GENERAL DESCRIPTION
The SIO-MB04RTDS device is a Modbus TCP server that can convert up to 4 analog signals applied to the inputs into engineering units in digital format.
The inputs can be connected to two-wire or three-wire RTD or resistance sensors.
The input channels are electrically isolated from each other.
The device guarantees high accuracy and a stable measurement versus time and temperature. The device is equipped with a selectable Watchdog Timer
system. The Ethernet interface allows reading and writing the values of the internal registers of the device in real time.
Signal LEDs for Ethernet activity and power supply allow direct monitoring of the system.
The built-in Web Server allows remote visualization, acquisition of the analog inputs and access to the configuration parameters.
Connections are made by removable screw terminals (inputs and power supply) and RJ45 plug (Ethernet).
The SIO-MB04RTDS is in compliance with Directive UL 61010-1 for the US market and with Directive CSA C22.2 No 61010-1 for the Canadian market.
The device has full electrical isolation between the lines, providing protection against the effects of ground loops existing in industrial applications.
It is housed in a tough self-extinguishing plastic enclosure which, thanks to its thin 22.5 mm profile, allows high-density mounting on EN-50022 standard DIN rail.
USER INSTRUCTIONS
Before installing the device, please read the “Installation Instructions” section.
To configure the device in INIT mode, refer to the User Guide. Connect power supply, Ethernet and analog inputs as shown in the “Wiring” section. The LED
states indicate the working condition of the device; see the “Front Panel LEDs” table to verify the device working state.
Instructions for configuration and calibration operations are contained in the User Guide.
To simplify handling or replacing of the device, it is possible to remove the wired terminals even with the device powered.
