DIB01 and PIB01 are precise TRMS AC/DC over or under current (selectable by DIP-switch) monitoring relays. Direct measuring or through current transformer. Owing to the built-in latch function, the ON-position of the relay output can be maintained. Inhibit function ensures that the relay output remains OFF after the current has returned to normal range.
The DIB01 and PIB01 monitoring relays provide true RMS AC/DC over‑ or under‑current detection with selectable measuring ranges from 0.1 mA to 10 A. Features include adjustable hysteresis, delay functions, programmable latching or inhibit modes, and an 8 A SPDT output relay.
The relays are designed for DIN‑rail mounting (DIB01) or plug‑in modules (PIB01) with supply options of 24 VDC, 48 VDC, 24/48 VAC, or 115/230 VAC. Detailed specifications cover input ranges, output ratings, mechanical and electrical life, and environmental ratings such as IP20 and temperature limits.
| Measuring range | 0.1 mA to 10 A AC/DC |
|---|---|
| Output relay | 8 A SPDT, N.D. or N.E. selectable |
| Power supply options | 24 VDC, 48 VDC, 24/48 VAC, 115/230 VAC |
