Limit Alarms

Process limit alarms monitor sensors or process current input signals and trip a relay output if the input exceeds a user-defined hi/lo setpoint limit. Select from AC-, DC, and loop-powered models. Configuration is easy with Windows® software, push-buttons, switches, or pots for settings depending on the series. Other cost-effective alternatives are transmitters with integrated alarms or remote I/O modules for Modbus networks with built-in trips for local alarm functions.
