About the productiSMA-B-4U4A-H has 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 module is factory-equipped with the two most popular open communication protocols: Modbus ASCII/RTU andBACnet MSTP, which are selected using DIP switches.
Addressing the modules is via rotary switches, which facilitates and accelerates the process of commissioning the system.
This module is fully compatible with any Modbus or Bacnet system including the following: Tridium Jace3, Jace6, Jace8000 Compatible, Trend IQ3, IQ4 Bacnet IP Compatible, Siemens PX range, Cylon Bacnet controllers, Schneider Electric StruxureWare Bacnet controllers, OSS NeOSS building management controller, Priva Blue ID, Distech EC Bos, DELL EDGE GATEWAY 5000, Compatible with any Honeywell Centraline Hawk, Delta Controls Compatible IO ModulesInputs & Outputs
