Analog input modules are used in data gathering and proportional control applications. All modules are potted for industrial environments. They operate under high vibration (IEC68-2-6; 0.15 mm/sec 2 at 10- 150Hz) mechanical shock (IEC68-2-27; 11 mS, sinusoidal 30 gS) and high relative humidity (IEC68-2-3; 5-95% non-condensing). They feature a high level of noise immunity and accuracy. All models provide isolation from field to logic, field to power supply and module to module. OpenLine® Analog OpenLine ® analog modules communicate serially with the controller. Each module has a separate transmit and receive line that operates at 115,200 baud with no parity bits, 8 data bits, and 1 stop bit (115.2K,N,8,1). The command structure and responses for all modules are detailed in Bulletin No. 743. Each module has a microcontroller and non-volatile serial EEPROM memory. The calibration data is stored within the EEPROM, and may be changed using the appropriate commands and the 70L-PROG field calibration unit. The software provided with the calibration unit communicates with the modules through the serial port of a PC. Calibration equipment is not provided. OpenLine® Analog Input Modules Upon request, analog input modules return a 12-bit value that is right justified and packed in a 16-bit word that represents the equivalent analog value sensed. OpenLine® thermocouple inputs linearize the thermocouple reading and returns degrees to the controller. Openline® Analog Output For analog output modules, the output of these modules is zero scale on power up, then it is the analog equivalent of the 12-bit value sent to the module over the communication lines. G5 Analog Output The output (voltage or current level) of these modules varies proportionally to the 12-bit serial data string sent to them by a control circuit. The data string is typically 213.2 µSec. long as detailed in Figure 1. Once a data string is received, the output is set and remains constant until another data string is sent. Therefore, the output level of the module could be changed almost 4700 times a second. For more information on programming Grayhill analog output modules, request a copy of Bulletin No. 581. START 12 BIT DATA END 9.6µS 153.6 µS 500 µS Figure 1 Analog I/O Modules Engineering Information and Selection Chart Start Pulse: High for 6.4 µS Min., then low for 3.2 µS Data Packet: Each bit is 12.8 µS long. High for first 3.2 µS of the bit. Middle 6.4 µS determines the value of the data bit (High = 1, Low = 0). Low for last 3.2 µS of the bit. Stop Pulse: Low for 500 µS minimum Times shown are ± 10%, except minimums. SERIAL DATA FORMAT** G5 Analog Input G5 voltage or current input modules are actually frequency converters. The input to these modules is a signal from a sensor. The output from these modules is a squarewave whose frequency varies linearly from 14.4 to 72 KHz and is proportional to the input signal. The controller must be able to measure this frequency and convert it back to a signal level. G5 thermocouple modules pass through the thermocouple reading and do not linearize the signal. Linearization must take place within the controller. Agency Approvals OpenLine® analog modules are EN50082-2 and EN50081-2 compliant and meet the requirements of 89/336/EEC EMC directive. They are also EN60950 (61010-1) compliant. Meeting these requirements allows the modules to bear the CE mark. Additionally, the modules are CSA certified to CSA 22.2 No. 14-95M and CSA 22.2 No. 213-M1987 Class I, Div. 2 Groups A, B, C and D and are UL recognized to UL 508.
