Product Description:

The CSH01.1C-CO-ENS-NNN-MEM-NN-S-NN-FW control unit belongs to the CSH Advanced Controllers series from Bosch Rexroth Indramat. It is a modular drive controller card used within IndraDrive systems to process axis commands, handle fieldbus communication, and generate the real-time signals that govern servo amplifiers in automated machinery. By hosting dedicated communication layers and encoder channels on a single plug-in module, the unit simplifies cabinet wiring and shortens loop times in multi-axis industrial automation tasks.

The analog input stage presents an impedance of 160 kΩ, allowing standard process transmitters to deliver position or speed references without loading the signal source. Its configurable analog output can source up to 1 mA and delivers a fixed reference of +5 V, so external feedback devices can be powered or test points can be monitored directly from the card. When discrete control is required, each transistorized digital output can switch up to 0.5 A, which is sufficient for contactors or optical couplers. Despite this I/O density, the unit occupies only 241 × 49.5 × 103 mm, making side-by-side stacking possible in compact enclosures. The integrated ENS encoder port provides a regulated supply of 12 V for SinCos or TTL sensors connected through its D-Sub interface.

The MEM diagnostic channel accepts extension cables up to 40 m, and the double shielding used for this link helps reject ambient noise at high servo switching frequencies. Control outputs that must remain galvanically isolated can be routed through the on-board relay, which is rated for DC 24 V / 1 A and suits brake release coils or status lamps. Command exchange with higher-level PLCs is handled over CANopen or DeviceNet, while parameter download and service access use the RS232 serial port. The card is supplied without integrated safety technology, and encoder emulation keeps position data available for auxiliary drives.
