Product Description:

The CSH01.1C-PL-EN2-EN2-NNN-S1-S-NN-FW is a controller module built by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It occupies the control section in a modular drive stack, receiving field-level I/O and encoder data before forwarding calculated motion commands to attached power units. In an automation line, this device coordinates axis movement, safety reactions, and diagnostic feedback so that motors, sensors, and higher-level PLCs exchange data in real time. Because it serves the control section rather than the power section, it handles signal processing and coordination without directly supplying motor current.

The unit is energized from a 24 V DC cabinet bus, and its logic circuitry draws a baseline of 7.5 W, a figure useful when calculating UPS capacity. Command signals are delivered through a Parallel Interface, and the board provides 16 parallel inputs plus 16 parallel outputs for fast bit-level coordination of limit switches, actuators, or interlocks. The parallel I/O is suited to deterministic on and off signaling where response time matters more than packet-based messaging. Each output can switch up to 24 V DC at 0.5 A, while an internal relay contact is rated for 24 V DC at 1 A to drive external contactors. A safety layer labeled Safety Technology I/O accepts 24 V nominal signals at 3 mA and passes them to dedicated safety outputs, keeping emergency-stop chains independent of standard cyclic traffic. Configuration is handled through an RJ-45, 8-pin engineering port that follows the 100Base-TX Ethernet standard, allowing a direct connection without proprietary adapters. Timing-critical tasks such as pulse-enabled braking are supported with a maximum pulse width of 100 ms, and initial energization is limited by an inrush current clamp.

Feedback from rotary or linear encoders enters on channels that process EnDat 2.1 / 1 Vpp / 5 V TTL signals. This feedback arrangement allows the controller to read position information from compatible measuring systems during motion control. The sense line supplies a stabilized 5.0 V reference at up to 350 mA, letting the drive power most standard encoders without external supplies. During startup, the current spike is held to 4 A, preventing nuisance trips on oversensitive supply breakers.
