MINI MULTIPLEXER

Lighthouse developed the Mini Multiplexer for monitoring multiple 4-20mA analog points in a single area.

The Mini Multiplexer provides support for up to four 4-20mA input signals (including particle counters) and four external alarm devices, such as light sticks, buzzers or other digital output modules.

The Mini Multiplexer communicates via MODBUS/ASCII or MODBUS/RTU and was designed with two RJ-45 connectors to allow daisy-chaining with other RS-485 instruments. The Mini Multiplexer is compatible with SOLAIRs and other Lighthouse Instruments on a daisy-chain when all are running MODBUS/ ASCII.

Power, Analog Inputs and Digital Outputs are connected via screw terminals for easy field installation and service of the unit. Connection to a variety of sensors and devices is possible without special connectors or tools. The REMOTE Mounting Kit option provides additional flexibility for mounting the Mini Multiplexer.

Designed and built by Lighthouse Worldwide Solutions, a name you can trust.
