Process Signal Multiplexing
Cable marshalling and milliamp loop connections present significant cost and time during installation. These costs can be reduced through MTL’s Serial I/O to multiplexer by taking 16 digital or 8 digital with 8 analogue connections into a single device and transmitting the data over MODBUS. When interfaced with an MTL wireless network, complete wireless I/O multiplexing systems can be deployed which maximise the opportunities of connections while significantly reducing cabling infrastructure. The I/O data can be transferred to outputs, re-creating the signal in a different location or made available to a SCADA / DCS or PLC though MODBUS protocol.
MTL Process signal multiplexing delivers the following features:
- Three I/O versions with configurable input and output types
- MODBUS or Exception reporting protocol selectable
- RS232 and RS485 ports for standard connection to MODBUS master or into MTL wireless networks
- 0-20mA, 0-10V, pulsed and digital I/O available
- Router operation for connection between two Ethernet networks
- Selectable transmit power to suit application
