Alarm annunciator SELCO A/S

The Digital Process Alarm Monitor, M4200 is capable of surveying the state of up to 8 potential free contacts by the total of 8 inputs. Each input controls a bright red LED and can be combined with up to four open collector outputs.

The inputs can be used to monitor both normally open (NO) and normally closed (NC) contacts. Each contact can be sourced to a positive or negative reference. Three built-in relays provide audible alarm through control of an external siren or other equipment.
