Programable Process Indicator

Introduction:

LTRON-48E series Indicators and ON-Off Controllers are OEM series ECO range microprocesser based panel mounted indicators and on-off controller with optional input rotransmission optional. Though cost effective, there are full-featured in terms of universal inputs, programming and calibration from keyboard, and useful option of isolated input retransmission output. All functions (operation, input/range configuration and calibration) are done from keyboard.

LTRON-48E serices instruments accept Pt-100 RTD. thermocouples . 0/4-20mA (linear/square-root) inputs and is useful for all general purpose measurement, on-off control and alarm function for all process variables such as temperature , pressure, flow, level, etc.

• The instrument compact and highly functional fascia consists of a 4 digit 7-segment LED display and 4-key membrane keyboard for programming/parameter selection purpose.
• the instrument compact and highly functional fascia consista of a 4 digit 7-segment LED Display and 4-key membrane keyboard for programming/parameter selection purposes.

The instruments are innovating with compact depth (behing panel) only 75mm, moulded ABS enclosures, integral terminals and 3 sizes (1/4 and 1/8 Din). 4-20mA isolated re-transmission signal is optinal for recording/remote signal transmission applications. 2Nos NO/NC Relays are optional.

Application:

• Heating Controls in Ovens, furnaces, dryer etc.
• Cooling controls in AC&R, Refigeration.
• Process indication and alarm functions for level, pressure, flow, pH, etc used in conjunction with respective transmitters.
