to 20mA. Such transducers are available to measure tank and well levels, extreme temperatures, air pres-
sure, water pressure, flow, voltage, current, rotational speed, etc. Contact our technical support depart-
ment for assistance regarding your monitoring requirements. Follow the wiring diagrams below for

The WEB600 includes an SPST relay output that can be used to turn on a light, siren, or other device
whenever an alarm occurs. The output is a normally open dry contact that can be used for low voltage
switching. The relay is rated for up to 30VAC/VDC 1 Amp. A sample wiring diagram is shown below:
