Product Description:

The CSH01.1C-SE-EN1-NNN-NNN-S2-S-XP-FW is a motion and logic controller card manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in IndraDrive power sections, the board issues position commands, evaluates local sensor states, and exchanges data with higher-level PLCs through a fiber-optic SERCOS interface. Its role in industrial automation is to synchronize servo axes and discrete I/O so that packaging, printing, or handling machines can execute repeatable, time-critical sequences. It also combines axis coordination with local signal handling on one control platform.

The controller accepts digital inputs at 24 VDC while drawing only 3 mA per channel, which helps reduce load on the connected control circuit. Each output group is limited to 1000 mA, and a single output point may deliver up to 0.5 A; the nominal output voltage matches the input control level. During startup, the card can tolerate brief inrush current before the isolated I/O supply settles into continuous operation. Inductive loads may return up to 400 mJ during switch-off events, which helps protect the output stage when coils or small solenoids are de-energized. Communication to the drive bus proceeds at up to 16 MBaud, allowing deterministic updates of motion parameters and status data.

The EN1 option consumes 6 W and the SE safety extension adds 2 W, so overall demand at the backplane reaches 7.5 W. Relay contacts on the card can switch DC loads up to 1 A DC with a minimum wetting current of 10 mA, a contact resistance of 1000 Ω, and a voltage ceiling of 30 VDC. This allows the relay section and the parallel solid-state outputs to be used on the same low-voltage control circuits. These electrical limits support mixed signal and actuation duties while keeping switching behavior predictable during repeated machine cycles.
