Current monitoring module EDMUC540

Chordn EDMUC540 associated with CR1U series solid state relay allows to control and to make a diagnostic with one or more loads (maximum five loads in). It allows to detect open mains, open load or partial load break or a short-circuited SCR. The module monitors continuously the load current by current transformer and compare with a preset current value. The instruction current value (teach current) is validated by the operator with the "TEACH" push button (placed in the front) or with the External teach input (Logic Input). If the load current is lower than -16% of teach current (0.84*Iteach), it means there is a partial load break. Main features Supply power: 8-30Vdc Input control range: 4-32Vdc External teach input range: 4-32Vdc Diagnostic output range: 8-30Vdc Nominal current range: 2-40A Max monitoring loads: 5 Alarm threshold: 0.84*Iteach Diagnostic output mode: PNP/NPN Connection control: Screw Pluggable Current transformer hole diameter: 9mm Conformity: IEC/ EN60947-4-3 Housing Material: PA66
