DATRAN XL4 RTU – Owners Manual – v1.1 June 2012 Functional Description Central Processor Core The Q04 ARM Processor Module is based around industry standard 32 bit ARM Micro-controller architecture. The ARM processor is an NXP LPC2468 microcontroller implemented on a four layer printed circuit board running at a clock frequency of 72MHz with fully implemented 32 bit address and data busses. The ARM processor has 96 kBytes of SRAM used exclusively by the integrated processor peripherals and core functions.
DATRAN XL4 RTU – Owners Manual – v1.1 June 2012 Connections The following connection ports available on the XL4: RS485 Port The connector used for the RS485 port looks similar to the one used on the Q03. Care must be taken! The connectors are NOT the same. Forcing a plug intended for a Q03 into a Q04 can damage the socket. The RS485 port is used for inter-module long distance, high speed communications. The RS485 port features 2,500Volt galvanic isolation and both 2 and 4 wire operation.

Functional Descriptions The photograph and diagram below shows the generalised layout of the Q22 DATRAN I/O board and can be used to locate and identify the various parts and functions detailed in this section. Q22 – DATRAN XL4 I/O Board (revision D) Many of the XL4 RTU functions inter-relate with the application software. Workbench, the Configuration & Diagnostic tool.
DATRAN XL4 RTU – Owners Manual – v1.1 June 2012 System Status LEDs There are 8 System Status LED’s on the front panel of the DATRAN XL4 RTU. The LEDs indicate the following status information: ON This blue LED indicates that power is applied to the XL4 RTU. If power is connected and the LED is not on this could indicate that the supply voltage is low or that the Q22 fuse has blown OK This green LED flashes at a slow regular interval to indicate that the Q04 Processor is running.
DATRAN XL4 RTU – Owners Manual – v1.1 June 2012 channel 8 can be configured as a high speed pulse counter, allowing pulses with duration less than 20 ms to be detected. Please contact QTech for application specific details. Note that the digital input status LEDs are controlled by the Q04 Processor and are not connected electrically in any way with the input circuitry. The diagram below shows the electronic circuitry of an individual digital input channel.
DATRAN XL4 RTU – Owners Manual – v1.1 June 2012 Circuit details of a Digital Output Channel. The digital output MOSFET transistors have an ON resistance of typically 1 ohm and are capable of switching 3 amps at 5.5 to 26.5 volts. The output voltage is clamped at 65 volts to help reduce the effects of voltage spikes when switching inductive loads. It is still recommended good practice that such loads be fitted with their own fly back or free-wheeling diode. Note.
DATRAN XL4 RTU – Owners Manual – v1.1 June 2012 Location of Digital Outputs Over-Current Jumper J28. Open Circuit Detection The DATRAN XL4 can detect if there is a load connected to each digital output channel. It achieves this by sourcing a 50uA sensing current through each digital output channel when they are in the OFF state. Fault Status Reporting The DATRAN XL4 can be configured to display Output Protection and Open Circuit Detection status information on the status LEDs.
DATRAN XL4 RTU – Owners Manual – v1.1 June 2012 Analog I/O Modes The table shows that channel pairs 1 & 2 and 3 & 4 can be configured as differential inputs, and that only channels 5 and 6 can be configured as outputs. Analogue I/O port mode settings Channel No Single Ended Input 1 2 3 4 5 6 Differential Input Single Ended Output Note. The voltage applied to an analog input channel should never be greater than 15V or less than 0V. Note.
DATRAN XL4 RTU – Owners Manual – v1.1 June 2012 Analog Inputs Single Ended or Differential Configuration Analog input channel pairs 1 & 2 and 3 & 4 can be individually configured to become differential inputs. In this configuration channel 1 and 3 are the positive inputs, and channel 2 and 4 are the negative inputs. Note. Differential analog inputs provide for non ground referenced negative inputs and provide up to 10 volts common mode rejection on analog input signals. Note.
DATRAN XL4 RTU – Owners Manual – v1.1 June 2012 Circuit details of Differential Analog Input Channel. It can be seen from the above diagram that the analog preconditioning networks are identical to those in the single ended input circuit. Therefore the various analog input mode configurations and jumper settings are the same as for the single ended analog input circuit. The op-amp is configured as a unity gain differential amplifier.
