Product Description:

The CSH01.1C-PL-EN1-EN2-MD1-S1-S-NN-FW belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. This controller card is intended for drive-based automation where fast local processing of encoder feedback and discrete I/O is required before data is forwarded to higher-level PLCs. Within a Rexroth drive rack, it supplies encoder power, accepts mode-selection signals, and manages field wiring so that motion axes and auxiliary actuators operate in a coordinated manner. This arrangement keeps local signal handling close to the drive, which helps the control loop respond quickly to encoder changes and switching states.

The card’s base power draw is limited to 7.5 W, and a typical inrush of 4 A for 100 ms must be considered when sizing the DC supply. One analog channel can source 5 V at 1 mA for reference signals. Encoder supply rails are split: EN1 provides 8 V for TTL or HTL sensors, while EN2 offers 5.0 V with up to 350 mA to power SSI or BiSS devices. On the MD1 terminal block, the module presents 12 digital inputs and eight digital outputs for limit switches, temperature contacts, or interlocks. The PL terminal expands the available field connections with 16 inputs and 16 transistor outputs, which helps larger machines route more status and control signals through the same controller card.

A front-edge Parallel Control bus, noted as the Parallel Interface, moves status bits and command words directly to the drive processor with minimal protocol latency. For interposing loads, the board integrates two relay channels rated at DC 24 V, 1 A, so small external devices can be switched without a separate relay module. The S1 header accommodates four mode-select inputs, and the same connector can deliver up to 1.6 A to small external devices. A single-line display provides basic diagnostics at the front of the card. This local display presents status information directly at the unit during operation.
