D1 15 – Modbus module with 6-channel 4-20 mA input and 3 PT100
• Analog acquisition module
• 6 inputs 0-10V or 0/4 to 20 ma.
• 3 inputs PT100 2/3
• Serial interface Rs485/422
• Modbus RTU / ASCHI
• Baud rate 9600/19200
• Mounting on DIN rail
• 24Vdc power supply
The D1-15 has 9 inputs for the detection of 6 analog signals (0-10 V or 0/4-20 mA) and 3 temperature using Pt100 2/3-wire sensors with automatic compensation of line resistance;
the ramp conversion circuit ensures stable readings with 15-bit resolution and accuracy.
The module does not require calibration and retains the characteristics of accuracy during life time.
an internal watch-dog circuit ensures continuity of operation.
Type of interface (RS422 or RS485), communication protocol (Modbus ASCII or RTU) and address (1 to 31) are set directly through microswitches.
the module is suited for mounting on DIN rail.
