M3LV SIGNAL TRANSMITTER
(field- and PC-configurable)

Functions & Features
• Accepts a DC mV, V or mA input and provides
an isolated DC signal
• Easy ‘One-Step Cal’ calibration using the front three control buttons without needing a PC; PC software is also usable.
• Both input and output type and range are configurable
• Front control button function can be locked
Typical Applications
• Signal conversion between control room and field instrumentation with isolation
• Ideal for use as a fast solution, multifunctional spare part

Configuration
PC Configurator: (Model: M3LVCFG) via Windows PC connected to th front jack.
  Programmable features include:
• I/O type and range
• Zero and span adjustments
• User’s linearization table setting
(max. 101 points, specified within -15 to +115 % for both input and output)
(Refer to the instruction manual)
‘One-Step Cal’ calibration: With I/O type and the full-scale range configured via the internal DIP switches, precise 0 % and 100 % ranges are calibrated via the front control buttons with a help of LED. Also I/O calibration and fine adjustment are available with a PC.
Configurator connection: 2.5 dia. miniature jack;

PERFORMANCE
Accuracy: Input Accuracy + Output Accuracy
Input accuracy: (% of input range)
(Inversely proportional to the span.)
-1000 – +1000 mV : ±0.01 (%)
-10 – +10 V : ±0.01
0 – 20 mA : ±0.02
Output accuracy: ±0.04 % of output range
(Inversely proportional to the span.)
Temp. coefficient: ±0.015 %/°C (±0.008 %/°F) of max. span
Response time: ≤ 0.5 sec. (0 – 90 %)
Line voltage effect: ±0.1 % over voltage range
Insulation resistance: ≥ 100 MΩ with 500 V DC
Dielectric strength: 1500 V AC @ 1 minute
(input to output or power to ground)
500 V AC @ 1 minute (output to power)

CALCULATION EXAMPLES OF OVERALL ACCURACY
[Example] Input Signal 1 – 5 V, Output Signal 1 – 5 V
Max. Input Range (20 V) ÷ Span (4 V) × 0.01 % +
Max. Output Range (20 V) ÷ Span (4 V) × 0.04 % = 0.25 %
