⚠️ Hardware Sub-Model Selection Required
The format of the Analog Input (AI) is hardware dependent. You cannot switch between 4-20mA or 0-5V or 0-10V with software. Please ensure you have selected the correct AI sub-model from the dropdown before adding to cart.
Product Overview
Valtoris 8CH-IO-LTE is an industrial grade Cellular Remote I/O Controller for off-grid telemetry. It has 8 Digital Inputs, 8 Relay Outputs and 8 Analog Inputs natively integrated along with a dedicated RS485 serial gateway. It eliminates the need for expensive cabling and micro-PLCs by sending data over 4G LTE CAT1 networks using MQTT or Modbus TCP.
Quick Specs & Capabilities
