7100 Programmable transmitter to RS-485 bus

Product catalog summary

Overview: The document provides detailed technical specifications and operational guidelines for the Nokeval Programmable Transmitter 7100, which is designed to handle various temperature and process signal inputs.

Specifications:

Input Types: Supports thermocouples (types B, C, D, E, G, J, K, L, N, R, S, T), RTDs (Pt100, Pt500, Pt1000, Ni100, Ni1000), process inputs (0..20mA, 4..20mA, -20..+20mA, 0..5V, 0..10V, -10..+10V), IR-thermocouples, and mV inputs (-100..+100mV).
Output: RS485 output with a maximum distance of 1000 meters and a baud rate ranging from 300 to 19200 bps.
Power Supply: 24VDC with a power consumption of up to 40mA.
Isolation: Galvanic isolation between input, output, and power supply.

Technical Details:

Thermocouples: Various ranges and linearity specifications are provided for each type, with calibration accuracy of less than 0.1% of the maximum span.
RTDs: Range from -200 to +700°C for Pt100 and Pt500, with a calibration accuracy of 0.05% of span or 0.1°C.
Process Inputs: High accuracy and linearity with input impedance specifications for current and voltage inputs.
IR Sensors: Specific ranges for Exergen 140F-K and 440F-K models with emissivity correction options.

Construction and Configuration:

The transmitter is versatile, supporting digital outputs for RS485 serial ports, suitable for applications requiring digital input like PC serial ports or programmable logic controllers.
Configuration can be done via a PC or a handheld programmer (model 6790), with options for factory configuration.
Supports up to 32 transmitters on the same serial bus.

Applications: Ideal for data acquisition systems, compatible with Nokeval's data collection software WinX, and can be integrated with RS485/RS232 converters for broader compatibility.

Ordering Information: Includes optional accessories like cables for transmitter/PC connection, configuration software MekuWin, and handheld programmer 6790.
