6150-XX-UM ProDAQ 6150 Isolated Thermocouple Signal Conditioning Unit User Manual

1. Introduction

1.1. Overview

The ProDAQ 6150 is a 1U high rack-mountable LXI instrument. The ProDAQ 6150 is available in

three versions (16-, 32-, and 48 channel) and provides high precision measuring of thermocouple

sensors. Each channel is identical and is isolated from every other channel and from chassis

ground for common-mode working voltages up to 350VRMS.

Figure 1 - ProDAQ 6150-AC Isolated Precision Thermocouple LXI Instrument

Every channel has a universal thermocouple connector allowing any type of thermocouple to be

connected. Thermocouples can be mixed in any fashion. The software interface provides for all

common thermocouple types J, E, N, K, T, R, S and B as well as custom types via a programmable

conversion. Each channel has individual cold-junction compensation (CJC) located right at the

thermocouple connector inputs. Open-thermocouple detection (OTD) is provided per channel, the

occurrence of which is signaled both in software and by a front panel LED.

The ProDAQ6150 uses one 24-bit Sigma-Delta ADCs per channel to provide the highest possible

measurement accuracy and simultaneous sampling. The sampling rate can be varied from 5 S/s to

1000 S/s. At sample rates of 20 S/s or lower, special digital filters still allow to reject both 50Hz and

60Hz frequencies, thus eliminating the effects of power line noise.

1.2. Product Features

1.2.1. Channel Isolation

The ProDAQ 6150 provides complete isolation both from channel to channel and from channel to

ground. This allows the operator to connect thermocouple sensors with high Common Mode (CM)

voltages without affecting other channels or the measurement accuracy. The ProDAQ 6510 has

been tested to IEC 61010-1 Ed 3.0 (2010-06) and IEC 61010-2-030 Ed 1.0 (2010-06). It has been

type tested to Class II with a working common mode voltage of up to 350VRMS.

Having isolation per channel also reduces the effects of offset and noise due to ground loops on

measurement accuracy. This can occur when both the sensor and the measuring equipment is

grounded. In such cases the difference is GND potential can cause current loops which manifest as

voltage differences in the grounds of the two devices. Even a few microvolt of offset can affect the

accuracy of the measurement. Having a floating thermocouple measurement eliminates this

potential source of error.

1.2.2. Mixing of TC Types

Each channel is independently configurable for the standard thermocouple types J, E, N, K, T, R, S

and B as well as for custom types. Each channel permits up to two custom types to be stored.

Hence, a 48-channel unit allows for 96 custom thermocouples to be used, if dedicated to particular

channels. Up to 16 coefficients can be programmed for each custom thermocouple.

1.2.3. Thermocouple Measurement Range

The ProDAQ 6150 allows for a wide range of precision thermocouple measurements to be

performed, as shown in Table 1-1.

Table 1-1: Measurement Range for Standard Thermocouples

1.2.4. Sigma Delta filtering and Rejection of 50/60Hz

At sample rates of 20 Samples/sec or less both 50Hz and 60Hz interference are rejected by a

special filter in the ADC. For higher sample rates, the external circuitry of the channel performs the

rejection. Hence, power line noise, a potential source of error, is rejected.

1.2.5. Simultaneous Sampling

The ProDAQ 6150 uses independent Sigma-Delta ADCs per channel to provide true simultaneous

sampling.

1.2.6. Wide Range of Sampling Rates

The ProDAQ 6150 allows choosing freely any sample rate between 1 Sample/second up to 1000

Samples/second with a resolution of 1 S/s. Lower sample rates can be achieved by using the

trigger scheme implemented.

1.2.7. Open Thermocouple Detection

Each channel of the ProDAQ 6150 contains an independent OTD circuit, which may be switched

ON or OFF as required. When switched on, a broken wire is indicated both optically via a front-

panel LED and programmatically through error status codes and events.

1.2.8. Cold Junction Compensation

Each channel of the ProDAQ 6150 contains its own Cold Junction Compensation (CJC) circuit. The

measurement of the CJC is directly at the copper terminals of the front panel connector, i.e. directly

6150-XX-UM ProDAQ 6150 Isolated Thermocouple Signal Conditioning Unit User Manual

at the cold junction. In this way the highest possible accuracy is achieved as changes in the cold

junction temperature are immediately sensed. A precision interchangeable thermistor, configured in

a ratiometric manner, is used to sense the temperature.

1.2.9. Industry Standard Input Connectors

The ProDAQ 6150 uses industry standard uncompensated mini-TC Cu-Cu thermocouple input

connectors. This connector provides a solid and reliable connection. Different thermocouple types

can be mixed throughout the unit without hardware modification, since the connector is not

thermocouple-type specific.

1.2.10. Isolated Digital I/O

Each version of the ProDAQ 6150 features 4 isolated digital I/O lines on the rear panel, 2 input and

2 output. These are generic lines which may be used for generating and/or receiving digital signals

as for example trigger events.

1.2.11. LXI Trigger Bus

Optional the ProDAQ 6150 can feature the LXI Hardware trigger bus, allowing the device to share

trigger signals with all compatible LXI devices.

1.2.12. Triggering

An extended trigger scheme allows hardware trigger received via the isolated trigger lines or the

LXI trigger bus as well as software triggers like LXI events to control the acquisition process.

1.2.13. Scalable Technology

A single ProDAQ 6150 can contain either 16, 32 or 48 channels. However, multiple units can easily

be synchronized using the IEEE1588 clock synchronization via Ethernet or the optional LXI trigger

bus, providing any amount of simultaneous sampled channels required.

1.2.14. Data storage

The ProDAQ 6150 features a RAM disk of 64MB to store data acquired independently of the host

controlling the device. Optional SSD hard drives can be installed to permanently store data on the

device, allowing a fully independent stand-alone mode. Data acquisition to both storage devices as

well as the data retrieval can be done via the web interface.
