PLUG-IN ALARMS



SWITCH-SELECTABLE HI/LO TRIP FUNCTION                         

AC AND DC POWER OPTIONS AVAILABLE                

ADJUSTABLE DEADBAND IS STANDARD     

5 AMP, 230VAC RELAY CONTACTS

FULL REPLACEMENT WARRANTY

ALL STANDARD INPUT STYLES  

JH Technology's plug-in process alarm modules monitor standard DC, AC or transducer signals and provide relay contact closure outputs. Their 5 amp, 230Vac contacts may be used to actuate alarms, to turn heaters, valves etc. on and off or to signal events to annunciator, datalogger or programmable logic control (PLC) systems. Plug-and-play socket installation lets you remove and replace alarms without rewiring. These modules often provide low-cost alternatives to other monitoring systems.

Available models accept inputs from most standard transducers as well as low- or high-level voltage and current sources. Computational models also are available. Single and dual trip alarms are offered. Top-accessible switches allow easy selection of HI or LO (or HI-HI, HI-LO, LO-LO) trip function. Adjustable deadband is standard on both single and dual trip models. Red/green alarm status LEDs are visible through the tops of the units. AC and DC power options are available.
