9.4.2.2. Temperature Alarms and Alarm Output

The M501-TRS’ controller has two user settable alarm points: High Alarm and Low Alarm. A single SPST alarm output is triggered should the PV rise above the set level of the high alarm point or fall below the level of the low alarm point.

The relay is normally open, and the contact closes in the alarm condition. The relay contacts are isolated (dry) SPST, 220VAC / 30 VDC 1 Amp, resistive load. This alarm output is available via a connector on the rear panel of the M501-TRS.

The M501-TRS temperature controller is programmed to hold off activation of either alarm until after the process value rises above the lower limit for the first time after power up.
