Isolation and measuring transducer STR/BTR - HSB
For the conversion of a standard electrical signal into another standard signal or/and electric isolation, the STR/BTR isolation transducer from HSB Electronics uses the terminals A1 and A2 for connection to 24VAC/DC or 230VAC. The green LED indicates the connection to the power supply, which must be continuously connected to the transducer.
The STR/BTR transducer acquires a standard signal 0(4)...20mA/ 0(2)...10V and converts it into an independent current or voltage signal. The measuring circuit is electrically isolated from the power supply. The desired configuration is selected with the DIP switches on the relay´s front panel. The STR/BTR isolation transformer has three-way isolation.

Measuring Over Current Relay SIR - HSB
The measuring over current relay from HSB monitors an AC or DC current connected to the terminals B1/B2. If the current is higher than the value selected with potentiometer I>, the relay switches to its working position (yellow LED is on). The relay switches back to its rest position as soon as the monitored current is below the adjusted value plus the adjusted hysteresis.
The SIR current measuring relay from HSB has two separate inputs for DC and AC supply. For a 230VAC power supply use the terminals A1/A2. For a 24V AC/DC power supply use the terminals A3/A2. The green LED indicates the connection of the power supply. Continuous presence of the power supply (A1/A2 or A3/A2) is required for measuring. The measuring circuit is galvanically isolated from the supply. The response time can be adjusted between 0 ... 10 seconds. The relay continuously monitors the rectified value of the input signal.

Multi-function timers SMR - HSB
The multi-function timers SMR from HSB offers multiple time functions. Functionality can be selected by DIP switch. Advantage of this device is low cost stock-keeping because of its use in universal applications.
The SMR multifunction timer offers 7 selectable timing functions and 8 different timing intervals in one unit. The function and timing intervals can be adjusted with DIP switches on the front panel of the relay. The multifunction timer can operate on either AC or DC voltage using two separate connections. For a 230V AC power supply use the terminals A1/A2. For a 24V UC power supply use the terminals A3/A2. The green LED indicates the connection to the power supply. Timing commences with the connection of the power supply or contact controlled on terminals B1/B2 or voltage controlled on terminal B1.

Optocouplers – Murrelektronik
Minimum space – maximum functionality.
MIRO – the coupling module in terminal block format.
Coupling modules in the form of relay and opto-coupler modules are indispensable in controller and system construction. Coupling modules are needed for signal amplification, signal adaptation, potential separation, potential-free transfers to other parts of the system and for increasing interference immunity.
Using the MIRO range of modules will cut your costs and block out interference and overvoltage from PLC boards and construction cards. MIRO interface modules will increase the operational reliability of your system and reduce the size of your switch cabinet.
