Шаблон:DisplayTitle: Discrete inputs dry contact module (WBIO-DI-DR-8)
Applicability
Connection of pulse counters, buttons, switches, sensors with dry contact output.
Technical specifications
Contains 8 dry contacts inputs with group galvanic isolation. The scheme of inputs is shown in the figure. The terminal is supplied by ~ 4.5 V voltage, when the ground fault,flows a small (1mA) current, causing the operation of the input.
| Parameter | Value |
|---|---|
| Number of inputs | 8 |
| Isolated input groups | 1 |
| Input type | dry contact,
the opening by the current at ground fault |
| Operation condition | GND input lockout |
| Tripping current | 1 mA |
| Minimum pulse width to trigger | 10 MS |
| Minimum time between consecutive signals | 5 MS |
| Voltage of "wetting" | 4.5 V |
| Module type | "I" (inverted address scheme) |
| Maximum power consumption | 0.1 W |
| Width, DIN units | 2 |
| Size | 36,3x90,2x57,5 mm |
| "'Terminals and wire section'" | |
|---|---|
| Recommended wire cross-section with TSVI, mm2 | 0,75 — 1 |
| Length of the standard sleeve NSVE, mm | 8 (10 for adjusting screwless terminal blocks) |
| Torque of screws, N∙m | 0,2 (for screw terminals) |
Connection to the controller
See Activating the modules in the web interface of the controller
Connection
Sensors/counters with pulse outputs/buttons.
Such devices form a signal by closing two wires that are suitable for them. Connect one wire to the GND terminal of the module. Connect the second wire to the Dx terminal. Some counters have a pulse output on the optocoupler, then the two wires have a polarity - "plus" and "minus". In this case, minus is connected to GND, plus - to Dx.
Devices with open collector output.
Both device and controller must be connected to the common grounding bus. Connect the "open collector" output to the Dx terminal.
The module inputs are galvanically isolated from the controller. Therefore, the ground GND of the module and the controller may be different.
