• RS-485 serial communication interface
The PMD-MXT series microprocessor-based temperature scanners provide continuous monitoring of up to 32 channels of thermocouple or RTD sensors. The large 14 mm tall digit red LED display is easy to read, even at a distance. Rows of LED annunciators warn of specific channel alarm conditions.
The scanner has 2 user-selectable HI/LO, HI/HI, or LO/LO alarm set points, configured through the front panel push buttons. During an alarm condition a front panel LED annunciator is enabled & an internal 2 Amp relay contact output is engaged.
The scanner's display will auto cycle through all input channels at a user determined rate of 0.5~10 seconds per channel.
24 VDC powered. A must have for multi-point thermocouple or RTD temperature monitoring in the Lab, control room, or Dynamometer.
