Electronic Monitoring Relays Measure Current and Voltage
MIDDLETOWN, Pa. - Phoenix Contact has added a new family of Electronic Monitoring Relays for single- and three-phase applications to its extensive line of signal conditioners and converters. The new 22.5mm wide, DIN-rail mountable modules can be used for monitoring currents and voltages in numerous applications. The current monitoring relays are designed for monitoring AC and DC currents ranging from 0 to 100mA, 0 to 1A and 0 to10A. The voltage monitoring relays are available for monitoring single phase AC and DC voltages ranging from 0 to 30V, 0 to 60V and 0 to 500V.
The current and voltage monitoring relays are available in two versions. 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 user 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.
The monitoring relays are easily configured via potentiometers and rotary switches on the front face of the modules. Operational conditions of the monitoring relays are displayed via LEDs for supply power transformer voltage, relay status, fault type and delay times.
