MIX38 provides 8UI, 12DI, 6AO and 12DO and supports Modbus RTU/ASCII or BACnet MSTP communication protocol. The advantage of using two open communication standards allows use its in both new and existing installations as a part of BMS.

Additionally MIX38 provides rotary switches for setting the address, which simplifies and speeds up the implementation process. Effective processor with ARM Cortex M3 core allows fast communication and ensures no delays during data transfer. The module is mounted in a housing adapted for DIN rail mounting or directly on a panel. Separate, easy to remove connectors allow quick wiring without removing the entire module.

In addition, used labeled connectors help installation / replacement process. To increase the versatility of the module, all relay outputs allow direct control of 230 VAC (max. 3A) which eliminate requirements of additional relays, resulting in big savings.

8xUniversal Inputs (8UI)


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