BACnet IO module iSMA-B-8U

The module iSMA-B-8U has 8xUI (Universal Inputs). UI can work in 5 different modes: temperature, voltage, current, resistance, dry contact.

The module is factory-equipped with the two most popular open communication protocols: Modbus ASCII/RTU and BACnet MSTP, which are selected using DIP switches.

Addressing the modules is via rotary switches, which facilitates and accelerates the process of commissioning the system

8x Universal Inputs (8UI)

All universal inputs have 16-bit resolution which support the following types of inputs:

• Temperature input support the following types of sensors: 10K3A1, 10K4A1, Carel 10K, 20K6A1, 2.2K3A1, 3K3A1, 30K6A1, SIE1, TAC1, SAT1, Pt1000, Ni1000
  For sensor Pt1000 and Ni1000 use only 16bit resolution
• Voltage input 0-10 V DC: input resistance 100 kΩ accuracy ±0,1% measurement resolution 3 mV @ 12bit and 1 mV @ 16bit
• Current input 0-20 mA
• Resistive input 0-1000 kΩ: measurement resolution for 20 kΩ load 20 Ω @ 12bit and 1 Ω @ 16bit
• Dry contact input
