8-Channel Modbus I/O Module - MAS-AI-U-8-M Masibus is a low-cost 8-Channel Modbus based remote IO unit in DIN rail mounting, which provides an easy way for integrating analog signals to supervisory SCADA/PLC/DAS systems. There are several inputs which this model accepts as an input like mA, V, RTD, Thermocouple, etc. Modbus IO module measures all field signals with accuracy of 0.1% of FS. Modbus IO module has high speed scanning rate of 125msec/Channel. This module is powered by 24VDC auxiliary supply and power consumption is limited to 3Watt maximum. This module provides isolation between channel to channel and between all input signals and power thus protecting the connected instrument by eliminating ground loop effects. This reduces substantially the undesirable interferences and instabilities in measurements from sensor. Modbus IO can be easily configured, calibrated and diagnosed via the digital interface by using the Windows based Masibus ‘mAIM’ free software. It automatically detects active devices in the Modbus network and permits configuration of all parameters. Modbus IO configuration is done via the RS485 interface by using Modbus-RTU commands. Features: Accepts mA, V, RTD, T/C Programmable 8-Channels, 16-bit resolution 1.5KV Isolation between supply/input/output Dual serial Modbus communication port 24VDC Auxiliary power supply Programming and calibration using software DIN rail mounting Cost effective as Distributed IO
