4 Overview The model 55 potentiometer analog input module adds eight potentiometer analog inputs to the 5000 Series input/output system. Up to sixteen model 55 modules may be connected to the I/O bus for a total of potentiometer analog inputs per bus. The potentiometer analog inputs can be used as analog input simulators, or as a low cost configuration or input device. The Model 55 utilizes a -bit successive approximation analog to digital converter. A single chip microcontroller with integral watchdog timer operates the A/D and controls communication over the I/O bus. 55 Potentiometer Analog Input - Hardware Manual October 9, 007 3

5 Important Safety Information Power, input and output (i/o) wiring must be in accordance with Class I, Division wiring methods Article 50- (b) of the National Electrical Code, NFPA 70 for installations in the U.S., or as specified in Section -J of the Canadian Electrical Code for installations within Canada and in accordance with the authority having jurisdiction. WARNING! EXPLOSION HAZARD - SUBSTITUTION OF COMPONENTS MAY IMPAIR SUITABILITY FOR CLASS, DIVISION. WARNING! EXPLOSION HAZARD WHEN IN HAZARDOUS LOCATIONS, TURN OFF POWER BEFORE REPLACING OR WIRING MODULES. WARNING! EXPLOSION HAZARD - DO NOT DISCONNECT EQUIPMENT UNLESS POWER HAS BEEN SWITCHED OFF OR THE AREA IS KNOWN TO BE NONHAZARDOUS. 55 Potentiometer Analog Input - Hardware Manual October 9, 007

6 3 Installation The installation of the 55 module requires mounting the module on the 7.5mm by 35mm DIN rail and connecting the module to the system I/O Bus. Refer to the System Configuration Guide, at the beginning of this manual, for complete information on system layout, I/O Bus cable routing and module installation. 3. Address Selection The 5000 Series I/O bus will support a maximum of forty I/O (input/output) modules Series I/O module types may be combined in any manner to the maximum supported by the controller used. The types of input and output modules available are: Digital Input modules Digital Output modules Analog Input modules Analog Output modules Counter Input modules Each type of I/O module, connected to the I/O bus, must have a unique I/O module address. Different types of I/O modules may have the same module address. The address range supported by the SmartWIRE, SCADAPack or TeleSAFE Micro6 controller module may restrict the I/O module address range. Refer to the controller manual for the maximum address supported. The three address switches labeled,, and set the base channel. The switch labeled 6 is not used. To set the address: Open all three switches by pressing down the left side of the switch. Close the switches that total to the desired address. Figure : 55 Analog Input Address Switches shows the switch setting for each of the module addresses. 55 Potentiometer Analog Input - Hardware Manual October 9, 007 5

7 How to Set Switches Determine the module address. Press the side of the switches shown in gray above. Press this side to ignore switch value Press this side to add switch value Figure : 55 Analog Input Address Switches 55 Potentiometer Analog Input - Hardware Manual October 9, 007 6

8 Operation and Maintenance This module requires no routine maintenance. If the module is not functioning correctly, contact Control Microsystems Technical Support for more information and instructions for returning the module for repair.. Input Adjustment There is one potentiometer for each analog input. The potentiometers are the multiple turn type. This provides very fine control over the analog input value. To adjust the input: Turn the potentiometer adjustment screw clockwise to increase the input value. Turn the potentiometer adjustment screw counter-clockwise to decrease the input value. The input value will stop changing when the potentiometer reaches its limits. The screw will continue to turn.. Data Format 5000 Series analog input and output modules use 6 bit signed numbers (5 bits plus sign). s with less than 6-bit resolution normalize the data into the 6-bit format. The 55 module has a bit, unipolar, analog to digital (A/D) converter. There are 096 A/D counts in the input signal range. The A/D outputs a value in the range 0 to Potentiometer Analog Input - Hardware Manual October 9, 007 7
