The TIO-3000 System was originally designed to perform precision summing on 2, 3, or 4 load cell signals for weighing applications. Development has progressed into accessory modules with considerable versatility for user defined configurations in a compact economical five (5) slot system with built-in meter and channel selector. Please see below for more information on the four available plug in modules and for available system configurations.
The TMO-3 Module provides sensor excitation, zero balance control, gain adjustment and calibration resistor, necessary to condition one (1) strain gage type sensor signal for display on built-in meter, off board recording or processing. The nominal output range of the module is 0 to ±10 VDC. The TMO-3 module derives its power from the TIO-3000 motherboard. On-board regulators supply amplifier bias and bridge excitation. Each module contains a two-pole filter as the final element.
The PKD-3 Module provides very fast response to variations in data level and captures the highest peak that occurs in a given monitor window. Unlike microprocessor controlled meters that covert in digital readings at three samples per second and then save the highest reading, the PKD-3 tracks continually and holds in analog form until reset. The module has polarity select and reset control which can be operated from the front edge of the module or remotely by switching TTL control lines to ground.
A typical application for the PKD-3 is with a TMO-3 and a torque transducer and used with an automatic nut runner. When the runner stalls, peak torque is saved. If backoff torque is needed for system evaluation, the module can be rest to zero and the polarity changed, both by computer.
The DSP-3 is designed as a watchdog module to monitor critical sensor data from a TMO-3 or SUM-3 Module. The window is normally associated with signals such as: below norma (yellow), go range or acceptable (green), and above acceptable (red). Front edge LED's provide this status, as do output relays. The window is set by a high and low potentiometer, with set values displayed on the TIO-3000 meter, usually in a engineering unit like the sensor channel it is tracking. Output relays can be used to drive larger external alarm devices or to switch off the process or activity that is causing the unacceptable level.
The SUM-3 Module is designed for precise weighing application by accepting the output signals from 2, 3 or 4 TMO-3 conditioning modules and performing the algebraic sum of those signals. Unlike resistor summers, the active element summing junction does not require sensor signals of matching output. The TIO-3000 approach provides a cal resistor to scale amplifiers (TMO-3s) to engineering units. With data now standard during setup, precision summing is accomplished.
