UDM Series μP-based indicators/controllers feature a rugged 1⁄8 DIN housing, rated IP67/NEMA4x. The UDM40's Unique Display Can Be Programmed to Display in One of Three Colors: red, amber or green; or it can be programmed to display in a different color should an alarm setting be eclipsed, i.e. Green: OK, Amber: Caution, Red: Trouble. Indicator's features include min/max recording, data hold, display/input range scaling and password protection. The UDM60 is a universal tachometer and counter with dual display that can simultaneously display two independent variables. Indicators become controllers by inserting one or more of the output cards, listed separately at the bottom of this page. Controllers feature up to four alarms, with adjustable hysteresis, delay and high/low/input fault alarms. All parameter settings are controlled by the front keypad via easy-to-use menu-driven format. 90-260 VAC/VDC supply; other voltages are available. UL recognized, CSA certified, CE compliant.
When a power supply card and multi-range configurable input card are slid into a BD type display, a UDM indicator is the end result. Indicators become controllers by inserting one of the output cards, listed separately at the bottom of this page.
