iSMA MIX18 IO Module
The iSMA MIX18 module has been equipped with the most commonly used types of I/O in building automation (MIX of all types of I/O in one unit).
The iSMA MIX18 has 5xUI (Universal Inputs), 5xDI (Digital Inputs), 4xAO (Analog Outputs) and 4xDO (Digital Outputs).
Protocols: Modbus ASCII/RTU and BACnet MSTP
Product Description
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. Built-in mini USB allows for initial configuration of the unit without power supply.
5xUniversal Inputs (5UI)
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
5xDigital Inputs (5DI)
- Dry contact inputs
- Fast pulse counter up to 100 Hz save in EEPROM memory
4xAnalog Outputs (4AO)
