Current Relay 1 Phase 12-48V ac/dc
Art: MRI11/UC12-48V
The monitoring relay family MR is developed for the supervision of AC and DC TRMS voltages.
The device is able to measure voltages and currents in 1 and 3-phase systems and determine the best measuring resolution with an automatic range selection. It possesses a permanent self-diagnosis. Therefore it is secured that an alarm will be released in any case of disturbance or failure.
The handling is very easy. Measuring values, user's parameters and the operation status are indicated on a display and can be adjust with the user-friendly service menu (3 keys).
Two outputs with changeover contacts for 6 A, 250 V are available. Both contacts can be switched independently of each other (2 relays). A red LED indicates the alarms.
The devices comply with the DIN standard 43880 and have a mounting width of 35 mm.
