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;

Configuration

PC configurator:

Programmable features include:

• Input range and output type and range

• Zero and span adjustments

(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

■ Contact Input: TTL level (5V-CMOS level), open collector

or dry contact (detecting voltage: approx. 5 V, saturation

voltage: ≤ 1 V, sink current: 0.5 mA)

OUTPUT SPECIFICATIONS

■ DC Current

Maximum range: 0 – 20 mA DC

Minimum span: 1 mA

(Add 0.1 % to accuracy with output span 2 mA or less.)

Conformance range: 0 – 20 mA DC

(Negative overrange current below 0 mA is not available.)

Offset: Lower range can be any specific value within the

Minimum span: 0.5 V

Conformance range: -11.5 – +11.5 V DC

(Overrange voltage below -11.5 V is not available.)

Offset: Lower range can be any specific value within the

output range provided that the minimum span is

maintained.

Load resistance: Output drive 10 mA maximum; 5 mA for

negative output
