Passive Current Transducers for Sinusoidal Alternate Currents From 0... A/0...5 A (-SW) Passive current transducer without power supply Measuring range A and 5 A AC, reconnectable Available with threshold value switches I U, I. Description (-SW) passive current transducers convert sinusoidal alternate currents from and 5 A into analog standard signals of 0 0 ma or 0 V. Modules acquire the necessary power for signal conversion from the measuring circuit so that a separate supply is not required for the transducer. The -SW current transducer has an additional limit monitor. The limit value and an alarm suppression time are set using two potentiometers on the front of the housing. One Form A and one Form B contact are available for the signaling on the output side. The appropriate switching state is displayed using LEDs. Both module versions are electrically isolated from one another on the input and output side. Safety Note: -SW passive current transducers are not suitable for safety circuits because there is no response at the relay output if the input current fails. Headquarters: Phoenix Contact GmbH & Co.

J.) < 750Ω =0...0mA If the 0-0 ma current and the 0- V voltage signal are required simultaneously, this can be implemented by connecting the terminal points according to the diagram opposite: Terminal points and 0, are used to close the current path. The voltage signal 0- V can be tapped (by leading back the current via the internal Ω resistor) on the output side of connections 0 and!. Since the total of all loads in the current path must not exceed 750 Ω, a maximum external load of 50 Ω is to be maintained for this connection method. In the voltage path, loads of kω must not be exceeded. Additional measuring errors, which must be taken into account, can be found in the Technical Data.

Jumper Position (Voltage Output/Limit Value Indicator) The 0- V signal is received by connecting terminal points 0 and!. In the voltage path, loads of kω must not be exceeded. Additional measuring errors, which must be taken into account, can be found in the Technical Data. J In jumper position, there is an option with the -SW module, to use the device without an analog output, i.e., purely as a limit value indicator. > kω =0...V. Settings (SETPOT/TIME) for -SW The desired current limit value is set for the MCR- SLP-/5-UI-0-SW module using the SETPOT potentiometer. The TIME potentiometer enables an additional alarm suppression time of 0. 6 seconds. This means that the relay is only activated if the current limit value is still being exceeded after the alarm suppression time has elapsed. This function is useful, for example, if on starting AC motors, no alarm is to be triggered due to the high startup current. 5.
