4-Channel Machine Vision LED Light Controller

POMEAS PMS-GE244PRT

Constant-current machine vision lighting controller with independent 4-channel control, 256-level brightness adjustment, RS-232 communication and external trigger capability.

Key Features

4 Independent Channels

CH1, CH2, CH3 and CH4 can be controlled independently for flexible multi-light machine vision systems.

256-Level Dimming

Brightness can be adjusted from 0 to 255 through the front-panel buttons or PC software.

RS-232 Control

Built-in RS-232 serial communication enables integration with PCs, industrial computers and automation control systems.

External Trigger

Supports 5–24 V external trigger input with a maximum trigger frequency of 1 kHz and 200 μs response time.
