Modbus RTU/ASCII Master/Slave Communication Module

PTQ-MCM

Limited Availability: Product with low inventory remaining. More Info

The PTQ Modbus Master/Slave Communication Module allows Schneider Electric Quantum processors to interface easily with other Modbus protocol-compatible devices.The PTQ Modbus module provides an easy way for users of the Schneider Electric Quantum processor to add two Modbus serial ports to the control platform.

The module acts as an Options module for the Quantum platform allowing communication on a Modbus serial network. Compatible devices include not only Modicon® PLCs (almost all support the Modbus protocol) but also a wide range of process and control devices from a variety of manufacturers. Many SCADA packages also support the Modbus protocol.
