Product details

What this CIM module does in the panel

The Siemens 6ED1055-5MC08-0BA1 is a LOGO! CIM communication interface module rated for -40 to 70 °C ambient, which covers unheated outdoor cabinets or refrigerated environments without derating. It adds Modbus RTU connectivity (RS232/485) to a LOGO! 8 base unit and includes a four-port industrial Ethernet switch for daisy-chaining additional devices or the local HMI. The module includes a mini PCIe interface, but the expansion card and antennas are not supplied.

Physical and power integration

Accepts 12 V DC or 24 V DC on the same terminals; the supply range is 10.2 to 28.8 V DC. Maximum current draw is 1 A, so a standard LOGO! Power or external 24 V supply handles it. FW updates are supported, and the module ships with firmware V1.0.0. The RUN/STOP LED gives immediate status on power-up.

Frequently asked questions

What is the ambient temperature range?

-40 to 70 °C ambient. The lower limit suits cold storage or north-facing outdoor panels; the upper limit covers most industrial cabinets with passive ventilation.

What compliance certifications does it carry?

cULus, CE, FM, KC, UL, EAC, and RCM. No marine approval, so not intended for shipboard use.

Will the 6ED1055-5MC08-0BA1 drop into a panel that was wired for the 6AG1055-1MB00-7BA2?

No. The 6AG1055-1MB00-7BA2 is a digital I/O module with 4 inputs and 4 relay outputs, not a communication interface. Rewiring and a different LOGO! base configuration would be required.

Does the module include a 4G modem?

No. It has a mini PCIe interface for a 4G/LTE module, but the module and antennas are ordered separately.
