Product Description

The RMG12.2-NN Interbus Gateway Module is developed by Bosch Rexroth to facilitate communication between industrial control systems. Using the INTERBUS standard, the module lets field devices and central control units send and receive serial data. The small housing and standard connectors make it easy to integrate into DIN rail systems with little wiring work.

The RMG12.2-NN INTERBUS gateway module has DB9 serial connectors with X1 and X3 as input ports and X2 and X4 as output ports. These connectors allow serial communication, most likely RS-232 or RS-485. On the left and right sides of the power link are green terminal blocks with +UL and 0V terminals. The module works with a 24 VDC supply power, and the voltage range it can handle is from 19.5 V to 28.5 V. The main line can have no more than 4 Vss of ripple. A rotating switch labeled S1 is in the center, allowing users to configure the decimal range from 0 to 9. There are four LEDs on the front panel, one for each IN port. They are labeled UL, RC, BA, and RD, and they show the status of the supply, communication, bus activity, and data receiving, in that order. On the left, a 7-segment monitor marked H1 shows address settings or diagnostic codes so that the device can be quickly identified.

The RMG12.2-NN INTERBUS gateway module has an organized interface that makes it easier to send and receive data through IN and OUT ports that keep the signal going in serial bus systems. During use, the device uses 5 W of power and has an IP20 rating for security. The RECO series makes sure that all units that work together have the same connectivity and configuration options. For consistent placement, the module has clear labels that are in line with standard wiring practices.

Frequently Asked Questions about RMG12.2-NN

Q: Does RMG12.2-NN support both RS-232 and RS-485?

A: RMG12.2-NN includes DB9 connectors likely compatible with RS-232/RS-485. This allows flexible connection to different serial communication devices in the system.

Q: How do the LED indicators help on RMG12.2-NN?

A: The four LEDs per input show real-time power, communication, bus activity, and data reception. This supports diagnostics and simplifies maintenance.

Q: Why does RMG12.2-NN use 3-position terminal blocks?

A: The +UL and 0V terminal layout provides secure and standardized power input. It simplifies power distribution and ensures consistent wiring.

Q: Do the IN/OUT ports on RMG12.2-NN enable looping?

A: Yes, X1/X3 (IN) and X2/X4 (OUT) allow daisy-chaining devices. This supports serial communication continuity across multiple modules.

Q: How does the IP20 rating affect RMG12.2-NN installation?

A: The IP20 rating requires installation in a protected enclosure. It offers basic protection against solid objects but not against liquids or dust.
