mm)

Housing material: Flame-resistant resin (gray)

Isolation: Input to output to power

Overrange output: -15 to +115 %

Zero adjustment: -15 to +15 % (front)

Span adjustment: 85 to 115 % (front)

Status indicator LED: Tri-color (green/amber/red) LED;

Blinking patterns indicate operation status of the

transmitter.

PC configurator: Programmable features include:

• I/O type and range, detecting level

• Zero and span adjustments

(max. 101 points, specified within -15 to +115 % for both

input and output)

• Sampling time (0.05 – 100 sec.)

(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;

RS-232-C level
