CSH01.1C-SE-EN1-NNN-NNN-S2-S-XP-FW

The CSH01.1C-SE-EN1-NNN-NNN-S2-S-XP-FW control section belongs to the CSH Advanced Controllers series produced by Bosch Rexroth Indramat. It plugs into an IndraDrive power unit and adds application-specific logic, fieldbus connectivity, and discrete I/O handling for coordinated motion tasks in industrial automation. Inside a cabinet, the module manages sensor feedback and issues drive commands, acting as the central processing element that links machine tooling, conveyors, or packaging axes to higher-level PLC systems.

Its low-voltage domain is centered on a nominal I/O supply of 24 V, allowing direct connection to common industrial power supplies. Under steady state the electronics draw only 7.5 W, so heat dissipation remains modest and cabinet ventilation requirements are minimal. Each transistorized digital output can source up to 500 mA, while the combined current across all outputs must stay within 1000 mA; these limits define the choice of load devices such as solenoid valves or pilot relays. During power-up the board exhibits a typical inrush of 4 A, so upstream fusing and supply decoupling should be rated to handle this brief surge without nuisance tripping.

The output stage also withstands transient energy returned by inductive loads; a single pulse may reach 400 mJ without damaging the suppression circuitry. Start-up timing is characterized by a maximum inrush pulse width of 100 ms, which guides engineers when sizing supply holdup capacitors. Integrated change-over relays are present for hard-wired feedback and safety loops; each relay can switch up to 1 A of direct current at voltages not exceeding 30 V. These electrical boundaries enable the controller to drive contactors, signal lamps, and end-stop sensors while keeping electromagnetic interference and contact wear within predictable limits.
