DESCRIPTION:-
LTRON-101-1B and 2B are part of Lectrotek’s LTRON-series of Universal Indicators which includes 51- and 101-segment LED Digital Bargraph Indicators products.
The instruments come in DC 4-20mA and Universal site programmable inputs versions and accept RTDs, thermocouples J.K.R.S type, 4-20 mA and 1-5V DC signal inputs.
The indicators display information in form of a LED bargraph as well as digital modes. The bargraph a analogous display for easy operation understanding at a glance, especially in high density instrumentation panels, while its 4-digit display displays the exact values in settable ranges for precise display from a close view.
Applications are general-purpose process indication in control rooms where array of digital indicators may cause distraction/confusion, whereas, bargraph indicators give an approximate indication to operator for quick information and decision making.
They are handy to replace obsolete drum or pointer scale indicators and offer advantages of universal input programmability, dual displays for comprehensive operator information,The instruments have alarm options, wherein limits can be set on process input High (exceed) or Low (fall below PV) and operate relays for alarm and/or trip functions. 2 relays per channel are available, with adjustable limit hysterisis and potential-free C/O contacts.
4-20 mA isolated retransmission signal proportional to the input signal is available as option.
Isolated RS-485 serial port is also optional, with communication as per Modbus-RTU protocol.
LTRON-2B-101 are housed in ¼ DIN-size panel mounting enclosure of bezel size 72 x 144 mm, for both Dual Loop and Single Loop versions. They mount on panel fronts through cutouts of 68x 138mm, and are fixed with 2-clamps supplied.
NOTE:-
- Single Loop Bargraph LTRON-1B-101 in bezel size 36x144 mm.
- Dual Loop Bargraph in Slim size 36x144 mm with 4-20mA input and 24VDC powered
- Circular Bargraph Indicators BRG-150.
