SMW Wall Mounting Weighing Indicator and Controller

The surface mounted strain gauge display is housed in a light grey ABS case, sealed to IP65 with external dimensions of 200 x 120 x 75mm. The unit comprises a 8 digit 12.7mm LCD display, on an intelligent base unit with user configurable 4-20mA and 0-10volt analogue outputs. 'Plug-in' module positions are available for power supply, relay and communications options. The relay module provides for two set points, together with In Flight compensation. Relays can be inverted and latched, all of these facilities being set in engineering terms. Both relay and analogue outputs have a high level of isolation. A facility is available to alter the default display for Gross or Net values. The optional communications provide for 20mA noise immune current loop, RS232 and multi drop RS485 connections to a PC, PLC or mainframe. This allows for the input variable to be taken and the set up parameters changed. Communications protocol options include ASCII, MODBUS RTU and MANTRABUS. Additionally, multiple 20mA units can be connected via an IF25 current loop to RS232 interface which when included, allows for up to 250 units to be connected. The RS232 port is also available for a Time/Date or Data only printer to be connected, to log all the desired activities. Baud speeds of 300 to 19200 are programmable. Power supplies options of 115 or 230VAC and 9 to 32VDC are available.
