EM3xx & EM322AC
Multi-input modules
EM322AC module: two inputs and two relay outputs for 230 Vac loads, with supervision
The EM322AC module connects to the loop and provides two supervised inputs and two relay outputs for controlling 230 Vac-powered loads. Each output can be monitored to detect voltage presence even when the relay is off. Featuring a short-circuit isolator, status LED, and automatic addressing, the module supports DIN rail installation or mounting inside standard electrical boxes. A robust, versatile solution for managing mains-powered devices.
EM3xx modules: multi-input/output and interface for conventional zones
EM3xx series modules provide advanced management of inputs, outputs, and conventional zones within loop-connected systems. Depending on the model, up to four inputs are available, two of which can be configured as conventional zones, powered either by the loop or an external source. The four outputs, also variable by type, can be monitored to control visual-audible signaling devices or used as dry contacts. A modular, flexible solution for comprehensive management of conventional devices and circuits.
