DAG-Z2 Counter/Preset Counter Overview
The KOBOLD DAG-Z2 is a compact panel-mount counter/preset counter in a 74 x 32 mm format that can be set as either a single or a double counter, each with independent settings. It accepts input frequencies from 1 Hz to 100 kHz, runs on a universal 24 to 230 VAC/VDC supply, and provides two relay outputs.
Three universal digital inputs (NPN, PNP, TTL) can be used for bidirectional encoder readings, an UP/DOWN counter function, or LOCK/HOLD to lock the current visualization. One analog input allows setpoint modification by an external potentiometer. With a brilliant display, a rugged housing, and a variety of modes and scaling options.
Inputs and Counting Modes
The DAG-Z2 has three digital inputs (I1, I2, I3) that can be configured as NPN, PNP, or TTL, with programmable thresholds for activation as HIGH/LOW, active rising edge, or level triggered. Input frequency is rated from 1 Hz to 100 kHz, and input functions include counting direction, stop, hold, wait, and setpoint input on I3.
Count modes include:
- Bidirectional encoder, with phase A on I1 and phase B on I2
- UP mode or DOWN mode on a single input
- UP on I1 with reverse direction on I2
- UP on I1 and DOWN on I2
- UP on I1 with count lock (enable/lock) or display hold (enable/hold) on I2
Scaling pairs input counts (1 to 9999) with visualized counts (1 to 9999), with 0 to 3 decimal places.
Relay Outputs and Setpoints
Two relay outputs are provided: 1 SPDT relay and 1 N/O contact, each rated at a maximum of 5 A at 230 VAC. Two red indicators show relay output status and light when an output is active. Setpoints appear on the lower display line and are entered with the front keys or with an external potentiometer on input I3.
Each output can be assigned to counter 1 or counter 2. Output modes include activation when the counter equals the setpoint, activation for a set duration in time or counts, and a latched output cleared by counter loading.
Setpoint Adjustment by External Potentiometer
Input I3 can be used for connecting a potentiometer (0 to 5/10 kΩ) for setting the nominal value, with a resolution of 1000 steps. The manual specifies that the cursor connects to pin I3, since a wrong connection may damage the potentiometer and lock the device, and that upper and lower limits stay within 1000 units.
Display, Programming, and Data Security
The 2-line LED display shows the count value on the upper line in 4-digit, 0.40 in (10.2 mm) green digits and the setpoint on the lower line in 4-digit, 0.30 in (7.6 mm) red digits. Programming is menu-guided via four front keys, and access to setpoints, alarm values, and parameters is password protected.
A yellow indicator shows serial communication, and the datasheet lists programming by front keys or software.
Optional Memory Card
An optional memory card (order no. SFUR0KIT) copies parameters and setpoint values from one DAG-Z2 to another. Data can be loaded with the device powered, or with the device disconnected from power using the card's internal battery, which has a life of about 1000 uses.
Power Supply, Excitation, and Wiring
The DAG-Z2 runs on a universal supply of 24 VAC/VDC to 230 VAC/VDC ±15%, rated 2 W on the unit label. A 24 VDC excitation output for sensors is rated at a maximum of 30 mA with a 24 VAC supply, 40 mA with a 24 VDC supply, and 60 mA with a 110 to 230 VAC supply.
Connections are made at 12 screw terminals:
- Terminals 1 and 2: power supply
- Terminals 3 to 5: relay output Q1 (SPDT)
- Terminals 6 and 7: relay output Q2
- Terminal 8: ground
- Terminal 9: 24 V output
- Terminals 10 to 12: inputs I3, I2, and I1
Dimensions, Mounting, and Environmental Ratings
The DAG-Z2 measures 3.03 in W x 1.38 in H x 2.09 in D (77 x 35 x 53 mm) and mounts in a 1.12 x 2.78 in (28.5 x 70.5 mm) panel cut-out. Protection is IP65 from the front (with rubber seal) and IP20 from the back. The black plastic housing weighs approximately 3.5 oz (100 g).
The installation drawing suggests a panel thickness of 0.08 to 0.31 in (2 to 8 mm). Rated ambient conditions are 32 to 113 °F (0 to 45 °C) and 35 to 95% RH, non-condensing.
Common Questions about DAG-Z2 - Counter/Preset Counter
There are two operating modes: single counter or double counter, all with independent settings. Pulses arriving on the digital inputs are counted up or down, and each relay output switches according to its configured mode, for example when the counter value equals setpoint 1 or for a set duration after that point.
All three inputs accept NPN, PNP, or TTL signals. Wiring examples in the manual cover PNP proximity sensors in 3-wire or 2-wire versions, NPN or PNP contacts, and an encoder wired phase A to I1, phase B to I2, and phase Z to I3. A 24 VDC excitation output on terminal 9 can supply the sensors.
It has an input frequency from 1 Hz up to 100 kHz. There is also a separate digital filter delay for each of the three inputs, selectable in 0.5 ms increments from no delay to a maximum of 100.0 ms.
Output Q1 is an SPDT relay and output Q2 is a normally open (N/O) contact. According to the datasheet, both are rated for up to 5 A at 230 VAC. Q1 uses terminals 3 to 5 and Q2 uses terminals 6 and 7, and a red front indicator lights for each active output.
It accepts 24 VAC/VDC through 230 VAC/VDC with a tolerance of ±15%, wired to terminals 1 and 2. The wiring label lists power consumption as 2 W, and the 24 VDC excitation output is rated up to 60 mA when the unit runs on 110 to 230 VAC.
It needs a 28.5 x 70.5 mm (1.12 x 2.78 in) opening. The front bezel is 77 x 35 mm (3.03 x 1.38 in), depth behind it is 53 mm (2.09 in), and a panel 2 to 8 mm (0.08 to 0.31 in) thick is suggested for mounting. The rubber seal gives the front face an IP65 rating.
Yes. A potentiometer of 0 to 5/10 kΩ wired to input I3 can modify Set1 or Set2, with an accuracy of up to 1000 points.
Use the optional SFUR0KIT memory card. It transfers parameters and setpoint values between units either while the receiving unit is powered, confirmed from the front keys, or while it is unpowered, using the card's own battery (rated for about 1000 uses). It is recommended to update the card first.
It can. The P-02 power-off memory parameter chooses whether nothing is saved, only counter 1, only counter 2, or all counters when power is removed. Disable is the factory default, so counts are stored at power-off only after this parameter is changed.
Hold the FNC key for 3 seconds until the display shows 0000 on the first line and PASS on the second. Use the arrow keys to enter the password digit by digit, press SET to confirm, and the device loads its default settings. Then switch the device off and restart it.
