Product Description:

The RME12.2-16-DC024-200 is a digital input module from Bosch Rexroth Indramat that belongs to the RECO Drive Modules series. Installed in multi-axis drive racks, the unit provides galvanically isolated sensor inputs to the central controller, allowing machine states to be captured and relayed without extra wiring. Its purpose in industrial automation is to translate field switch positions, proximity signals, and status contacts into bus-readable information that can synchronize motion axes and sequence-dependent machine functions. The isolation between field wiring and the control side also helps reduce the transfer of electrical noise into the rack electronics.

All sixteen input channels share a logic resolution of 16 bits, supporting direct binary evaluation of on and off states while leaving room for diagnostic handling within the process image. Each channel operates at 24 VDC, so standard industrial PNP sensors or dry contacts can be wired without level conversion. The module offers 16 inputs and works as a local bus device type DI, occupying one word on the RECO backplane and reporting data with single-cycle latency. Communication to the higher-level controller is handled through INTERBUS, permitting addressing, parameter transfer, and cyclic exchange on the same twisted pair. A depth of 81 mm allows the enclosure to fit in shallow control cabinets while still accommodating the rear edge connector and internal opto-isolators.

The module has an overall height of 192 mm and a front panel width of 41.3 mm, giving it a narrow profile that leaves room for adjacent modules and field wiring. Inputs are separated into 2 electrically isolated groups, so circuits with different reference potentials can be connected on one module with less risk of unwanted coupling. Each group has 8 channels, which helps organize distribution wiring because one sensor supply can serve a full block of inputs. The low mass of 290 g helps limit rail loading in crowded panels, and the grouped layout keeps channel assignment easier to follow during installation and service.
