Product Description:
The CSH02.1B-CC-EC-PB-NN-EC-NN-FW is a controller card produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in Rexroth multi-axis drive systems, it supervises position, velocity, and process I/O while exchanging data with higher-level PLCs over Profibus. The module supplies regulated excitation to encoders, scans analog and digital feedback signals, and issues motion commands that keep servo drives synchronized during automated machining, packaging, or handling tasks. In machine applications, that arrangement lets the card link encoder feedback, logic-level I/O, and fieldbus communication within the same control path.
This controller operates from a control-logic feed of 24 V DC and draws only 17 W, so cabinet heat rise and power-supply loading remain low. Its sine-wave acquisition channel has a resolution of 12 bit, allowing fine interpolation of incremental encoder tracks, and the logic can process square-wave feedback up to 1000 kHz without losing edge information. That combination supports stable position evaluation on both slower servo axes and faster motor feedback channels. As a result, the card can accept varied feedback formats without external conversion modules.
The encoder power budget is rated at 6 W, letting the board energize multiple 5 V or 12 V transducers simultaneously. Voltage inputs are digitized with 14 bit resolution and enter through a 300 kΩ impedance path that minimizes sensor loading during measurement. Two onboard relays can switch up to 1000 mA at 30 V for brakes or contactors, while analog outputs step in increments of 24 mV/incr to command external amplifiers. For network extension, the integrated Profibus repeater draws only 75 mA, which helps support long bus runs and distributed nodes without adding much demand to the control supply.
