Product Details

Thermal resistance input signal isolator

1、 Characteristics

MS7082(1入1出)、MS7920(1入2出 )

·Suitable for thermal resistors such as Pt100 and Cu50

·Isolation output 4-20mA or 1-5V

2、 Technical specifications

·Suitable for thermal resistance signal input, after isolation, converted into standard DC signal with circular fixed range output to the control system or other instruments.

·Single channel, one input, one output. DC power supply mode, with isolation between the power supply input and output.

4、 Dimensions and installation diagram
● Installation
1.35mm standard DIN rail card installation. Please pay attention to the stability and firmness of the card position during installation.
2. Install vertically as much as possible to facilitate heat dissipation inside the instrument.
● Typical applications
1. Used to provide distribution voltage to on-site transmitters and isolate and convert input signals.
2. Devices connected to the site: Active electrical signals from two-wire or three wire non smart transmitters.
3. Connect to the control system (or other unit combination instruments): The AI card of each DCS/PLC receives current or voltage signals.

● External dimensions
Width (thickness) x height x depth=16 x 116 x 110 (mm)
