Frequently Asked Questions - 10A63-2 Daytronic

What is the Daytronic 10A63-2?

The Daytronic 10A63-2 is a signal conditioning module designed for strain gage, load cell, and voltage inputs, providing amplified and filtered analog output.

How do I power the 10A63-2?

Connect the device to a standard power outlet using the supplied AC power cord. The module accepts 115/230 VAC at 50/60 Hz. Ensure the voltage selector switch is set correctly.

What is the input range for the 10A63-2?

The input range is adjustable via internal jumpers. Typical ranges are ±10 mV, ±30 mV, ±100 mV, and ±1 V for strain gage or voltage inputs.

How do I connect a strain gage to the 10A63-2?

Use the screw terminals labeled EXC+, EXC-, SIG+, SIG-, and SHIELD. Connect the strain gage in a Wheatstone bridge configuration. Refer to the manual for wiring diagrams.

Can I use the 10A63-2 with a 4-20 mA output?

No, the 10A63-2 provides a ±10 V analog output only. For current outputs, an external converter is required.

How do I calibrate the 10A63-2?

Use the zero and span potentiometers on the front panel. Apply a known zero input and adjust ZERO until output is 0 V, then apply a full-scale input and adjust SPAN for 10 V output.

What is the bandwidth of the 10A63-2?

The bandwidth is 1 kHz typical. A low-pass filter can be enabled via an internal jumper to reduce noise.

Is the 10A63-2 compatible with PC-based data acquisition?

Yes, the ±10 V output can be connected to any analog input board or DAQ device. Ensure the input range of the DAQ matches the output.

How do I clean the 10A63-2?

Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or solvents. Keep the ventilation slots free of dust.

Where can I get replacement parts or service?

Contact Daytronic customer support or an authorized service center. Always use genuine Daytronic parts for repairs.

USER MANUAL 10A63-2 Daytronic

The Model 10A63-2 is a high-accuracy conditioner allowing input of one or two external voltage signals. Mixed as desired, these may originate from DC-to-DC LVDT's, potentiometer-type sensors, and other 2-, 3-, or 4-wire analog signal sources, either grounded or floating—or they may represent the outputs of other instrument systems having various voltage levels and grounding configurations.

The 10A63-2 offers a wide range of input voltages. Its differential inputs, generous common-mode range, and excellent common-mode rejection eliminate ground-coupling errors and other problems normally associated with off-ground signal sources. Nominal 5 V-DC excitation is provided for external sources that require it. "1/2 Bridge Completion" terminals allow "zero-center" operation of potentiometers with resistance from 1 to 10k .

2 TRANSDUCER CONNECTIONS

The Model 10A63-2's I/O CONNECTOR mates with Daytronic CONDITIONER CONNECTOR No. 60322, shown in Fig. 1.5 (in Manual Section 1.E.1). Table 2 gives standard pin assignments for the I/O Connector.

2-wire cabling for analog sources with no excitation from the 10A63-2 is given in Fig. 1(a); 3-wire zero-to-full-scale potentiometer cabling is given in Fig. 1(b); 3-wire zero-center potentiometer cabling is given in Fig. 1(c); and 4-wire DC-to-DC LVDT cabling is given in Fig. 1(d).

Note that floating (ungrounded) inputs are to be grounded at the site of the signal source, and not at the CONDITIONER CONNECTOR. Note also that the Model 10A63-2 has "1/2 BRIDGE COMPLETION" terminals to allow bipolar ("Zero Center") operation of potentiometers. As shown in Fig. 1(c), the 1/2 BRIDGE is powered by the potentiometer excitation. Although this excitation is normally supplied by the 10A63-2—as shown in the figure—the user may replace it with his own precision source, if desired. In this case, Pins 1 and A (for Channel 1) or Pins 6 and F (for Channel 2) would not be used. The 1/2 BRIDGE terminals would tie into the user's excitation lines (Pin 2 or 7 to +EXCITATION; Pin B or H to -EXCITATION).

3 SETUP AND/OR OPERATING CONSIDERATIONS

3.a CONFIGURATION AND CALIBRATION

For initial configuration of ANALOG INPUT CHANNELS dedicated to a specific Model 10A63-2 card when used in System 10, see the general remarks on System 10 "real-channel" configuration in Manual Section 1.G.1 and elsewhere in the System 10 Guidebook. For 10A63-2 channel "type" codes, see Table 1, above.

In System 10, you can use two calibration methods with the Model 10A63-2:

ABSOLUTE CALIBRATION

Described in Manual Section 1.G.3.b, this method is applicable only when the 10A63-2 is being used to measure voltage itself. In this case, the user need only specify an appropriate SCALING FACTOR ("m" coefficient), once the 10A63-2-based input channel has been properly configured.

Thus, to calibrate a 10A63-2-based Channel No. "x," you need only turn ON the system EEPROM SWITCH and then apply the following SCALING FACTOR (EMM) command:

EMM x = m [CR]

where “m” equals the full-scale range corresponding to the channel’s present TYPE designation, expressed to the precision desired for the channel’s data readings. Channel “type” codes and associated full-scale ranges are given in Table 1, above. If, for example, a voltage-measuring 10A63-2 channel is “typed” as “6A” (corresponding to a full scale of ±50 V-DC) and you want the channel to read tenths of a volt, you would enter an “m” value of “50.0.”

NOTE: The accuracy of “absolute” calibration of a 10A63-2-based channel is limited to ±1.5% of full scale.

Two-Point (Deadweight) Calibration

Using the standard ZERO (ZRO) and FORCE (FRC) commands, this conventional "zero and span" method can be applied to a 10A63-2 channel if the received voltage input is an analog of another parameter which has one or more independently and accurately known calibration values. It can also be used to improve the ABSOLUTE calibration of an input that measures voltage itself (beyond the 10A63-2 card's inherent limit of ± 1.5% of full scale). The mainframe's EEPROM Write Protect Switch must be ON for the ZRO and FRC commands to be effective. See Manual Section 1.G.5 for a general discussion of this calibration technique.
