The Endevco Model 133 PS/ISOTRON® Signal Conditioner is a three-channel signal conditioner designed for use with piezoelectric accelerometers, ISOTRON® (voltage type) accelerometers, and remote charge converters. It provides an AC output voltage proportional to the charge or AC voltage input and is designed to be powered by 90-240 VAC (with a 9-18 VDC option also available). Up to three Model 133 units can be installed in a 19" rack using the Endevco Model 31979 Rack Mounting Kit.

Function Description:

The Model 133 offers both manual and computer-programmable features. It can be manually programmed from the front panel using a "Select Channel" push-button, "Select Function" push-button, four "EDIT" push-buttons, and a four-character LED display. The unit has two modes of operation: Normal (Monitoring State or No-Monitoring State) and Query/Programming. In Normal mode, the selected state applies to all three channels simultaneously. The unit stores all function settings in its internal memory and restores them automatically at power-up.

Important Technical Specifications:

• Channels: Three-channel piezoelectric/ISOTRON signal conditioner.
• Bandwidth: 200 kHz (-3dB corner).
• Output: 10 Volt Full Scale Output.
• High-Pass Filter: Built-in 10 Hz 4-pole Butterworth High Pass Filter, selectable or bypassable.
• Low-Pass Filter: Plug-in 4-pole low pass filter with a corner frequency settable by an internal header module. Optional filter types and multiple corner frequencies are available, including 300 Hz and 1,650 Hz to meet J211 and ISO6487 requirements. The standard default filter is a 10 kHz Butterworth.
• Fault Indication: Fault indicator for open/short at the ISOTRON input.
• Gain Range: 0 to 1000.
• Power Input: Standard unit: 90 to 264 VAC, 50 to 60 Hz (Universal Input). No jumpers or changes required. Optional "-1" version: +9 to 18 VDC.
• Power Dissipation: 9 Watts typical for both standard and -1 versions.
• Physical Characteristics: Dimensions: 5.57" x 2.52" x 12". Weight: 4 lbs typical. Case Material: Black Aluminum Cover, Medium Gray Plastic Bezel. Current: 1 Amp maximum.
• Serial Interface: RS-232 Serial Interface via an RJ-11 connector on the rear panel.

Usage Features:

• Channel Selection: Users can sequentially select channels one to three for setup and data display on the digital panel meter (DPM).
• Normal Mode:
  • Monitoring State: Takes an RMS reading of the signal at the output of the selected channel every 500 mSec and displays the value on the LED display in Engineering Units (EU) or V out in RMS.
  • No-Monitoring State: Allows for low noise operation by not taking A/D readings and placing the CPU in idle mode, turning the LED display OFF.
• Query/Programming Mode: Activated by pressing the "Select Function" push-button. Allows manual programmability and querying of functions. The current setting for the selected function is displayed on the LED display and can be edited using the four EDIT push-buttons. The unit returns to Normal mode after 20 seconds of inactivity or by pressing "Select Function" while the "Monitoring State" LED is flashing.
• Function Selection: Functions available for programming include Input Select (Piezoelectric or ISOTRON), ISOTRON Current Excitation (0.0, 4.0, or 10.0 mA), Sensor Sensitivity (0.001 to 9999), Output Scaling (0.001 to 9999, limited by gain constraint), High Pass Filter (OFF or 10.0 Hz), Low Pass Filter (OFF or XX.XX kHz), and Monitoring State (EU, V out, or OFF).
• Special Modes: Less frequently used modes, activated by pressing "Select Function" simultaneously with combinations of EDIT push-buttons. These include:
  • Addressing: Programs the unit's address for RS-232 communication.
  • Error List: Retrieves a list of errors causing the "Fault" LED to be ON.
  • Reset: Resets the unit (equivalent to power-up initialization).
  • Store Setup in EEPROM: Forces the unit to store all function settings into non-volatile memory.
  • Test Display: Tests the display board by showing different patterns on LEDs and the LED display.
  • Recall Default Setup: Restores default function settings.
  • Calibration: Allows manual calibration of gain and A/D converter.
• RS-232 Serial Communication: Enables computer control for functions like unit identification, sending/querying settings, sending/querying calibration constants, querying raw/calibrated output RMS data, querying low pass filter corner frequency, querying error list, and resetting the unit.

Maintenance Features:

• Minimal Maintenance: The Model 133 is a self-contained electronic instrument requiring minimal user maintenance.
• No Component-Level Repair: Designed not to require component-level repair by the user. Detailed schematics are available upon request.
• Quality Calibration: The only periodic user-performed function is quality calibration.
• Factory Service: Endevco maintains factory service for repairs or replacements. Users must obtain a Return Material Authorization (RMA) number before returning instruments.
• Packaging: Original or equivalent packaging is recommended for returns to prevent shipping damage.
• Warranty: Endevco warrants new electronic instruments to be free from defects in material and workmanship. Repairs or replacements under warranty are free of charge if the failure is due to defective material or workmanship and the unit is returned within the warranty period.
• Out-of-Warranty Returns: For out-of-warranty repairs, a purchase order authorizing repair/calibration up to $300.00 is required, along with a description of the failure. If repair costs exceed $300.00, Endevco will provide a written quotation.
• Filter Module Installation/Replacement: Involves removing the front panel and cover, prying off the metal grounding shield, and gently removing/installing the filter module(s). Correct orientation is crucial.
• Rack Mounting Kit: Optional kit (PN 31979) to mount one to three Model 133/136 units in a standard 19" rack enclosure. Installation involves removing front panel screws, plastic frame, and then mounting the unit(s) with longer screws provided in the kit.
