The OS-0426 module is designed to control up to 16 loads of 48 ÷ 230 V AC / 2 A. The outputs are realized by semiconductor switches. 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 switching circuits are protected by an RC element.
The power consumption of the module is max. 7 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 OS-7411 module output circuits is max. 0.6 W for one connected external module ( 16 outputs)). For the given example ½ OS-7411 + OS-0426, the power consumption from the 24 V DC source is 7.6 W.
Max. switching current depending on the ambient temperature of the module:
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. 11.3.9.1.
