Monitoring Relays 1-Phase AC/DCOver Current Types DIA01, PIA01 DIA01PIA01 • AC/DC over current monitoring relay • Current measured through internal shunt • Measuring range 0.5 to 5 A AC/DC • Adjustable current limit on relative scale • Adjustable hysteresis • Programmable latching at set level • Output: 8 A SPDT relay normally de-energized • For mounting on DIN-rail in accordance with DIN/EN 50 022 (DIA01) or plug-in module (PIA01) • 22.5 mm Euronorm housing (DIA01) or 36 mm plug-in module (PIA01) • LED indication for relay and power supply ON • Galvanically separated power supply Product Description Ordering Key DIA 01 C B23 5A DIA01 and PIA01 are precise AC/DC over current monitor- ingrelays. Directmeasuring or through current transformer. Owing to the built-in latch function, the ON-position of the relay output can be maintained. The redLED indicatesthe relay status. Through the built-in shunt it is possible to monitor loads up to 5 A AC/DC.
