Industrial AI-04RT-00-24VDC Analog Input Module

The ASCON TECNOLOGIC AI-04RT-00-24VDC is a four‑channel analog input module designed for DIN‑rail mounting in CANopen and Modbus RTU networks. It provides four configurable analog input channels that support RTD/PT100/PT1000 sensors and thermocouples (types J, K, L, N, R, S, T), with low‑level signal ranges such as ±50 mV, ±300 mV, and ±1.0 V. The module is powered from a 24 VDC supply and offers three‑way isolation between the analog inputs, logic, and the field bus to help protect the controller from noise and faults. On the bus side, two RJ45 connectors handle CANopen communication, and the unit also supports Modbus RTU, enabling flexible integration with existing automation architectures. Addressing and baud rate are configured via two 16‑position DIP switches (one for Node ID and one for baud rate), while four LEDs provide at‑a‑glance status diagnostics. This AI‑04RT variant belongs to ASCON’s IO‑CB family of analog I/O modules, combining compact form factor with rugged, industrial‑grade performance for applications such as process monitoring, environmental sensing, and multi‑sensor data acquisition in control panels and automation cabinets.
