PROSYSTEMY www.prosystemy.sk DCU56IO Input/output Modules Technical Specifications Input/output (I/O) modules are important part of Dynamic Control Unit. Their purpose is to connect physically DCU to controlled process through wires and pre-process electrically the signals streamed to / from DCU. There are five groups of I/O modules: - Power and communication module (only one type) - Analog output modules (type 0-10V and type 0-20mA) - Analog input modules (type 0-10V, type NTC10k, type 0-20mA, type on-measure) - Digital input modules (only one type) - Digital output modules (type 24VDC and type Relay) Each type of I/O modules has its specific purpose and is destined for a specific type of electrical signal. Modules may not be placed anywhere into DCU. Connectors on the bottom of each I/O modules determine where a module may be placed. Figure shows positions for each group of II/O modules. To (re-)place an I/O module top cover needs to be removed. I/O module can then be released/placed by pulling / pushing gently while holding screw terminal. See Figure with DCU decomposition.

Indicate status of DCU via two LED lights. Ethernet ELECTRICAL SPECIFICATIONS Input power supply 20 - 26VAC or 24-36VDC Note: Minimal acceptable voltage is 14VDC, but the following limitations has to be taken into account in such situation: A) Auxiliary power supply 24VDC is not working properly. B) Digital output modules must be DC voltage type, not relay (relays would not be switched correctly). Moreover, output voltage of these voltage digital outputs correspond to connected power supply voltage (min. 14VDC). Note: It is recommended to use separate power supply only for DCU controller and other power supplies for connected control devices sensors, actuators, Modbus devices...
