Resolver Based PLS - 1995A Micro-Set PLS

Resolver-based PLS,  Micro-set Programmable Limit Switch - The Series 1995A PLS was designed for use in rotary application.  It incorporates many features for safe, efficient operation.  The completely self-contained unit can operate up to 30 independent outputs (six standard) based on the rotary position of the resolver.  It offers an on-line "fault check" that provide an automatic, in process mechanism to verify that all major programmable limit switch functions are operating properly, The "fault check" output can be energized by activating the fault-check enable input.  The output is a mechanical relay that is energized during normal operation, having 1 N.O. and 1 N.C. contact. 

This unit can be used with our Series 1986 Resolver Assembly.  Enclosure options include Nema 4 and Nema 12.

Resolver Based PLS - 1995B Micro-Set PLS with Brake Monitor

Micro-set Programmable Limit Switch with Brake Monitor - The Series 1995B Micro-Set PLS was designed for use in the mechanical press industry.   It incorporates many features for safe, efficient press automation.  This completely self-contained unit can turn up to 30 independent outputs on or off based on the rotary position of the press crank.  On-line brake monitoring checks the stopping time of the press against a customer-selected preset stopping time.  It can also be used to check the stopping distance at any point in the stroke.  A dedicated mechanical SPDT relay remains energized when stopping time is within tolerance.  Once exceeded, the mechanical relay de-energizes to initiate a stoppage or warning signal.

This unit can be used with our Series 1986 Resolver Assembly.  Enclosure options include Nema 4 and Nema 12.

1991 Manual

Resolver Based PLS - 1991 Quik-Set IV UHS PLS

Quik-Set IV UHS Programmable Limit Switch -  The Series 1991 PLS is an ultra high-speed programmable limit switch designed to provide set point control in high-speed machine applications.  Its hardware driven logic circuits operate at a throughput time of 10 microseconds (.00001 seconds) on the first 16 output circuits.  This allows one count accuracy on systems with 3600 counts per revolution scale factor at speeds over 1600 RPM.  Speed compensation software allows independent rates of advance or retard on the leading and trailing edge of a programmed set point.  This allows full compensation for both the on and off response time of the machine function being manipulated for precise control of its location and duration within the machine cycle.  Operation programming can be done through its keypad or remotely via RS232 or RS485 from a PLC, PC or any computer device with two-way serial communications capability.      

The PLS system's position information, programs and set pint memory are non-volatile, making it as realizable as fixed limit or proximity switches, but far more flexible.

Resolver Based PLS - 2500 High Speed PLS

High Speed Programmable Limit Switch - The Series 2500 PLS is a high-speed resolver based Programmable Limit Switch that monitors rotary machine position and provides discrete limit switch outputs. These outputs are updated at a much faster rate than can be accomplished using any conventional PLC.  The 2500 PLS uses a unique easy to understand programming sequence. The traditional number buttons have been replaced with a rotary knob and the main controller has a 2 x 24 vacuum fluorescent display along with four push-button keys for programming.

The Series 2500 is a family of PLS's that offers unparalleled flexibility. The main controller is resolver-based and consists of 8 isolated DC inputs and 8 isolated output relays, one fault check output relay and one optional brake monitor input relay.
