Description

The MGate 5121-T/KC is an industrial CAN to Modbus TCP gateway that converts CANopen, J1939 and proprietary CAN (CAN 2.0A/B) data to Modbus TCP and SNMP. This -T wide temperature model operates from -40 to 75°C and is the KC-certified variant, making it suited to harsh industrial sites and Korean market compliance requirements. The gateway acts as the CAN master and presents data to Modbus TCP clients as a Modbus TCP Server.

It pairs a single isolated CAN port with two 10/100 Ethernet ports for cascading, dual 12 to 48 VDC power inputs and a relay output. A rugged IP30 metal housing mounts on DIN rail, and a microSD slot supports configuration backup and duplication. Configuration is handled through a web console with EDS file import and CANopen auto-scan.

FAQs

Q: What does the -T in MGate 5121-T/KC mean?
A: The -T denotes the wide operating temperature model, rated for -40 to 75°C, suitable for outdoor cabinets, cold storage and other harsh environments.

Q: Which CAN protocols does this gateway support?
A: It supports CANopen (as master), J1939 and proprietary CAN using CAN 2.0A/B, all converted to Modbus TCP and SNMP.

Q: Does the gateway act as a Modbus TCP client or server?
A: On the Modbus TCP side it operates as a Modbus TCP Server (Slave), supporting up to 16 simultaneous client connections.

Q: How is the gateway powered?
A: It accepts 12 to 48 VDC on dual redundant spring-type Euroblock power inputs, with a maximum current draw of 455 mA.

Q: How is the MGate 5121-T/KC configured?
A: Configuration is done through the built-in web console over HTTPS or with the Device Search Utility (DSU). The web console supports EDS file import and CANopen auto-scan, and settings can be backed up to a microSD card.

Q: How does this model differ from the standard MGate 5121?
A: This SKU is the -T wide temperature version (-40 to 75°C) and carries the KC certification variant.
