Frequently Asked Questions - 10A61-2 Daytronic

How do I install the Daytronic 10A61-2?

Mount the module on a DIN rail or flat surface using the provided brackets. Connect the power supply (100-240 VAC) and input/output signals via screw terminals. Ensure proper grounding.

What is the input voltage range of the 10A61-2?

The input voltage range is selectable via DIP switches: ±10 V, ±5 V, or ±1 V. Refer to the manual for switch positions.

How do I calibrate the module?

Calibration requires a precision voltage source and a multimeter. Adjust the offset and gain trim pots on the front panel while monitoring the output. Periodic calibration is recommended.

What do the LED indicators mean?

The green LED indicates power, the red LED indicates an overload condition. If the red LED lights, check the input signals and connections for short circuits or overvoltage.

Can I use the 10A61-2 with 4-20 mA sensors?

Yes, by connecting a precision resistor (e.g., 250 Ω) across the input terminals, you can convert 4-20 mA to 1-5 V. Set the input range to ±5 V and adjust gain as needed.

How do I clean the device?

Disconnect power and use a soft, dry cloth to wipe the exterior. Do not use solvents or abrasive cleaners. Keep the ventilation slots free of dust.

What is the maximum cable length for input signals?

For best accuracy, keep input cables under 10 meters (33 feet). Use shielded twisted-pair cables and ground the shield at one end to reduce noise.

Does the 10A61-2 have output isolation?

The input and output are not isolated from each other. The module shares a common ground. For isolated applications, use an external isolator.

Where can I find the user manual?

The user manual is available for free download on the Daytronic support website or at notice-facile.com. Search for model 10A61-2.

What spare parts are available?

Spare parts include replacement screw terminal connectors, DIP switch covers, and mounting brackets. Contact Daytronic or an authorized distributor for ordering.

USER MANUAL 10A61-2 Daytronic

The Model 10A60-4 is a general-purpose conditioner allowing input of up to four external voltage signals. Mixed as desired, these may originate from DC-to-DC LVDT's, potentiometer-type sensors, and other 2-wire analog signal sources that provide their own power supply. Or they may represent the outputs of other instrument systems having various voltage levels and grounding configurations.

Inputs can be either floating (differential) or grounded (single-ended). With 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. Chopper-stabilized DC amplification with active low-pass filtering yields smooth and stable measurement of the true average value of the input variable, even in the face of substantial dynamic content.

2 TRANSDUCER CONNECTIONS

The Model 10A60-4'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.

Cabling for floating inputs is given in Fig. 1(a). NOTE: To minimize signal noise, it is recommended that for a floating (ungrounded) input with high common-mode impedance, the COMMON pin be tied to the -SIGNAL line at the connector. Cabling for grounded inputs is shown in Fig. 1(b).

3 SETUP AND/OR OPERATING CONSIDERATIONS

3.a CONFIGURATION AND CALIBRATION

For initial configuration of ANALOG INPUT CHANNELS dedicated to a specific Model 10A60-4 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 10A60-4 channel "type" codes, see Table 1, above.

In System 10, you can use two calibration methods with the Model 10A60-4:

ABSOLUTE CALIBRATION

Described in Manual Section 1.G.3.b, this method is applicable only when the 10A60-4 is being used to measure voltage itself. In this case, the user need only specify an appropriate SCALING FACTOR ("m" coefficient), once the 10A60-4-based input channel has been properly configured.

Thus, to calibrate a 10A60-4-based Channel No. "x," you need only turn ON the system EEPROM SWITCH and then apply the following SCALING FACTOR (EMM) command:

$$ E M M x = (1. 2 5) m [ C R ] $$

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.

Note that for the Model 10A60-4 (ONLY), the entered "m" value must be 1.25 times the stated full-scale range for the respective channel "type."

If, for example, a voltage-measuring 10A60-4 channel is "typed" as "5D" (corresponding to a full scale of ±5 V-DC) and you want the channel to read hundredths of a volt, you would enter an "m" value of "6.25" (= 1.25 x 5.00).

NOTE: The accuracy of "absolute" calibration of a 10A60-4-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 10A60-4 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 10A60-4 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.
