IoT gateways, I/O and converters
Twelve models, one protocol platform. Choose by connectivity, tag capacity and feature set — every device integrates the same way.
MAX Series
Advanced dual-network industrial gateways
Our flagship gateways for large, mission-critical deployments. Up to 3000 tags, dual upstream servers and dual-path connectivity (4G + LAN/WiFi) with optional LoRa for the hardest-to-reach field devices.
PRO Series
Secure, server-redundant monitoring
Hardened gateways with SSL/TLS, dual-server publishing and battery-backed operation — built for utilities and process plants where data must never be lost.
PRO 4G Gateway
Secure cellular gateway with SSL, dual servers and battery backup.
PRO Ethernet Gateway
Wired PRO gateway with secure dual-server publishing.
PRO WiFi Gateway
Wireless PRO gateway with SSL and dual-server publishing.
LITE Series
Reliable, cost-effective field gateways
The workhorse range for everyday remote monitoring — up to 1800 tags, optional onboard relay and a choice of 4G, Ethernet or WiFi backhaul at an attractive price point.
LITE 4G Gateway
Cost-effective 4G gateway for everyday remote monitoring.
LITE Ethernet Gateway
Wired LITE gateway for stable in-plant monitoring.
LITE WiFi Gateway
Wireless LITE gateway for fast, cable-free rollout.
IO Cards
Analog & digital field expansion
Modbus RTU I/O modules that turn raw sensors, transmitters and contacts into clean register data any Wiman gateway can read and publish.
WT30i Analog Input Card
Compact analog Modbus I/O for reliable voltage-input monitoring.
WT36i Analog/Digital + Relay Card
Versatile Modbus I/O with analog, digital inputs and relay output.
WT60i High-Capacity I/O Card
High-capacity analog/digital Modbus expansion for complex systems.
Converters
Bridge legacy serial to Ethernet
Drop-in protocol converters that bring serial Modbus RTU equipment onto modern TCP/IP networks — no rewiring of the existing plant.
