Power supply module

The module is used for controller's autonomous operation at facilities without electric power supply.

	Power supply module
Purpose:	The module is used for conversion of mains alternating voltage into direct stabilized voltage of controller power supply in the range of 5.. 15 V. Parameters of output voltage are adjusted during setup and commissioning works.

The power supply module can additionally supply external devices (e.g. interfaces of connected devices, such as gas volume corrector EK-260). The possibility of power supply of external devices and their quantity depends on the total power of all devices and modules of the design-configured complex.

The module has the possibility of connection of a spark protection barrier with explosion protection of supply circuits. The module ensures connection of an autonomous power supply source with organization of automatic switchover to power supply from the autonomous power supply source for the period of external power outage, with subsequent automatic switchover back when the external power is recovered.

The Design-Configured Controller configuration with the maximum functionality, supporting autonomous operation for 4 years:

• 12 analog;

• 12 discrete inputs of "dry contact" type;

• 1 digital interface (RS-232 or RS-485).

Depending on the number of connected extension modules, it is necessary to use different numbers of autonomous power supply modules:
