Item 01 - Wide-bandwidth single-channel signal conditioning modules that amplify, protect, filter and isolate analog input voltages. Provide a 10 kHz bandwidth which ideally suits them to measuring signals that vary rapidly with time. Protect the computer side from damage due to field-side over-voltage faults. All models withstand 240V rms at their input terminals without damage thereby shielding computer-side circuitry from field-side over-voltage conditions. In addition, modules are mix-and-match and hot swappable, so can be inserted or removed from any socket in the same backplane without disrupting system power. A chopper-stabilized input amplifier provides low drift and stable gain. At the amplifier input, a stable, laser-trimmed zero scale input offset is subtracted from the input signal to set the zero-scale value. A single-pole anti-aliasing filter resides at each modules input. A three-pole, low-pass filter in the output stage sets the bandwidth and yields optimal noise performance for accurate measurement of small signals in high electrical noise. Signal isolation by transformer coupling uses a proprietary modulation technique for linear, stable and reliable performance. The differential input circuit on the field side is fully floating, eliminating the need for any input grounding. A demodulator on the computer side of the signal transformer recovers the original signal, which is then filtered and buffered to provide a low-noise, low-impedance output signal. The output common must be kept within 3Vdc of power common. Isolated Analog Input Voltages of -10 V to +10 V . Amplifies, Protects, and Filters Analog Input. 10kHz bandwidth which ideally suits them to measuring signals that vary rapidly with time. Generates an output of -5V to +5V. Module circuitry can withstand 240v rms Compatible with Item 03 Item 02 Single-channel signal conditioning modules that amplify, protect, filter and isolate analog input voltages. Protect the computer side from damage due to field-side over voltage faults. All models withstand 240V rms at their input terminals without damage thereby shielding computer side circuitry from field-side over voltage conditions. In addition, modules are mix-and-match and hot swappable, so can be inserted or removed from any socket in the same backplane without disrupting system power. A chopper-stabilized input amplifier provides low drift and stable gain. At the amplifier input, a stable, laser-trimmed zero scale input voltage is subtracted from the input signal to set the zero scale value. Internal multi-pole low-pass filtering with a four-Hz cutoff (-3dB) enhances normal-mode (noise on signal) and common mode (nosie on signal return) rejection at 50/60 Hz, enabling accurate measurement of small signals in high electrical noise. Signal isolation by transformer coupling uses a proprietary modulation technique for linear, stable and reliable performance. The differential input circuit on the field side is fully floating, eliminating the need for any input grounding. A demodulator on the computer side of the signal transformer recovers the original signal, which is then filtered and buffered to provide a low-noise, low-impedance output signal. The output common must be kept within +3 V of power common. Isolated Voltage Input of -10 V to +10 V . Amplifies, Protects, Filters, & Isolates Analog Input Voltages. Generates an output of -5V to +5V. Multi-pole low-pass filtering with a four-Hz cutoff Module circuitry can withstand 240v rms Compatible with Item 03 Item 03 16 channel backplane that provides single-ended, high level analog input/output pins on the system connector. Signal connections between the backplane and the associated measurement and control system are made at P1 and P2. These connectors are identical electrically. The redundant connectors may be useful if it is used for both analog input and analog output and the data acquisition system has separate input and output connectors. A signal path is provided for each channel and, in addition, a number of grounding pins are present in the connector pin-out to provide inter-channel shield conductors in the ribbon cable. In some cases, discussed below, the ground conductors will not provide an accurate signal reference, so a SENSE pin is also provided in the pin-out. Several jumper and component options on the backplane provide optimum ground connections for various circumstances. The backplane is factory configured with Jumpers W1, W3, and W4 installed. Jumper W1 grounds the shield wires in the ribbon cable (Pins 3, 6, 12, 15, 18, 21, and 24) at the 5B01 backplane. This will usually be the primary ground connection between the backplane and the measurement system. This connection is required if output modules will be used on the backplane. It is also required is there is no high impedance sense input (input Low of a differential or pseudo-differential system) available on the measurement system. Jumper W4 connects +5VDC power common to input/output common (backplane measurement ground). A connection between power common and input/output common is important for the modules to function properly, however, if this connection is made elsewhere in your system the best place is usually near the A/D or D/A converters), W4 should be cut, since a ground loop could result. The backplane gives the user the capability of directing the voltage output of any input module to an adjacent output module simply by placing a jumper between the pins of the two modules (input to channel n, output from channel n+1). This feature can be used to provide an isolated current output from an isolated input module, giving two levels of 1500 V rms isolation.
