Product Description:

The CSH01.1C-PL-EN2-EN2-MD1-S1-S-NN-FW is a control section produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in IndraDrive units, the module coordinates motion tasks, manages field-level I/O, and exchanges data with a higher-level PLC through its parallel interface. By combining analog processing, digital safety channels, and encoder evaluation on one card, it supplies deterministic command and feedback handling for packaging machines, assembly lines, and material-handling axes. The control section serves as the signal-processing layer inside the drive and supports coordinated axis behavior during automated machine cycles.

The analog circuitry accepts an input swing of ±10 V for speed or torque reference and delivers a regulated output of 5 V / 1 mA for drive-internal monitoring. Two encoder ports support 2 x EnDat 2.1 / 1 Vpp / 5 V TTL signals, allowing the module to read position feedback directly from compatible sensors. The board draws only 7.5 W at idle, which helps limit enclosure heat, yet it can withstand an inrush of 4 A when the drive is energized. Up to two probe inputs capture position events with a maximum accepted pulse of 100 ms, which supports edge-triggered measurements on slow or intermittent processes. Integrating analog reference handling and encoder evaluation on the same module reduces the need for separate signal-conditioning hardware inside the drive.

Discrete connectivity is split across several blocks. The MD1 extension provides 12 inputs and 8 outputs, while the on-board terminals add 11 inputs with 4 outputs, and the parallel header exposes 16 inputs / 16 outputs for fast bit-level handshaking. Safety channels follow EN 954-1 category requirements: each input is limited to 24 V / 3 mA, each solid-state output delivers 24 V / 0.5 A, and the redundant relay contacts are rated at 24 VDC / 1 A. This arrangement allows the control section to exchange status signals, receive interlocks, and react quickly to machine events without relying on external timing modules.
