The IB-0402 module is intended for connection of up to 16 binary 24 V AC / DC signals with a common minus terminal from the controlled technology and their transfer to the control system module (eg connection to IB-7310, IB-7311, and IS-7510 system modules TC700). The module is equipped with a terminal block with spring contacts, each input is protected against overvoltage by a lightning arrester and transil and the status of the input is indicated by an LED diode.
The module is equipped with fixed terminal blocks with spring contacts and a removable R connector for connecting the control system (in the case of using a shielded connection cable to the control system, the shield terminal is connected to the SHIELD faston connector). The connection of the connector is shown in Fig. 126.96.36.199.
The module itself does not draw any current from the 24 VDC supply (terminal block M, N). The power consumption is determined by the input current of the connected input module of the control system (eg the power consumption of the input circuits of the connected IB-7311 module is max. 1.5 W for one connected IB-0402 module (16 inputs)). For the given example ½ IB-7311 + IB-0402, the power consumption from the 24 V DC source is 1.5 W.
