iSMA Controlli Mix 38-IP
The iSMA MIX 38 IP 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 MIX 38 IP has 8xUI (Universal Inputs), 12xDI (Digital Inputs), 6xAO (Analog Outputs) and 12xDO (Digital Outputs).
Protocols: Modbus ASCII/RTU and BACnet MSTP with built-in Modbus gateway
Product Description
The module is factory-equipped with the two most popular open communication protocols: Modbus TCP/IP and BACnet IP, which are selected using DIP switches. Built-in Modbus Gateway TCP/IP to Modbus ASCII/RTU, enabling you to connect additional modules/devices that communicate via Modbus RS485. 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.
8xUniversal 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
