Meterbus to EIA-485 Adapter (MRC-1)
Item Number:
MRC1-MNS
Packaging Unit:
1 / each
- Enables Morningstar controllers or inverters with a Meterbus™ port, but no RS-232 or EIA-485 serial communications ports to connect to an EIA-485 network
- Can also be used for EIA-485 communications with any third-party hardware that supports Modbus communication
- Includes an ON/OFF power switch. With the MRC-1 power switch on, the Meterbus device can provide a limited amount of EIA-485 network bus power (12V) for other Morningstar devices
- The MRC-1 eliminates the need to use an MSC (Meterbus to 232) paired with an RSC (232 to 485) to convert from Meterbus to EIA 485
- Fully isolated between 485 bus and meterbus (controller side)
Product Information
Product specification
The Meterbus-485 Adapter (Model: MRC-1), with RJ-11 cable included, converts the Morningstar MeterBus RJ-11 electrical interface to a standard EIA-485 interface. This allows Morningstar controllers or inverters with a MeterbusTM port, but without an EIA-485 communications port, to network with Morningstar EIA-485 devices like the GenStar and TriStar MPPT controllers. The MRC-1 can also be used for EIA-485 communications with any 3rd party hardware that supports Modbus communication.
- Status LED for monitoring and diagnostics
- Molded tabs for attachment to 35mm standard DIN rail
- Includes RJ-11 cable and removable four (4) position EIA-485 terminal Electronic Protections: reverse-polarity and short circuit protection (at the EIA-485 terminals)
- Terminal Miswire Protection: (applying bus power to A/B in some combination)
