Description
For supplying a HIMA system there are two different potentials available:
L+ positive pole
L – negative pole (reference pole)
The positive pole is usable also for power voltage and control voltage. To achieve the valid values for the connection of single phase mains supplies, power supply units with bridge rectification and smoothing are required or stabilized power supply units. With using of HIMA standard power supplies, the potential L+ met the requirements according to the NAMUR standard NE 21 to compensate voltage dips up to 20 ms per second.
The central devices of the family H41q have decoupling and buffering during voltage dips. Disturbances within the I/O level will be suppressed by the noise blanking.
Lamp loads with high starting current (7 … 10 fold nominal current) are uncritical for HIMA power supplies with correct dimensioning.

All input/output modules can be used with both redundant and single channel models of the central devices.
The H51q system family consists of one 19 inch central rack 5 units high and up to 16 input/output racks in the 19 inch size 4 units high.
The central rack contains the following components:
– One or two (depends on the model) microprocessor-controlled central modules
– Up to three coprocessor modules, assigned to each central module
– Up to 8 interfaces RS 485 (2 on the central modules and 2 on each of up to 3 coprcessor modules) allows the connection of other systems resp. to built-up bus systems with PLC master with a transmission rate of up to 57600 bps
– One to three power supply modules 24 V DC/5 V DC to generate the 5 V DC operating voltage for the central modules and the control voltage for the input/output modules
– Power supply monitoring module with batteries to buffer the sRAM area and the real-time clock on the central modules
– Integrated cable tray
– Additional modules to connect and to decouple the supply voltage 24 V DC, to supply the watchdog signal and as fan plug-in unit with fuse and fan run monitoring .
One I/O rack contains:
– Up to 4 power distribution modules to protect the input/output circuits
– One coupling module to connect the I/O bus, with fail-safe switch off of the watchdog signal in the case of a fault
– A maximum of 16 slots for input and output modules for digital and analogue signals.
