Description
The Seneca Z-DAQ is designed to accept a single channel analogue input which can then be incorporated to a SCADA system or other ModBus RTU compatible supervisory system thanks to the Z-DAQ's 2 Wire RS485 ModBus RTU connectivity. The Seneca Z-DAQ is characterised by the vast number of possible analogue input types it can be used with.
