Limitorque Master Communication Interface Module

3100-LTQ

The ProSoft 3100-LTQ Master Module allows the user to easily implement a redundant loop network or a multidrop network with up to 150 Limitorque valve actuators.

The 3100-LTQ (Limitorque Valve Actuator Master Module) product family allows Allen-Bradley 1771 compatible processors to easily interface as a host with Limitorque valve actuators. The module supports the Limitorque redundant loop network mode (up to 150 actuators) of communications as well as a single multidrop network (up to 28 actuators). The 3100-LTQ (PLC) Limitorque Valve Actuator Master Modules is a single slot solution, which communicates directly over the backplane with the respective Allen-Bradley processors.

Features

Simple to Use
All module setup and write command initiation is performed over the backplane through simple ladder logic and data table configuration. Any standard ladder programming software can be used.

Hands Off Operation
Once the LTQ module has been setup for operation, all active valve actuators will automatically be polled for status data. This data is returned to the ladder data table for monitoring and control purposes. The LTQ module is integrated directly into the PLC rack, forming a tightly integrated and practical solution.

Installation, Set Up and Operation
The ProSoft module installs in any slot in a local or extended rack (or a remote rack in the case of the 3100 module). The product's capabilities are enabled and controlled with simple ladder logic and data table initialization.
