The OR-0427 module is equipped with 8 relay outputs with changeover contacts. The module is equipped with a fixed terminal block with spring contacts. It is an external output module intended for connection to the output binary modules of the control system (eg connection to the OS-7410, OS-7411 and IS-7510 modules of the TC700 system). Each output is indicated by a light-emitting diode. The output contacts are protected by an RC element and a varistor.
The power consumption of the module is max. 6.6 W and it is necessary (to calculate the consumption from the 24 V DC source) to add the power consumption of the output circuits of the connected control module (eg the power consumption of the output circuits of the OS-7411 module is max. 0.6 W for one connected external module (16 outputs)). For the given example ½ OS-7411 + OR-0427, the power consumption from the 24 V DC source is 7.2 W.
The module is equipped with fixed terminal blocks with spring contacts and a removable R connector for connecting the control system (in case of using a shielded connection cable to the control system, the shield terminal is connected to the SHIELD faston connector) and a removable S connector for connecting the second eight outputs (external module with 8 outputs ). The connection of the connector is shown in Fig. 11.3.10.1.
