Product Details
SANSEL offers PI 542A Model PROCESS INDICATORs are extremely versatile Indicators that can be used for a wide variety of applications in all type of process industries. These INSTRUMENT offer extreme reliability and low cost for Process measurement and logging. PI 542A is a Microprocessor based indicator ensures accurate readings for all Linear Parameters. A number of programmable features including In-line calibration are standard. All the parameters are saved in a non volatile EEPROM memory which doesn't needs any external battery. PI 542A can offer relay outputs for signals exceeding set points, Programmable current or voltage Re-Transmission output models are also available in addition to the industry standard 4 -20mA or 0 - 10V DC output. Optional RS 485 (2 wire ) output also provided for PC communication with PC Interface software & also with MODBUS RTU protocol.
