Tosilon RTD Resistance Signal Type Intrinsic Safety Barrier (ATEX, FCC, Ex Approved)
Design and Manufacturing according to ATEX, UL Standard
Introduction
This type of isolated safety barrier transmits RTD resistance signals from hazardous area to safe area by isolating transmitting current or voltage or resistance signals in a circuit or two isolated circuits, and it may also be connected in a connection network in safe area via communication ports. The input, output, and the power supply are galvanically isolated from each other. It is an intelligent product with online self-diagnosis function. Customer may set the type and the range of the input or the output signals with a specific handheld programmer we provide.
Main Parameters (For Details, please contact Tosilon, thank you)
Explosive-proof grade: [Ex ia] IIC
Permissible input signal from hazardous area:
2/3-wire RTD resistance:Pt100, Cu100, Cu50, BA2, BA1 etc.
Linear resistance:40~400Ω
Signal type and range can be specified at your order and may also be programmed by user.
Output signal to safe area:
DC current:0~10mA, 4~20mA, 0~20mA
DC voltage:0~5V, 1~5V, 0~10V
1:1 resistance repeating
Signal type and range can be specified at your order and may also be programmed by user.
Transmitting accuracy for RTD (at 25ºC±2ºC, without temperature compensation):
If measurable range <100ºC: ±0.1ºC;
If measurable range ≥100ºC: ±0.1%FS
For linear resistance:
Accuracy reduces in proportion to Im. e.g.:
1 mA ≤Im≤5 mA: Rm < 0.1
0.5mA ≤Im < 1 mA: Rm < 0.15
0.2mA ≤Im<0.5 mA: Rm < 0.45
Rise time: ≤ 2 s (bounce from 10%~90%)
Influence of ambient temperature: <30ppm/ºC
Lead resistance: ≤ 20 Ω per lead
Output load capacity:
DC current:0~10mA: 0~700 Ω;4~20mA: 0~350 Ω
DC voltage: 0(1) ~ 5V: ≥ 1 MΩ; 0~10V: ≥ 2 MΩ
Parameters certified by China National Quality Supervision and Test Centre for Explosion Protected Electrical Products (CQST):
Um=250 V AC/DC
