Description

OP04 – Graphic terminal

OP04 is small industrial graphical terminal for data displaying and editation. Display and editation functions including communication protocol are implemented by software equipment.

Terminal is equipped with 2 serial communication interfaces (RS232 and RS485) which can be used simultaneously.

Membrane keypad is rugged with 6 buttons and with tactile feedback.

Terminal is designed for mounting to device panel.
