DC-DI I/O module for digital input with passive 24V inputs

Digital Outputs

The digital output module is required for switching valves, reflux separators, heaters, contactors etc. directly via the DC-Manager.

The pulse-width modulated output allows quasi-continuous direct control of heaters, motorized control valves, etc.. Thus, there is no necessity for expensive additional control electronics.

The pulse area modulation is an extended form of pulse frequency modulation (XPFM) which minimises the pulse amount and consequently prevents damage to the actuator (e.g. a solenoid or reflux separator).

  • For direct connection of proportional solenoids

DC-BCUO I/O module bus coupler outputs for DC-Manager

HiBus Bus Coupler Input

Bus coupler input module for the connection of a sub-station (group) to a DC-Manager by HiBus.

The bus couple input module is monitored by a hardware watchdog circuit and brings the system in disorders in a safe state, e.g. by cutting off the supply to the connected peripherals. In addition, every I / O module automatically applies appropriate security measures in the event of a fault.

Each bus coupling module uses its own activation voltages for the subordinate I/O modules, making it independent of the main segment.

The DC-Manager requires a DC-BCUO connection module and a DC-BCUI plug-in module for the substation.
