–
option X/100mA for indirect measurement with special curerent transformers (nominal secondary
current up to 100 mA)
–
optional X/333mV current inputs for split core CTs or flex-probes (RCTs) with nominal output
0.333 V. Aux. supply 5 V for RCT also available.
–
option NOCT measures only voltages, does not have any current inputs. It is possible to use it as a
smart transducer and relay, with memory, to analyse frequency, voltage, harmonics, unbalance and
voltage quality (with PQ module).
one digital input 24V
2x relay or impulse output (option RR, RI or II)
features can be upgraded via external I/O modules (with ModBus Master module)
