Product Description

The DZ260 Monitors Overspeed, Underspeed, Direction of Rotation (Forward & Reverse) & Standstill of Incremental Encoders & NAMUR Sensors (HTL, RS422 or TTL).  The Scalable Analog output & three programmable relays each with both NO/NC Contacts along with a Serial RS232 interface for PLC/PC. Can also be used for Closed-Loop control or feedback within a control system.  There is an auxiliary 5Vdc/200mA supply for encoders & sensors.  For the 17-30Vdc power supply use the GDA18-24A 24Vdc/750mA.
