DM308 20-CH Actuator / General Purpose Switch

The DM308 20-Ch Actuator / General Purpose Switch (for the DAQ3120) is a dedicated switch module featuring 20 independent single-pole double-throw (SPDT) relays. Each relay is equipped with Normally-Open, Normally-Closed, and Common contacts. This provides users with considerable flexibility in the connection and control of DUTs. Typical applications for this module include power cycling of DUTs, management of indicator and status lights, and activation of external power relays and solenoid valves. This module is rated to handle voltages up to 300 V and currents up to 1 A, with a maximum switching power capacity of 50 W.

Product Features

20 SPDT (Form C) latching relays
Versatile contact configuration with Normally Open (NO) and Normally Closed (NC) contacts
300 V and 1 A contacts for actuation and control

DM307 Multi-Function Module

The DM307 Multi-Function Module (for the DAQ3120) enhances the system’s functionality by offering a combination of digital and analogue control capabilities. It is equipped with two 8-bit digital input/output ports, enabling the control of external devices and the reading of digital signals. Furthermore, it incorporates a totalizer that can count pulses from devices at a frequency of up to 100 kHz. It also provides two analogue output (DAC) channels to generate programmable voltage or current outputs. The module continuously monitors alarm thresholds for both digital inputs and totalizer inputs, logging alarm conditions even when not actively scanning. Additionally, sense channels are included to monitor current or voltage.

Product Features

16 bits of digital input and output
100 kHz totalizer input
±12 V analogue outputs or ±24 mA outputs

DM309 High Voltage and Current Multiplexer

The DM309 8-CH High Voltage Multiplexer with 2 Current Channels increases the maximum measurable voltage from 300 to 600 VDC or 400 Vrms. The 2 additional current channels handle DC and AC measurements up to 2 A without the need of external shunts. For added protection, each current channel connects to a fuse conveniently located within the module. This module supports thermocouple measurements as well, provided there is an external cold junction reference available.

Product Features

Scanning speed up to 60 channels per second
600 VDC or 400 Vrms maximum input
2-wire and 4-wire measurements
2 extra channels for current measurements up to 2 A each

DM304 4 x 8 Matrix Switch

The DM304 4 x 8 Matrix (for the DAQ3120) is a dedicated switch module providing up to 32 cross-points in a 4 row by 8 column matrix. This module allows different test equipment to connect to multiple points on the device under test (DUT) at the same time. Additional DM304 modules can be wired together to expand the number of rows or columns, reaching up to 96 cross-points.

Product Features

32 2-wire cross-points
3 ms switching speed
300 V and 1 A maximum
Expandable to 96 cross-points

DM303 40-CH Single-ended Multiplexer

The DM303 40-CH Single-Ended Multiplexer (for the DAQ3120) is the highest density module with 40 single-wire inputs using armature relays for achieving scanning speeds up to 80 channels per second. All inputs connect to a common signal ground, making it suitable for applications in battery testing, component characterisation, and benchtop testing. The common signal ground line is isolated from ground and can be floated up to 300 V. This module also supports 2-wire internal measurements except current.

Product Features

Scanning speed up to 80 channels per second
Single-wire switching for common low applications
Supports 2-wire measurement (except current)
Channel-to-ground isolation

DM301 20-CH Multiplexer with 2 Current Channels

The DM301 20-CH Multiplexer (for the DAQ3120) with 2 current channels is the most versatile module with armature relays for achieving a maximum input of 300 V and a scanning speed of 80 channels per second. The two additional current channels measure up to 1 A each without the need for external shunts. Similar to the DM300, the 20 inputs are split into two banks with a switch to make 4-wire measurements. Both 2-wire and 4-wire channels can be mixed on the same module.

Product Features

Scanning speed up to 80 channels per second
2-wire and 4-wire measurements
Built-in cold junction reference for thermocouples
300 V maximum input
2 extra channels for direct current measurements up to 1 A each
