Product Description:

The CSH01.1C-PB-ENS-MA1-MD2-L2-S-NN-FW control section is produced by Bosch Rexroth Indramat for the CSH Advanced Controllers series. It plugs into modular drive racks and coordinates axis control, fieldbus exchange, and integrated safety. By combining encoder, analog, and high-density digital interfaces on one board, the unit acts as the command layer for industrial motion platforms that demand synchronized positioning, real-time data capture, and deterministic command distribution.

On the feedback side, an encoder port provides 12 VDC to incremental sensors, while an SSI channel offers 24 VDC at 0.2 A for absolute encoders. The MA1 option contributes 2 differential analog inputs and two analog outputs. Each input accepts signals within a ±10 V span, and the two outputs reproduce references across the same range. For plant networking, the controller relies on PROFIBUS-DP as its master interface, carried over the backplane. The MD2 extension supplies 16 sourcing digital inputs together with an equal number of transistor outputs, letting the section read limit switches and drive contactors without auxiliary relays. A dedicated RS-232 maintenance port supports data bursts up to 115 kBaud for service access.

Field wiring is simplified by the PROFIBUS port’s D-Sub, 9-pin connector, which mates directly with shielded cables. When higher-power circuits must be switched, the integrated relay accommodates 24 VDC, 1 A across its normally open contact. The safety package uses Safe Torque Off, enabling energy removal from the inverter through a monitored 24 VDC, 3 mA input. The MA1 converter uses a 12-bit A/D stage, and matching D/A resolution is used for the output channels. Logic voltage remains stable on the STO terminal, and paired MD2 outputs propagate status bits in real time to actuate pneumatic valves or signal towers during every cycle.
