IO modules/en

IO modules are joined to the connector on the side WB5.

IO module

Pinout slot for input-output modules

You can connect up to 8 modules: Up to 4 input modules (type I), and up to 4 output module (Type O and IO). WB5 automatically detects connected module and its type. Addresses are distributed sequentially. Connect up to 4 modules can be in any order. When a larger number should be connected first one type, then the other.

Communication Interface - I2C.

Digital Input Module type "dry contact" (WBIO-DI-DR-8)

WBIO-DI-DR-8 module

Contains 8 inputs for connecting "dry contacts" with the group galvanic isolation. The circuit inputs shown in Fig. On input is applied ~ 4.5V, ground fault current flows small (1mA), triggering input.

To input trigger pulse width must be at least 10 ms ???. The time between pulses - 5ms

Digital inputs DI

Digital Output Module (WBIO-DO-HS-8)

WBIO-DO-HS-8 module

Contains 8 outputs such as "High Side Switch" - when you turn on channel Vin voltage is supplied to the output.

Designed to control relays, low-voltage motors, etc.

Current up to 0,6A per channel. Built-in overvoltage protection (including load dump), overheat and short circuit protection.

Requires external power supply to the terminals 'Vin' and 'GND' .

Ground module must be connected with the ground controller!

Power supply from 11 to 45V.

The circuit of High Side Outputs module.

Relay Output Module (WBIO-DO-R3A-8)

WBIO-DO-HS-8 module

Contains 8 relays. Two of them are SPDT (NO / COM / NC).

Current is up to 8A per NO-NC (on / off) channel, and up to 3A for SPDT relay channels. Protection from arcing contacts.

Rated current is specified for resistive loads and 230V AC.

IO module with TTL-level (WBIO-DIO-TTL-8)

WBIO-DIO-TTL-8 module

It contains 8 GPIO channels with 5V level, the channels are configured by default as a "outputs." Up to 20 mA. Overvoltage protection up to 60V.
