IS215UCVEH2AE Electrical module

Two serial ports are available for bi-directional asynchronous communications. Terminals NCA and NCB provide an RS485 connection for LIL or Modbus network communications. An MMJ-11 connector on the underside of the Display Assembly provides an RS232 connection for creating and editing configurations using the optional PCBased Graphical Configuration Utility. Since both ports are independent UARTs, communications with one serial port will not interfere with communications to the other. Parameters in the STATN function block allow setting of the Modbus baud rate and transmission characteristic for the Display Assembly MMJ-11 configuration port and LIL/Modbus terminals NCA/NCB. (See STATN-Station Parameters in Section 3.) Additional information on Modbus network communications and data mapping can be found in Section 6 and Section 7. The RS-232 connection uses a DEC MMJ connector with the following six connections: • RTS - Handshaking output from MPU • TXD - Data output from MPU • Common • Common • RXD - Data input to MPU • CTS - Handshaking input to MPU The on-board Power Supply circuit provides the power sources necessary for system power, internal analog output power and transmitter power. Transmitter power is +26 Vdc at 0.125 amperes, to power up six process transmitters.

I/O EXPANDER BOARD

The I/O Expander Board communicates with the Controller Board and contains hardware that increases station capability. Additional direct connected I/O includes two isolated universal analog inputs with thermocouple, RTD, resistance, slidewire, mA and voltage conversions, two additional digital inputs that can be used as discrete or frequency inputs, an additional analog output and two relay outputs. All calibration data for the Expander Board is stored in the board’s nonvolatile EEPROM making recalibration unnecessary when interchanging Expander and Controller Boards. Expander circuitry operates under the control of the MPU-based Controller Board, and like the Controller Board, it contains both analog and digital circuitry. The analog circuitry operates in real time while the digital circuitry operates at high speed under program control.

Relay 1 and Relay 2 are triggered by the off-board MPU to provide relay contact type outputs. Each SPDT relay output can be connected in a normally open or normally closed contact state. 13.4 LonWorks BOARD The LonWorks Board provides additional I/O when needed for multiple-loop applications, advanced control, or batch sequencing. This board uses the popular LonWorks (LON stands for Local Operating Network) protocol for high connectivity via a high-speed digital fieldbus to a large selection of standard I/O products. LonWorks remote I/O products include many analog input and output options as well as digital inputs and outputs using relay or solid state technology. This board plugs into the Controller Board via two connectors. An 80 pin pass-through connector is also available for stacking additional option boards.
