Sign Discrete Input Interface

The Discrete Input Interface accepts inputs from photoelectric eyes, limit switches, proximity sensors, PLC I/O blocks, relays, push buttons contact closures or any discrete binary, or up/down counting device or sensor. The Discrete Input Interface can be configured to accept inputs in several formats including Discrete, BCD or Binary formats. It can also be configured as a counter. The discrete, binary and BCD inputs trigger change-of-status pre-programmed messages to run on LED marquees such as "Warning: Conveyor Stopped."

The Discrete Input Interface allows you to trigger messages on any display simply and economically!

The up/down counter sends counts which can be displayed on the marquee alone or incorporated into pre-programmed messages such as "Parts Count=1237."

Users create and download custom messages into marquees using the handheld remote or Messaging Software.

The Discrete Input Interface then triggers the appropriate message when the corresponding input on the Discrete Input Interface is closed.

Features

• Easy connectivity to switches, contacts, photo eyes, proximity sensors, relays, PLC I/O blocks, etc.

• Simple interfacing to ALPHA displays via a RS485 multidrop network.

• Configurations for discrete, binary (parallel) and up/down counting and BCD standard options, field adjustable.

• Inputs with 24 Volt DC sink or source capabilities.

• Quick message creation in the display corresponding to the appropriate contacts via the handheld remote or Messaging Software.

•The ALPHA Discrete Input Interface connects to as many as 32 contacts in blocks of 8 inputs. The interface simply mounts on a standard 35mm DIN rail and is easily connected to power, contacts and RS485 serial communications to the marquee
