BGI-144-FBar Graph Indicator for Single fixed Input with 2 to 4 relay outputs

Description :

Libratherm offers Microcontroller based universal or single / two fixed input Bar Graph Process Indicator model BGI-144 with both Digital and Bar graph indications. In addition, the instrument provides analogue retransmission output of 4-20mA with built in 24VDC loop supply to power external loop transmitter. The process value is converted into equivalent 0 to 100% value and is displayed on the bar graph using 51 red LEDs for each input with 2% resolution per LED. Two to Four relay outputs are also provided which can be used for high and low alarms for single or dual input. Serial communication on RS485, 2 wire with MODBUS RTU protocol is also available with programmable Modbus ID in slave mode. BGI-144 is available in 144 x 72 x 120mm panel mounting enclosure with ABS bazel, polycarbonate graphics and metal enclosure. BGI-144 works on 90 to 250VAC supply.
