EpiSensor ZIO-2x Datasheet
Introduction
EpiSensor’s ZIO 4-20mA Sensor is intended to detect the current in a closed loop from a 4-20mA transducer.
These transducers can measure a variety of real world conditions such as wind speed or direction, weights,
volumes and depths. The ZIO reports the data through the wireless sensor network to the Gateway.
The ZIO reports data in terms of the measured milliamp signal. This value needs to be converted externally since
the parameter being measured is not known to the ZIO. This allows a single product to become quite versatile
and measure a variety of different transducers for different properties. The ZIO-20/22 product variants are both
mains powered versions. The available product variants are as follows:
Single channel, mains powered 4-20mA sensor
Dual channel, mains powered 4-20mA sensor
4-20 Milliamp Installation
The 4-20mA signal wires should be fed through the enclosure’s M10 waterproof glands and connected to the
terminal block, as shown in the diagram below, taking note of the positive and negative terminals. There will be
2 terminals used per channel, so the dual-channel version (ZIO-22) would use 4 terminals. The input wires are
connected to IN1 for single channel models, and IN1 and IN2 for dual-channel models.
