Product Description:

The RME12.1-16-DC024 is an input module manufactured by Bosch Rexroth Indramat within the RECO Drive Modules series. Integrated into a RECO rack, the unit expands a controller with sixteen discrete input channels that capture field signals such as sensor contacts or limit switches. By translating on-machine status information into logical states for the automation bus, the module supports deterministic sequencing, safety interlocks, and general I/O concentration in industrial handling systems, packaging lines, and material flow installations.

The module is powered from a control cabinet auxiliary rail at 24 VDC, so its sensor circuits share the common low-voltage supply used by most PLC peripherals. Process data are transferred over the INTERBUS remote I/O ring, enabling time-synchronous updates alongside other Rexroth drives and actuators. All sixteen inputs are scanned in parallel, and the channel count of 16 allows one card to handle signals that would otherwise require multiple single-point terminals. Field wiring terminates on two plug-in terminal blocks labeled X1, X2, each equipped with screw contacts for secure retention during vibration. Every block contains 10 pins, providing individual signal lines plus logic-zero conductors for the reference potential.

The sixteen lines are arranged as two logical groups of 2 x 8, each routed internally in the connector pattern 8 Inputs + 2 x 0VL. Because the card is a pure Digital Input device, each channel senses only the presence or absence of the external 24 V signal, which keeps signal evaluation straightforward. Address bits assigned by the station selector map the first group to bus bytes I*.0.0 to I*.1.7, maintaining a consistent relationship between panel terminals and PLC tags. This mapping supports orderly signal assignment and preserves the deterministic scan cycle expected in modular RECO racks.
