Product Details
MS7922 thermocouple input signal isolator
1、 Characteristics
2 in 2 out
·Suitable for thermocouple inputs such as K, E, S, B, etc
·Adjustable angle range setting input type and range
·Isolated output 4-20mA or 1-5V
2、 Technical specifications
|
·Accept thermocouple or millivolt signal input, and output standard DC signal to control system or other instruments through isolated transmission. ·It is an intelligent thermocouple input temperature transmitter that can be programmed with a PC and control software to set the input type and range. And it can verify the zero point and full degree of the output signal. Dual channel, two inputs, two outputs. DC power supply mode, with one input and one output of the power supply and magnetic and electrical isolation between each channel. ·Standard 35mm DIN rail card installation. Pull out plug terminals with spring compression connection. It can be used in conjunction with unit combination instruments, DCS, PLC and other systems, and is widely used in various temperature detection and control systems in industrial production processes. ● Input (Can be set through PC and software programming) Thermocouple: K; E; S;B; R;T; N;W; J and others Temperature range: Depending on the type of sensor connected (see range table) Optional millivolt signal input: -10~+100mV Range * * * Small millivolt range: 5mV ● Output Output signal: 4~20mA, 1~5V, or other specified signals Load resistance: ≤ 550 Ω when outputting 4-20mA (factory default) When outputting 1-5V, ≥ 100K Ω |
● Power supply Power supply voltage range: 20~30VDC Rated supply voltage: 24VDC Current consumption (when powered by 24VDC):<60mA ● Comprehensive parameters Standard accuracy: ± 0.1% (see thermocouple type, range, and measurement error table) Cold end temperature error: ± 1 ℃ Cold end temperature compensation range: -15~+75 ℃ (compensation resistor installed inside the instrument) Temperature drift: Basic error/10 ℃ Response time:<10ms Compensation temperature stabilization time:<1min Isolation capability: 2.5KV, 1min.50Hz between input output power supply Insulation resistance: ≥ 100M Ω/500VDC between input output power supply Working environment temperature: -20~+60 ℃ Storage environment temperature: -40~+80 ℃ Shell material/protection level: PC (polycarbonate) material/IP20 Dimensions: 16x116x110 (mm) |
