CEC021 - 15 Message Programmable LCD Display (20x4)

15 message, programmable LCD display, with 4 lines of 20 characters. One default message and up to 14 other messages are programmable using an onboard keyboard or a second pre-programmed board. 

Any of the 14 remaining pre-programmed messages can be displayed by closing the respective input contacts.

Functions include:

• default message - displayed when no one of the 14 pre-recorded messages is selected
• hierarchical or rotary display mode - when several messages are selected at the same time hierarchical mode displays the most important message; rotary mode displays all messages
• external message activation using any 'make' contact e.g. switches, relays, open collector outputs or simply push buttons
• single or dual line messages
• standard or large size characters
• serial connector - this allows you to dump the pre-programmed messages onto a second module.

A data transfer cable is also available, which allows for messages to be sent from one module to another, therefore avoiding manual programming.

The module includes protection against inverse polarity, indicator LED and screw terminal connections.
