Description
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.
