POSITION INDICATORS

Digital Position Indicators

Programmable Digital Position Indicator T-735

• For use in positioning applications with Screw Jack screw jacks and actuators.
• Displays position of lifting screws in increments of 0.01 mm or 0.001”.
• Brilliant 18.5 mm high Dual colour display. Red or Green user defined e.g. Green normal operation and Red position limit reached.
• User-Friendly interface programmable from front panel via four rubber keys with help function on secondary 7 mm high display.
• Non-volatile memory retains all programmed information and count value in the event of power loss.
• Two adjustable up/down output limits (pre-sets), with a 0 +/-99999 range, can act as limit switches.
• Five digit input scaling 0.0001 9.9999, programmable decimal point location and lead zero blanking.
• Display convertible to metric, imperial or other units of measurement.
• For position indication on actuator applications Screw Jack recommend feedback from a shaft encoder for precise, reliable and maintenance-free operation.
• Programmable front panel functions may be locked out to prevent unauthorised adjustment.
• Reset capability allows reset to zero from front panel.

Inputs

• Count inputs - 2 channels A and B ideal for encoder connection. Capable of TTL, 30V DC max. at 10 kHz.
• Digital inputs - 2 terminals (NPN) can be used to activate pre-configured functionality e.g. remote reset and security mode.

Outputs

• 2 NPN outputs activated each pre-set. Two red LED’s on panel indicate activation.
• 2 Relay outputs (Normally Closed or Open) activated each pre-set.

The position indicator can be furnished as a complete screw jack or actuator positioning kit which includes digital position indicator, incremental shaft encoder with flying lead or connector and cable (variable cable length available), actuator coupling and worm shaft adapter (for installing the encoder) and mounting bracket. Electrical connections are made at the rear to the unit to terminal strips.
