Keyboard Programming
The MINI-PLS is fully front panel programmable with convenient tactile keyboard and yet secure against any unauthorized program changes. Opening of an external user provided keyswitch inhibits any program changes on the front panel.

RUGGED AND RELIABLE

Single or Multi-turn Resolver or Ultrasonic Linear Transducer Input 
The MINI-PLS combines the ruggedness of a brushless resolver or noncontacting ultrasonic linear transducer and the reliability of an advanced solid-state control. The rugged, heavy-duty NEMA 13 (IP54) single- or multi-turn resolver can be mounted on a machine in any hostile environment; such as mechanical shock, vibrations, extreme humidity and temperature changes, oil mists, coolants, solvents etc. The programmable control unit can be mounted up to 2500 feet (1000 feet for linear transducer) away in a control panel. The splash-proof oil-tight front plate permits the unit to be installed directly on the machine itself, if so required. The ratiometric converter assures high tracking speed of 1800 rpm and high noise immunity.

Modular, Easy to Service
Modular 40 Channels in 6.25" x 4.5" x 7.25" compact enclosure. The ultra-modern technology used by Autotech has made it possible to house 40 channels in such a small space saving enclosure. The system flexibility is further enhanced by the modular construction. The unit can be expanded up to 40 channels using five modules of eight channels each. A cam module with desired logic level or power outputs or a separate chassis with plug-in power relay outputs can be selected to match the application. Parallel BCD position and tach output modules can be inserted in slots 4 or 5. This modular concept also permits an easy adoption in field to the future technological developments by simply adding new modules to the same basic unit.

EEROM TRANSPORTABLE MODULES

No Batteries, Nonvolatile EEROM Memory
The scale factor, offset, dwell, and motion detector setpoints are all stored in nonvolatile EEROM memory as they are entered by the user. The information is retained indefinitely after power loss or machine shutdown, eliminating need for back-up batteries and related hazards.

Program Stored in Transportable Plug-in Modules 
The program setpoints are stored directly in the cam modules in nonvolatile EEROM memory. The information is retained without power, even when the modules are taken away from the MINI-PLS. This unique feature of program storage in the cam module permits programming of various modules for different jobs or spares, reducing downtime and eliminating eventual errors due to hurried reprogramming at job changes. Also, the cam modules can be programmed at a central place, such as corporate headquarters, and distributed to various plant locations.

Variety of Plug-in Output Modules
The plug-in cam modules are optically isolated and are available with TTL, PNP or NPN type of logic level outputs. The sub D connector style on these modules with preassembled cable assembly eliminates all field wiring and the related eventual wiring errors. Power cam modules are also available with AC (120 VAC @ I A) or DC (10-28 VDC @ I A) ratings. Optional electromechanical relays (10 A) and solid-state AC (3 A) or DC (3 A) relays are mounted on a separate chassis. All these relays are plug-in type for easy field replacement. The solid-state relays are optically isolated. Optional parallel BCD position and tach output modules with built-in PC-handshake as well as analog position/tach output modules are available for remote readouts or control devices.
