iSMA Controlli Mini 4U4A-H-IP
The iSMA 4U4A H IPhas 4xUI (Universal Inputs) and 4xAO (Analog Outputs). UI can work in 5 different modes: temperature, voltage, current, resistance, dry contact. AO are 0-10 V DC with max. 20 mA load allow direct control of relays (12 V DC) or SSR with PWM support.
The iSMA 4U4A H IP is factory-equipped with the two most popular open communication protocols: Modbus ASCII/RTU and BACnet MSTP, which are selected using DIP switches.
Protocols: Modbus ASCII/RTU and BACnet MSTP with built-in Modbus gateway
Product Description
The iSMA 4U4A H IP are 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.
4x Universal Inputs (4UI)
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
4x Analog Outputs (4AO)
