UniOP ePALM10 Handheld Human Computer Interface

UniOP ePALM10 Handheld Human Computer Interface

In modern industrial automation, fixed operation panels have been widely used in various types of equipment, but many scenarios require operators to monitor and intervene near the equipment or during the movement of the production line. Exor's ePALM10 handheld HMI was born for this purpose. It combines the powerful features of the UniOP family with the portability of handheld devices, equipped with a graphic display screen, multifunctional keyboard, emergency stop button, enable switch, and multiple communication options, making it an ideal mobile terminal for factory workshops, large machinery, assembly lines, and other occasions. This article is based on the official product manual and provides a comprehensive analysis of the technical features, operating instructions, connection methods, and attachments of ePALM10.

Operation Guide

4.1 Enable switch

The enable switch is an important safety device for handheld HMI, and ePALM10 offers two configurations:

Two independent 2-position switches: Both switches (NO contacts) must be pressed simultaneously to directly connect to the controller.

A 3-digit switch with three positions:

Release (not pressed): Contact disconnected, not enabled.

Press (middle position): The contact is closed, enabling.

Fully press (press to the bottom): the contact opens, emergency stop (panic).

This switch provides two independent NO contacts that are directly connected to the controller.
