This dual channel temperature meter can measure and display temperatures from two probes at the same time. It allows the user to monitor the temperature of more spots with limited panel space. This unit works with Pt100 RTD type temperature sensor. It contains two relays that can be programmed to turn on (or off) at specific temperature (range) separately. These relays are versatile and can be used for many different types of applications. For example, each relay can be programmed as process (absolute) alarms. It can be set to turn on when alarm condition meets. It can also be set to a single pulse for a pre-determined time duration, so that it can be turned off by itself automatically. When the relay is set to latch mode that can only be turned off by user intervention, it can be looped into the control output, so that it functions as an over temperature protection mechanism. If the relay is set to turn on when the temperature is not in the alarm zone, it can be used to control other devices for the specific temperature range, such as a circulation pumps.
