VMU-M EM is a VMU-C EM system accessory module that controls accessory modules via local bus so as to manage analog variables (VMU-P EM) and digital inputs/outputs (VMU-O EM). It communicates with the main VMU- C EM module via RS485 port.
Features
• Local data and event recording
• Local alarm management
• Accessory modules management: up to one VMU-P EM with analog inputs and up to three VMU-O EM with digital inputs/outputs.
• Two direct inputs (digital or temperature)
• Communication ports: RS485 Modbus RTU and local bus
• 1-DIN size
Functions
• Record VMU-P EM and VMU-O EM accessory modules data
• Transmit accessory module data via serial communication to the main VMU-C EM module
• Read data from the one digital input or two temperature inputs for local display and alarm threshold management
• Local display of real time variables
