Linear Displacement Transducer (LDT) Interface PLC Module For Allen-Bradley ControlLogix

Product Features:

  • Two-channel LDT interface
  • Direct interface to most sensors that output PWM, control pulse, or start/stop signals
  • Onboard diagnostics monitor and report errors
  • Latch inputs for capturing the position data value
  • PLC time can be sent to the module to generate an interpolated (look ahead) data value
  • Incorporates Rockwell Automation licensed technology for 100% compatibility with 1756 PLC

AMCI 7252 Linear Displacement Transducer (LDT) Interface PLC Modules for Allen-Bradley ControlLogix

allen-bradley encompass partner

AMCI Model: #7252

Bringing LDT position sensor data into the ControlLogix PLC has never been easier! AMCI's (2) channel 7252 LDT interface card can directly interface to two magnetostrictive sensors with PWM, control pulse, or start/stop signals.

AMCI's LDT Interface Card is a magnetostrictive linear displacement transducer (LDT) based module that incorporates Allen-Bradley licensed technology for guaranteed compatibility with A-B Series 1756 I/O chassis. Plus, it's a direct interface to today's most popular LDT sensors, including Balluff, Ametek, Gemco, MTS, and Turck.

AMCI's 7252 card monitors machine position and delivers continuous absolute position data to the ControlLogix processor down to 0.001" or 0.10mm resolution. The module also returns velocity data, based on the position scaling in counts per second, and transducer diagnostics. System Integrators and PLC programmers will value the module's simplicity and flexible performance. If required, the module can use the coordinated system time (CST) to generate an interpolated position data value for high speed applications, and latch inputs are available for capturing the position data value.

Customers working in markets such as Forestry and Wastewater control will appreciate the module's latch inputs. Whereas customers configuring machinery for Injection Molding, Slitting, and Hydraulic Cylinder control will value the module's simplicity and flexible performance.

AMCI's 7252 interface module is a cost effective approach to system upgrades, enabling you to specify a ControlLogix PLC without obsoleting your LDT sensors.
