Frequently Asked Questions - 5M14V Daytronic

How do I connect a strain gauge to the 5M14V?

Connect your strain gauge to the input D-sub connector following the pinout diagram provided in the manual. Use a 4-wire configuration for best accuracy.

What is the maximum input voltage?

The maximum input voltage is ±10 mV for full-scale output. Do not exceed ±15 mV to avoid damage.

How do I set the zero offset?

Use the front panel zero potentiometer while monitoring the output voltage. Adjust until the output reads zero with no load on the sensor.

Can I use this with a 120 ohm strain gauge?

Yes, the 5M14V supports standard 120 ohm, 350 ohm, and 1000 ohm gauges. Select the appropriate excitation via internal jumper.

What is the output impedance?

The output impedance is 100 ohms. It can drive loads down to 10 kΩ without significant error.

How do I calibrate the gain?

Apply a known calibration signal (e.g., 2 mV/V) and adjust the span potentiometer until the output matches the expected value.

What filters are available?

The unit has a selectable low-pass filter with cutoff frequencies of 10 Hz, 100 Hz, or 1 kHz via internal DIP switches.

Is the unit isolated?

The 5M14V provides input-to-output isolation of 1500 V, protecting your measurement system from ground loops.

Can I power it from DC?

Yes, a 12V DC input is available via the rear terminal block. Ensure polarity is correct.

How do I reset the calibration?

To restore factory calibration, press and hold the reset button on the rear panel for 5 seconds. All adjustments return to default.

USER MANUAL 5M14V Daytronic

The Model 5M14(V) is a precision conditioner designed for TC-based temperature measurements requiring high input isolation. With built-in reference-junction compensation, it accepts up to four independent temperature signals from Types E, J, K, N, R, S, and T Thermocouples. All four thermocouple inputs must be of the same type. Sensors may be grounded or ungrounded, in any desired mix. An amplifier-per-channel design with chopper stabilization and active low-pass filtering allows highly responsive, amplified analog signals with or without linearization correction.

For the Model 5M14, the analog output signal is 5 Vdc and the 5M14V is 10 Vdc. These are nominal full scale voltages since the Module is based on a millivolt per degree C value. All setup of the module is accomplished via the front panel configuration switch settings - polarity over-range, TC type, filter setting, extended gain, and linearized or non-linearized output.

Model 5M14 Thermocouple Module

Access switch settings via the front panel of the 5M14 by gently pulling the clear plastic cover (from the bottom side) so the cover rotates open from the top. Use a small tool or finger to place the switches to the left or right position as you face the front of the module. This process can be done with or without power to the unit. Once completed, return the cover to the original position.

Open Thermocouple Detection (OTC)

Can be set per individual TC input to saturate the analog output signal full-scale positive or negative.

Note: when this condition exists the analog output can be as much as 12 Vdc. When an OTC condition occurs, the yellow LED indicator on the front of the module will illuminate.

TRANSDUCER CONNECTIONS

The Model 5M14(V) I/O CONNECTIONS are via non-removable screw terminals which will accept wire sizes from AWG 12 to 26. NOTE: unused thermocouple inputs should have their individual channels + and - terminals shorted together to prevent over-range LED light indication. Thermocouple wire should be directly attached to its corresponding screw terminals - never solder or use copper wire extensions which will cause cold junction compensation errors. Table 2 denotes screw terminal assignments.

3 CALIBRATION

The Model 5M14(V) does not require field calibration. Front panel selector switches, as shown below, will enable the correct linearization and cold junction temperature compensation to the thermocouple connected to the unit. All four thermocouples will be conditioned and linearized for the thermocouple type selected. Note: Depending on the switch selection, the conditioned output of the thermocouple signal(s) will be -1) Normal gain through-out the thermocouple's temperature specification to NIST tables. 2) Extended gain if the user desires amplification in a restricted temperature range. 3) Non-linearized which enables the Cold Junction Compensation and gain amplification only. In this mode it is expected that the external readout device connected to the 5M14(V) will perform the correct linearization operation for the application and connected thermocouple sensor(s).
