A&D AD-4406-03 (AD440603) RS-422/485 Interface with 3 Relay Outputs for AD-4406A Indicator

Description

The A&D AD-4406-03 (AD440603) adds an RS-422/485 serial interface and three relay outputs to the AD-4406A compact indicator. RS-422/485 carries weight data over much longer cable runs than RS-232C and lets several devices share one line, and the relays switch lights, buzzers, gates or feeders from the indicator’s comparator results.

Tips

Choose the interface by the distance and the device at the other end: AD-4406-04 for a plain RS-232C link, AD-4406-03 when you need RS-422/485 or relay control.

FAQ

Can I use it with an RS-232C option at the same time?

No. Only one interface option can be fitted to the AD-4406A.

What are the relays used for?

The three relay outputs follow the comparator results, so they can drive stack lights, buzzers or simple fill and reject control.
