Description
Modbus Gateway supports the four most commonly used communication standards, RS-232/485/422, and Ethernet. The ease-of-use configuration utility provided with Modbus Gateway can quickly select the hardware interface, and easily switch to the existing communication infrastructure. You could set it up via Web Browser, Serial Console, Telnet Console, Windows Utility or through the LCM display in front of the device. Industrial EMC protection makes MB5916A ready for every mission.
16‑Port IEC61850‑3 Certified Industrial Rack‑Mount Secure Modbus Gateway, DSub‑9 or TB5 connectors, optional 3kV serial isolation, dual power input.

Which version do I need?
This page covers the MB5916A gateway. ATOP's A models (MB5908A with 8 serial ports, MB5916A with 16) are the substation versions of the MB5908/MB5916: compared with the MB5916 they add IEC 61850-3 / IEEE 1613, six Ethernet ports instead of two (RJ45 or 100BASE-X SFP options), DSub9 or terminal-block serial connectors with 3 kV isolation instead of RJ45 with 2.5 kV, a 100-370 VDC input option, redundant power and -40°C to +85°C instead of -20°C to +70°C. The MB5916A-CT is the concentrator build. Choose the SFP option for fibre links inside a substation.
Typical applications for the MB5916A
- Integrating Modbus RTU relays, meters and RTUs into a substation Modbus TCP network
- Substation automation panels requiring IEC 61850-3 / IEEE 1613 equipment
- Sites with 110 VDC or other high-voltage DC battery supplies, using the 100-370 VDC input
- Fibre-connected bays using the 100BASE-X SFP option
- Unheated outdoor kiosks and switchrooms from -40°C to +85°C
- Petrochemical and utility low-voltage switchboards with dense serial Modbus devices

MB5916A — frequently asked questions
Is the MB5916A certified for substations?
Yes. ATOP's selection guide ticks IEC 61850-3 / IEEE 1613 for the MB5916A, and it is rated -40°C to +85°C operating.
How many Ethernet and serial ports does it have?
Six Ethernet ports, available as 10/100BASE-T(X) RJ45 or 100BASE-X SFP options, two of which support RSTP redundancy, plus sixteen RS-232/422/485 serial ports on DSub9 or terminal-block connectors.
What power inputs does it take?
It has redundant power inputs, and ATOP lists 24-48 VDC, 100-240 VAC and 100-370 VDC supplies for this model, so it can run from substation DC batteries.
What is the difference between the MB5916A and the MB5916?
The MB5916 has two Ethernet ports, RJ45 serial connectors with 2.5 kV optional isolation, 24-48 VDC or 100-240 VAC input without power redundancy, and a -20°C to +70°C rating. The MB5916A adds IEC 61850-3 / IEEE 1613, six Ethernet ports, DSub9/terminal-block connectors with 3 kV optional isolation, a 100-370 VDC option, redundant power and -40°C to +85°C.
What is the difference between the MB5916A and the MB5916A-CT?
The MB5916A translates Modbus TCP requests to the serial line on demand. The MB5916A-CT is ATOP's top-of-line redundant concentrator: it polls slaves automatically into internal memory and can run as a redundant pair with automatic recovery after an Ethernet or serial link failure.
How is it configured?
Through a web browser, serial console, Telnet console or ATOP's Windows utility, or from the LCM display on the front panel.
