The versatile Multi-Input Field Unit can accept
conditioned signals or raw sensor inputs. Using the 22
point offset curve, transducer outputs can be converted
into meaningful engineering units with non-linear curves
that are user programmable.

Multiple Input Field Unit Description
The Multi-Input Field Unit is ideal for adding wireless
capabilities to existing or new wired measurement
sensors such as radar tank gauges, flow meters,
chemical analyzers, or any other device that has voltage
or current outputs. The Multi-Input Field Unit is available
in current (4-20 mA), voltage (0-10 V), or millivolt
(0-1000mV) versions, each accepting up to two analog
inputs. Each model also includes two discrete contact
closure inputs (for simple apparatus). A variety of
packages are also available to fit the field environment
ranging from NEMA 4 or 4X to NEMA 7 Explosion Proof
for integration to field instruments not rated intrinsically
safe. The XP housing can also be used to provide field 24
VDC power (if available) in lieu of standard battery power.
The Field Unit is an integrated input module, signal
conditioner and RF transceiver with self-contained power
operating in the 902 MHz to 928 MHz ISM license-free
band. Rated intrinsically
safe, it is approved for use in all hazardous areas.
Optional output switches can also be provided to
perform on/off control in the field based on
programmable input set point. Output switch option for
ordinary area classification only.
• ± 0.1 % of Full-scale reading at reference conditions
• Ambient Temperature Effect = ± 0.01% of reading per
°C
Sampling and Transmission Characteristics
The Multi-Input Field Unit samples analog signals (4-20
mA or 0-10 V) at regular intervals. The data may then be
transmitted to the Base Radio for centralized monitoring
and data acquisition.
The user specifies how frequently the process is
monitored and how often data is transmitted.
• Input 1 and Input 2– user designates low rate and high
rate conditions
• Sampling rate– user selectable from 1 to 60 seconds
(low rate) and from 1 to 30 seconds (high rate)
• Transmission rate– user selectable from 1 second to 60
seconds (low and high rate)
The Wireless Instrumentation Manager can be used for
real-time monitoring of the process information. The user
can set thresholds to represent “alarm” or abnormal
conditions.

sight; 500’ to 1000’ typical range with obstructions The
RF module in each Field Unit is individually tested and
calibrated over the full temperature range to ensure
reliable wireless operation
Self-Diagnostics
Low battery alarm – indicates the need to replace the
battery (approximately one month warning)
Contains extensive self-checking software and hardware
that continuously monitors the operation. Any sensor or
device parameter out of spec is identified and reported
