Product Description:
The RMC02.2-2E-1A belongs to the RECO Drive Modules series produced by Bosch Rexroth Indramat. It serves as an analog measurement and actuation unit that conditions process signals so Indramat drive controllers can monitor flow, pressure, or temperature loops inside automated machinery. Two isolated input channels and one isolated output channel allow the module to collect transducer data and send control currents while maintaining galvanic separation between field wiring and the internal system bus.
On the acquisition side, a 250 Ω burden resistor terminates current loops, and the module finishes an A/D conversion in 35 µs. Each input accepts ±20 mA or selectable ranges of ±0.5/±1/±5/±10 V, so one board can handle either current or voltage devices. The two inputs are scanned in sequence, and galvanic isolation blocks ground offsets between channels and the system electronics. Built-in linearization supports Pt100 probes from -100 to +850 °C through a dedicated sensor source, and an internal range of 0 to 2000 Ω supports common RTD measurements. Accuracy on the 10 V range stays within 0.2% of full scale. For the single output, the D/A path refreshes in <5 µs, which supports fast analog updates.
The analog output delivers a span of 0–20 mA, scaled at 9.77 µA/increment through a 12 bit converter, so the module can provide fine current steps to a connected control input. When voltage mode is selected, the channel supplies ±10 V with the same accuracy class as the input side. The module’s 41.3 mm front width conserves rack space, and its 214 mm overall height matches the RECO backplane profile for uniform airflow. Protective channel isolation separates output ground from both inputs, limiting noise coupling between measurement circuits and the control signal. The channel can be used with current-based or voltage-based reference inputs, depending on the connected device.
