Linear
PLS with Multi-turn (Dual) Resolver
Models SAC-M1450-D64,
SAC-M1450-D128
The multi-turn (dual) resolver MINI-PLS models D64 and D128
resolve the position of a rotary shaft up to 4096 countsper-turn.
These systems, utilizing dual resolvers with built-in precision
gear train, are fully absolute and keep track of the shaft
position as well as number of turns, regardless of power failure,
up to 64 and 128 turns respectively.
Linear
PLS with Ultrasonic Transducer
Model SAC-M1450-LTO
The
linear MlNI-PLS, model LTO, decodes the linear movement with 0.00
1 " resolution and up to 108 " of travel. This unit
utilizes an ultrasonic transducer to monitor the linear position
of a machine by the movement of a 1.3" (33.02 mm) diameter
magnet ring over a 3/8" (9.53 mm) diameter stainless steel
rod. The transducer is connected to an interface box, which is
mounted a few feet away. The linear PLS can be mounted up to 1000
ft (304.8 m) away in a safe control room environment. In addition,
a calibration provision eliminates the need to physically match
the decoder to the rod, a problem encountered in earlier controls.
The
maximum TRUE position ranges up to 108,000 counts but it can be
offset to 524,287. ModZ function for up to two cam modules is
provided. Tach or speed compensation is not available. Instead,
the M1450-LTO provides a direction signal that is on for
increasing position and off for decreasing position.

Choice
of Front-Panel, Back-Panel, or NEMA 12 (IP52) Enclosure Mounting
The basic MINI-PLS unit with its sealed front plate is designed
for front panel mounting. It has T- (5 V, TTL), P-, or N-type (50
V DC @ 100 mA) outputs for light loads or PC interface. For higher
voltages and currents, Power Cam Modules or remote power output
chassis are available. The MINI-PLS can also be purchased in a
back panel mount version with built-in power relay output
chassis. This back panel model can be mounted either inside the
user control panel or in a NEMA 12 (IP52) enclosure available from
AVG Automation.
