The Sentry is a universal voltage trip amplifier for industrial monitoring and alarm applications.
The Sentry is a universal voltage trip amplifier for industrial monitoring and alarm applications. It accepts 7 signal input types (Potentiometer, V, Tc, mA, Freq, NTC and RTD) and works with both AC or DC voltage (24-250 V AC or 19.5-250 V DC). This provides in-field flexibility and eliminates the risk of the unit being accidentally blown up by use of an incorrect power supply. The Sentry has 2 relay outputs for alarm or control applications and an optional isolated analogue output, which converts signals to 0-10 V or 4-20 mA for forwarding to a PLC or SCADA systems.
