The DIS-323AL and DIS-323SS are flameproof field mounting loop powered indicators that only introduce a 2.3V drop, making them suitable for inclusion in almost any 4-20mA loop. The two instruments are electrically identical but have different enclosure materials. The DIS-323AL is housed in an epoxy painted aluminium enclosure and the DIS-323SS in a 316 stainless steel enclosure. Both provide IP66 and NEMA Type 4X protection.

Configuration and calibration of the indicators is performed via simple Windows compatible software running on a PC connected to the instrument via a temporary communications cable. The view button on the front of the indicator adjacent to the terminals provides a rapid check of loop function and instrument calibration with no risk of the calibration being accidentally changed.

Both instruments are suitable for use in zone 1 and 2 hazardous areas, and units of measurement can be displayed in up to five digits, entered via the configuration software.
