Monitoring Relays

1-Phase AC/DC Over Current

Types DIA01, PIA01

• 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
