Analogue input 3 (9033) / 6 (9015 / EX-9036) Channel module (16 bit)

14.09.2012 - Version 1.00

Introduction

The EX-9015 / EX-9033 / EX-9036 Remote IO Module is a high quality and cost-effective data collection device. ExpertDAQ remote IO modules allow virtually unlimited and completely transparent the expansion of PLCs with analog inputs via EIA485 / RS485 (optional with MODBUS RTU communication protocol). RS485 is the industry's most widely used bi-directional half-duplex bus with symmetric transmission. It allows sending and receiving high data rates over long distances.

The EX-9015 / EX-9033 / EX-9036 analogue input modules have been developed for the detection of resistance temperature sensors and can be used with all popular resistance thermometers (see table Implementation) The EX-9033 provides 3 available channels, the Models EX-9015/EX-9036 have six inputs each. The modules with designation EX-9033P/EX-9036P and the EX-9015 also possess individually configurable inputs. All modules are available with Modbus RTU communication protocol.

LED display

The EX-9015 / EX-9033 / EX-9036 are equipped with a 4.5-digits 7-segment display, which indicates the important information

INIT configuration mode

The EX-9015 / EX-9033 / EX-9036 features EEPROM, in which parameters such as device address, model, baud rate, range and other information is stored. Before commissioning the parameters usually need to be adjusted. For this purpose, the INIT mode has to be activated as follow:

Turn off the module
Connect the INIT pin to the GND pin
Turn on the module

The device is now ready to configure

Calibration

NOTE: The calibration must be performed by qualified personnel!

Calibration precedure:
Install the zero point calibration resistor
Allow the module to warm up at least 30 min
Enter the sensor’s type designation for which you want to perform the calibration (see table)
Activate the calibration
Run the zero point calibration
Install the span calibration resistor
Run the span calibration command
Repeat steps 4 through 7 three times

Notes:
Use 2-wire sensor connections to the resistance calibration
For EX-9033 / EX9036 connect the calibration resistor on channel 0
For EX-9015 / EX9033P / EX9036P each channel should be individually calibrated while the other channels are disabled during the calibration.
Prior the calibration reset the communication protocol.
For calibration use the following resistors:

Type	Zero calibration	Span calibration
20	0 Ω	320 Ω
2A / 2D	0 Ω	320 Ω

Connections

Connection recommendations
For EX-9033 / EX-9036 and EX-9033P / EX-9036P the connections of individual channel have to be shielded and the shield to be connected to the port A.GND of the channel.
For EX-9015 shielded wires are recommended. The shield should be connected to the IEXEC+ terminal of the channel.
For RS-485 use twisted wire pairs (24AWG)
Use 26-12AWG wire for signal connections

Please note that the channels 0 to 2 of EX-9015 / EX-9036 are designed for 2 / 3 / 4 wire connections. However channels 3 to 5 can only read 2 or 3 wire connections. On the EX-9033 all channels allow 2 / 3 / 4 wire connections.

When connecting inputs 0 to 5 please follow the graphics below:
