Product Description:

The CSH01.1C-PL-EN1-EN2-MD1-NN-S-NN-FW is a controller section produced by Bosch Rexroth Indramat within the CSH Advanced Controllers series. Designed for installation in drive inverters, the unit acts as the logical core that blends field-level I/O with axis feedback so higher-level PLCs can issue deterministic commands. Inside an automation cabinet, it provides the task scheduling, encoder evaluation, and signal conditioning required to keep motion sequences synchronized with machine sensors.

Control data reach the CSH section through a Parallel Interface that handles sixteen command lines, and each line is terminated by an input resistance of 160 kΩ to reduce the load on upstream electronics. The digital inputs draw 3 mA at a logic level of 24 V, which helps limit field power demand. Two encoder supplies are provided: 8 V for En1 channels and 5 V for En2 channels, allowing the board to support either TTL or sine-wave sensors without external regulators. The card also offers sixteen parallel inputs, sixteen parallel outputs, twelve Md1 inputs, eight Md1 outputs, and two probe inputs for direct wiring of switches and relays.

The first feedback port is wired for a Resolver / HSF encoder, allowing the controller to process position data at high carrier frequencies without external converters. Output stages are sized for field devices that need up to 0.5 A per channel, and they switch at the same 24 V rail used for logic power, which reduces the number of supply domains in the cabinet. A single-line display on the front panel shows axis status, error codes, and operating modes during setup. The controller can route captured probe edges directly to the communication bus, release sourcing lines only after the corresponding inputs are validated, and assert diagnostic bits for remote health checks without burdening the higher-level PLC.
