INPUT SPECIFICATIONS

■ DC Current: Input resistor incoporated

(If not specified, the input range is 4 – 20 mA DC.)

Input range: 0 – 50 mA DC

Minimum span: 2 mA

Offset: Lower range can be any specific value within the

input range provided that the minimum span is maintained.

■ DC Voltage

•Code S1 (narrow spans)

Input range: -1000 – +1000 mV DC

Minimum span: 100 mV

•Code S2 (wide spans)

Input range: -10 – +10 V DC

Minimum span: 1 V

Offset: Lower range can be any specific value within the

input range provided that the minimum span is maintained.

If not specified, the input range is shown below.

S1: 0 – 100 mV DC

S2: 1 – 5 V DC

Alarm Trip Operation Terminal No. in parentheses

Trip operation in power failure: Terminals 3 – 4 turn ON.

INSTALLATION

Power consumption: Approx. 0.5 W

Operating temperature: -20 to +55°C (-4 to +131°F)

Operating humidity: 30 to 90 %RH (non-condensing)

Mounting: Installation Base (model: M6NBS) or DIN rail

Weight: 65 g (2.3 oz)

PERFORMANCE in percentage of span

Setpoint accuracy (trip point accuracy) : ±0.05 %

Setpoint accuracy is inversely proportional to the input

span.

[Example] Input type 0 – 50 mA, Input range 4 – 20 mA

Max. Input Range (50 mA) ÷ Span (16 mA) × 0.05 %

= ±0.16 %

Temp. coefficient: ±0.01 %/°C (±0.006 %/°F) of max. span

Response time: ≤ 0.2 sec. (0 – 100 % at 90 % setpoint)

Line voltage effect: ±0.1 % over voltage range

Insulation resistance: ≥ 100 MΩ with 500 V DC

Dielectric strength: 2000 V AC @1 minute (input to output

to power to ground)
