Features :
Optional :
MCS831E-ADX is the latest series of advanced cost effective temperature and process scanners. It incorporates advanced software features and a dual micro controller based design to provide complete user flexibility and can cater to almost all monitoring and data acquisition needs of the user. It can be user programmed to cover different application needs thus reducing time, inventory and spares cost. It has a programmable universal input and accepts direct signals from thermocouples, RTDs and linear voltage and current inputs. Each channel is sequentially scanned and active channels are displayed, Individual channels can be locked for monitoring using the HOLD key. Flexible alarm logic and grouping is provided to energize alarm relay outputs as per the process parameter values and programmed set points.
Serial communication options are provided to enable the scanner to be used in DAS front-end applications. Optional windows based MicroDAS software is also available from 8 to 128 channels for monitoring and data logging using multidrop RS485 option.
