Digital Data Acquisition Manufacturer,Supplier and Exporter in India
Product Code : EL-TWL-10432
Jlab Export is a leading Digital Data Acquisition Manufacturer,and suppliers in India
Digital Data Acquisition gives a PC 32 isolated digital channels, 16 inputs and 16 outputs, for reading switches and driving relays. The inputs take 5–50 V DC signals or dry contacts, each output sinks up to 100 mA, and all channels are isolated to 2500 V DC. The unit runs on USB power, links over USB or Ethernet and has a timer/counter.

Automation Practicals for Students
A good first task joins the 24 V toggle switch outputs of a PLC Trainer to the isolated inputs. Students flip each switch and watch the matching bit change on the PC screen. They then use the timer/counter to count presses of the limit switch on a Basic PLC Trainer, which works as a dry contact.
On the output side, students wire a 24 V relay coil and an indicator lamp to two channels, powered from a Power Supply 0-30 Volts 3 Amp. A short program then turns them on in sequence, the start of a small conveyor or door control project.
Frequently Asked Questions
What is a dry contact input?
A dry contact is a plain switch or relay contact that carries no voltage of its own. With dry contact support, the input senses the contact opening and closing, so push buttons and limit switches can be wired straight to the terminals.
Why are the channels isolated?
Isolation keeps the field wiring and the PC on separate grounds. The 2500 V DC figure is what the barrier between them is rated to hold off. It protects the computer from spikes and wiring faults on the machine side.
What can the outputs switch?
Each isolated output sinks up to 100 mA, enough for relay coils, indicator lamps and small solenoids drawing less than that. The load needs its own DC supply, and a relay coil should have a diode across it to absorb the switch-off spike.
Which input voltages can it read?
The isolated inputs accept 5 to 50 V DC. That covers 5 V logic, 12 V signals and the 24 V signals used on most PLC and sensor panels.
Does the unit need a separate power supply?
No. It is powered from the USB port. Devices on the outputs, such as relays and lamps, still need their own supply wired through the output channels.
