NewPWR NP Series Intelligent Programmable Signal Isolators Safety Barriers

NP Series Intelligent Programmable Signal Isolators & Safety Barriers (Current Mainstream)

This is the core and flagship product line under the NewPWR brand, representing the latest technology.

Features:

Intelligent Programmability: Easily configure input/output types and ranges via a handheld programmer or software, eliminating the need for DIP switches. A single module adapts to various signals (thermocouples, RTDs, voltage, current, etc.).

High Precision: Typically achieves accuracy of 0.1% or higher.

LCD Display: Some high-end models feature an LCD screen for real-time monitoring of input/output values and status, simplifying debugging and maintenance.

High Reliability: Robust anti-interference capability and electrical isolation performance.

Common Model Examples: Specific models of the NP series.

NewPWR NP Series Model Numbering Rules Explained

The model numbers of the NP series consist of a string of letters and数字 codes, where each segment represents specific product attributes. A general structure is as follows:

NP - [Channel Number][Function Code] - [Input Type][Output Type] - [Auxiliary Function] - [Power Option]

Breakdown of Each Segment:

Channel Number (Channels)

D: Single-channel

S: Dual-channel

Function Code

90: Universal signal isolator (basic function)

91: Signal isolator with power distribution (supplies +24V to two-wire transmitters)

92: Signal isolator (one input, two outputs)

93: Signal alarm isolator (includes alarm value setting and output)

**: Other combinations may indicate specific functions (e.g., power isolation).

Input Type

A: Current signal (e.g., 4-20mA, 0-20mA)

V: Voltage signal (e.g., 0-5V, 0-10V, 1-5V)

T: Thermocouple

R: RTD (e.g., Pt100)

M: Millivolt signal (mV)

W: Potentiometer/resistance signal

Output Type

A: Analog current output (e.g., 4-20mA)

V: Analog voltage output (e.g., 0-5V, 0-10V, 1-5V)

Auxiliary Function

D: With LCD display (key feature of the NP series)

P: Other special functions (refer to the manual).

Power Option

□: Typically indicates power range (e.g., 24 for DC 24V supply) or wide-range AC/DC power support.

Typical Model Examples of NP Series Intelligent Programmable Signal Isolators & Safety Barriers

NP-D90-A-A-D-24

NP: NewPWR brand

D: Single-channel

90: Universal signal isolator

A: Current input (e.g., 4-20mA)

A: Current output (e.g., 4-20mA)

D: With LCD display

24: DC 24V power supply

Description: A one-in-one-out current isolator. Isolates and transmits one 4-20mA input signal to one 4-20mA output signal, with display. This is the most basic model.

NP-D91-A-A-D-24

Differs from Model 1 only in the function code 91.

Description: A current isolator with power distribution. In addition to the functions of Model 1, it provides +24V power to two-wire transmitters connected to the input.

NP-D90-R-A-D-24

R: RTD input

A: Current output

Description: An RTD isolation transmitter. Converts RTD signals (e.g., Pt100) into an isolated 4-20mA current output, with display.

NP-D90-T-A-D-24

T: Thermocouple input

Description: A thermocouple isolation transmitter. Converts thermocouple signals (e.g., type K) into an isolated 4-20mA current output, with display.

NP-S92-A-A-D-24

S: Dual-channel

92: One input, two outputs

Description: A one-in-two-out current isolation distributor. Isolates one 4-20mA input signal and distributes it into two independent 4-20mA output signals, with display.
