Data acquisition server & gateway connects up to 64 Modbus-RTU devices via RS485 & USB port, plus 100 Modbus TCP/IP devices. Supports BACnet-MS/TP, & BACnet-IP, Mbus, MQTT, RSTP, SNMP, HTTP/HTTPS; includes dual Ethernet, WiFi, & 8GB onboard memory & webserver access.

Wireless RS485 mesh transceiver connects to a Modbus-RTU device with an RS485 port. Enables a multipoint, wireless, optimized RS485 network across 1000ft (305m) indoor/4 miles (6.5km) outdoors. Compliant with 128-bit encryption. Choose 900MHz or 868MHz frequency.

WiFi + Dual Ethernet Module for Acuvim II and Acuvim-L. Supports industrial protocols including RSTP, IEC 61850, DNP 3.0 V2, Modbus-TCP/IP, BACnet-IP, EtherNet/IP, SNMP, HTTP/HTTPs Post, & more. 8GB memory with 50ms logging interval and a built-in webserver guarantee easy, secure data access.

Fiber optics module for Acuvim II and Acvuim-L with integrated fiber optic LC port, Ethernet, & WiFi communications. Supports multiple protocols like Modbus-TCP/IP, BACnet-IP, DNP 3.0 V2, IEC 61850, & more. 8GB memory with 50ms logging interval and HTTPs data encryption to cloud server ensure secure data backup.

Ethernet module for Acuvim II. Supports common protocols like Modbus-TCP/IP, SNMP V2, DNP 3.0 V2, SMTP, HTTP/HTTPs Post, sFTP Server, & more. Industry-leading 100ms response rate via Modbus-TCP/IP plus secure HTTPs data encryption. 4GB onboard memory with 15-second interval datalogging ensures data integrity.

Add PROFIBUS-DP (V0) protocol to the Acuvim II and Acuvim-L with the AXM-PROFI module. Baud rate adapts from 9.6 kbps to 12 Mbps for simple integration into process & automation environments. PROFIBUS module must be a slave on the network with an address range between 0-126.

The AXM-RS485 module provides a second RS485 port for Acuvim II and Acuvim-L meter. The second port can be used simultaneously with the built-in serial port and operates using Modbus-RTU protocol. Connect up to 32 devices so a single bus without the need for repeaters.

Expansion modules for the AcuDC 240 DC energy meter. Option to add digital I/O, relay outputs, analog I/O, or a Hall effect sensor power supply.
