Monitoring relays measure current and voltage
Monitoring RelayElectronic monitoring relay for single- and three-phase applications is 22.5 mm wide. The DIN-rail mountable module can be used for monitoring currents and voltages in numerous applications. The Relays are designed for monitoring AC and DC currents ranging from 0-100 mA, 0-1A and 0-10A, and are available for monitoring single phase AC and DC voltages ranging from 0-30V, 0-60V and 0-500V. The SL version has one function, either undercurrent or undervoltage, with a PDT (single pole double throw) for signal output. The multifunctional FL version provides the flexibility of monitoring undercurrent, overcurrent, and window function, or undervoltage, overvoltage, and window function featuring PDT relays (single pole double throw) for signal output. Operational conditions are displayed via LEDs for supply power transformer voltage, relay status, fault type and delay times.
