Features
Output type:Relay output,normally open(NO)contact,Form C(single-pole double-throw SPDT).
Status Indicator:Each output channel features a status indicator LED that visually displays the channel’s operating status.
Protection Function:It monitors the relay power supply voltage.If the voltage drops,an error signal is generated,illuminating the warning LED.This error signal can be read via the module bus.This monitoring function can be enabled or disabled via a parameter.
Communication Interface:It supports the Profibus-DP communication protocol,facilitating integration with other devices in automation networks.
Output Preset State(OSP):When an error is detected,OSP sets the output to a predetermined state.
Application Scenarios:Widely used in industries such as manufacturing,energy,and utilities,it can be used to control devices such as relays,solenoid valves,and motors.It can also be used for discrete control,alarms,and indications.
