Product Description:
The CSH01.1C-NN-ENS-EN2-MD1-NN-S-NN-FW is a control section from Bosch Rexroth Indramat's CSH Advanced Controllers series. Installed in an IndraDrive stack, it executes motion logic, manages feedback, and exchanges setpoints with the attached power stage so coordinated axes can run in assembly, packaging, and material-handling equipment. By combining fast processor cycles with built-in field I/O, the unit links machine sensors and actuators to higher-level PLC or networked control systems. This arrangement lets the controller process command data, feedback evaluation, and local machine signals in one module within the drive stack.
An analog input resistance of 160 kOhm minimizes loading on strain gauges or potentiometers connected to the board. Digital inputs switch cleanly because the off threshold is 5 V and the on threshold is 15 V, which helps maintain noise immunity on long cable runs. Eight transistor outputs can source up to 0.5 A each, allowing direct control of valve coils, indicator lamps, and other low-power devices without external amplifiers. Base power consumption is limited to 7.5 W, which helps keep enclosure heat low during continuous use. The form-C relay pair and the additional MD1 input and output channels expand the number of field signals that can be handled directly by the controller. These resources support direct connection of switches, reference sensors, and simple actuators without moving those signals to a separate remote I/O block.
The encoder subsystems provide isolated power and filtering, which helps separate feedback circuits from other control wiring. The EN2 rail supplies sensors with 5.0 VDC at up to 350 mA, and the ENS interface uses a cutoff frequency of 500 kHz to support stable signal transmission. For encoders that need a higher supply, a separate 11.6 VDC line can deliver 500 mA. During power-up, the controller draws an inrush current of 4 A for 100 ms, so the connected supply must tolerate a brief startup surge. The onboard relay is rated for 30 VDC at 1 A for dry-contact switching of low-power field devices.
