The Bosch Rexroth Indramat CSH01.1C-ET-EN1-ENS-EN2-S1-S-NN-FW is part of the CSH Advanced Controllers series and supports Multi-Ethernet communication via two 8-pin RJ-45 ports on 100Base-TX. The controller features three encoder interfaces, including HSF/RSF, IndraDyn/Hiperface/1 Vpp/TTL, and EnDat 2.1/1 Vpp/TTL. Safety inputs and outputs are available, such as a 24 V relay contact rated at 1 Amp and a 24 V safety output at 0.5 Amps.

Product Description:
The CSH01.1C-ET-EN1-ENS-EN2-S1-S-NN-FW is a control section card manufactured by Bosch Rexroth Indramat for the CSH Advanced Controllers series. Installed in an IndraDrive power module, it provides Multi-Ethernet connectivity while conditioning three separate encoder inputs so the drive can execute precise torque, velocity, and position loops. By translating real-time fieldbus telegrams into deterministic motion commands, the card links higher-level PLCs to servo axes that run conveyors, Cartesian robots, or infeed rollers in automated production.
The first encoder interface delivers 250 mA from an internal supply of 8.0 V to power HSF or RSF transducers, and it provides a resolver excitation of 18.2 Vpp for legacy feedback devices. A second encoder channel supports IndraDyn or Hiperface formats and can source up to 350 mA at 5.0 V, allowing mixed-technology feedback on a single axis. Two eight-pin RJ-45 sockets route the Multi-Ethernet link, and frames move across the backplane at the industrial 100Base-TX standard so synchronous position data reaches the drive within sub-millisecond cycles. Internal isolation keeps each supply rail separate, preventing encoder faults from propagating onto the network lines.
The ENS interface is sized for loads up to 500 mA and is backed by an independent 11.6 V rail, giving additional headroom for high-resolution SSI or EnDat 2.1 feedback heads. An onboard safety relay labeled S1 switches field power rated at 24 V / 1 A, while complementary 24 V logic terminals accept enabling inputs and provide monitored outputs that feed external emergency-stop chains. The controller can power separate feedback devices while handling Ethernet communication and safe torque off signaling through the same control section.
