corresponding CB Series Calibration Beam. Calibration Weights are available in English or SI units. Calibration Beams are marked for both English and SI weights. For detailed dimension drawings, click on the model's underlined link.

All eight thermocouples pairs are bundled into a single cable and terminated in a die cast aluminum box with barrier strip jackets for easy connection.

Interconnection errors can be avoided by using the barrier strip with the relevant thermocouple extension or compensation material. The strips are marked to identify the alloy and polarity.

The box can be supplied with optional T-nuts for easy mounting to a T-slot table or Magtrol PT 25 Base Plate.

                    [post_content] => DES 410 Series Power Supplies are specially designed for the full range of Magtrol’s Eddy-current and Powder brake dynamometers with the design goal providing the best response time. The DES 410 Series supplies are packaged in an industrial housing made of cast aluminum. This offers superior protection against radiated emissions in order to avoid any disruption of the surrounding electronics modules. This housing must be installed directly on the test bench, next to the brake, as close as possible.

The DES 410 Series supplies can be controlled by digital signals and analog set point coming from peripheral electronics. The DSP7010 Dynamometer Controller has been designed to work with the DES 410 Series.

Control

The Power supply can be switched ON by remote control. The STAND-BY signal enables the output current to be delivered. This excitation current is controlled by a set-point in the 0-10 V DC range. The nominal value of the excitation current is set by internal resistors. There are two discrete outputs for alarms (open collector). The first is the "Temperature Alarm". It will indicate if the cooling water of the Dynamometer or the inner temperature of the DES 410 Series are out of limits. The second is the "Electrical Alarm". It occurs when an over current or a short circuit is detected. The output current is immediately turned OFF and latched while the General Alarm Relay is set under its Alarm position. A low state for 200 ms of the Stand-by signal resets the latch.

For applications with TANDEM dynanometers, the DES 410 Series units also control the power supply of the electromagnetic clutch.

Supply Voltage

The main supply voltage of the DES 410 Series is in the 115/230 VAC - 50/60 Hz range. No selection is required.

The DES 410 power supply features a galvanic insulation between the main circuit and the dynamometer power.

The DES 411 does not have galvanic separation. For safety reasons, the DES 410 Series case has to be grounded and the use of a ground fault current circuit breaker is recommended.
