2. Description
The MCR-S-…-DCI, active current transducers convert direct, alternating and distorted currents from 0…
0.2 A to 0…11 A (MCR-S-1-5-...-DCI) and from 0…9.5 A to 0…55 A (MCR-S-10-50-…-DCI) to analog
standard signals.
On the output side, the analog standard signals of 0(4)…20 mA, 0(2)…10 V, ±10 V, 0(1)…5 V, ±5 V with
simple (e.g. 0…10 V) and inverse (e.g. 10…0 V) signal flow direction can be used.
An option for the current transducers with threshold output (MCR-S-…-SW-DCI) is a PNP transistor swit-
ching output (80 mA) and a relay switching output (2 A).
2.1. Method of operation
Connecting to the input terminal blocks (MCR-S-1-5-…-DCI), or passing the live conductor through the
current transducer (MCR-S-10-50-…-DCI) evokes a magnetic flow in the annular strip-wound core.
The density of magnetic flow is measured with the aid of a Hall sensor and converted proportionally from
the input current to a voltage (Hall voltage). A downstream true r.m.s. converter enables DC, AC and
distorted currents to be measured. The signal is amplified for further conditioning and made available at
the output as a proportional analog signal.
2.2. Versions
This package insert is valid for the following types of current transducers:
