The DFD420 pulse divider and transmitter has two basic functions: Pulse input to pulse output converter, by means of a programmable divider factor. Programmable frequency to current converter. It adapts to the most Nixon Flowmeters, series COVOL and TM flowmeters. Likewise, it can be connected to other sensors whose output signal is a potential free contact or a pickup.
Applications
Automated process control in any industry with flow rate or volume control for interfacing with PLC and other instruments. Interface with PLC inputs. Interface with analog indicators or alarms.
Benefits
