Weidmuller 8528650000 output current loop fed AC current monitoring components WAS/WAZ1 CMA LP. The WAS1 CMA LP 1/5/10A ac can measure 1 Phase 50/60Hz AC currents of up to 10A using the root mean square (RMS) method on the input side. It can also be switched between three ranges. No external power supply is used and the supply is only via the 4 to 20mA current loop on the output side. The input and output circuits are securely isolated with 4kV. The monitoring components come in a 17.5mm wide WAVEBOX housing. This device can be used in many process automation applications because it is not dependent on an external power supply. It features add-on housing for TS35 rail mounting and the input and output circuits have 6kV of electrical isolation.
