monitoring relay

Introduction DUB71 is a precise TRMS AC/DC over or under voltage (selectable by DIPswitch) monitoring relay. Owing to the built-in latch function, the ON-position of the relay output can be maintained. Inhibit function can be used to avoid relay operation when not desired (maintenance, transitions). The LED's indicate the state of the alarm and the output relay. 35.5 mm wide housing suitable both for back and front panel mounting. • TRMS AC/DC over or under voltage monitoring

Introduction 817S-PTC-48, 817S-PTC-115 and 817S-PTC-230 are precise thermistor monitoring relays. They can be used to monitor the temperature of the coils of a motor with built-in PTC's. The alarm status of the relay can be reset by an internal button. The test button allows the simulation of the fault condition. The red LED indicates the alarm status. • Motor temperature monitoring relay • Measuring ranges: PTC according to EN 44081 • Remote and local alarm reset • Output: 8

Introduction 814S-W3-480V-10A,814S-W3-690V-10A are precise TRMS active power monitoring relays for 3-phase balanced systems. They can be used for monitoring the actual load of asynchronous motors and other symmetrical loads, as well as to see if the power flows in the correct direction. Start/stop input allows to use a manual switch to start and stop the system, without the need of an auxiliary device. The advantage of using the latch function is that the alarm status can be
