  1. Single Channel Isolating Signal Converter with Sample & Hold Function - DC Powered - DIN Rail Mounting

    Single Channel Isolating Signal Converter with Sample & Hold Function - DC Powered - DIN Rail Mounting
    An Isolating Signal Converter with a built-in Sample and Hold Function. Includes a trigger function that will either allow the output to continuously follow the input or hold the last input reading when the trigger function is applied. The analogue input and the output stages of the instrument are powered from separate secondaries of the inverter maintaining 3 port isolation.
  2. Single Level Trip Amplifier - DC Powered - DIN Rail Mounting

    Single Level Trip Amplifier - DC Powered - DIN Rail Mounting
    Single Level Trip Amplifier from a single process signal input. The trip action can be arranged so that the Alarm condition can be above (High Trip) or below (Low Trip) the set point, and that the relay can be either normally energised to de-energise in the Alarm condition (Fail-Safe), or normally de-energised to energise in the Alarm condition (Non Fail-Safe).
  3. Single Level Trip Amplifier - Mains Powered - Bulkhead Mounting

    Single Level Trip Amplifier - Mains Powered - Bulkhead Mounting
    Single Level Trip Amplifier from a single process signal input. The trip action can be arranged so that the Alarm condition can be above (High Trip) or below (Low Trip) the set point, and that the relay can be either normally energised to de-energise in the Alarm condition (Fail-Safe), or normally de-energised to energise in the Alarm condition (Non Fail-Safe).
  4. Single Level Trip Amplifier - Mains Powered - DIN Rail Mounting

    Single Level Trip Amplifier - Mains Powered - DIN Rail Mounting
    Single Level Trip Amplifier from a single process signal input. The trip action can be arranged so that the Alarm condition can be above (High Trip) or below (Low Trip) the set point, and that the relay can be either normally energised to de-energise in the Alarm condition (Fail-Safe), or normally de-energised to energise in the Alarm condition (Non Fail-Safe).
  5. Single Level Trip Amplifier - Mains Powered - Eurocard Open Sub Rack Mounting

    Single Level Trip Amplifier - Mains Powered - Eurocard Open Sub Rack Mounting
    The T100 is a Single Level Trip Amplifier from a single process signal input. The trip action can be arranged so that the Alarm condition can be above (High Trip) or below (Low Trip) the set point, and that the relay can be either normally energised to de-energise in the Alarm condition (Fail-Safe), or normally de-energised to energise in the Alarm condition (Non Fail-Safe).
  6. Single Level Trip Amplifier - NAMUR NE43 - DC Powered - DIN Rail Mounting

    Single Level Trip Amplifier - NAMUR NE43 - DC Powered - DIN Rail Mounting
    The BM9431 is a DIN rail mounting (TS35) Single Level Trip Amplifier monitoring a 4 to 20mA input signal. It has one process trip and additional internal alarm relays/LEDs for "Out of Range Input" and "Power OK/Fail".
  7. Single Level Trip Amplifier - NAMUR NE43 - Mains Powered - DIN Rail Mounting

    Single Level Trip Amplifier - NAMUR NE43 - Mains Powered - DIN Rail Mounting
    The BD9431 is an AC powered DIN rail mounting (TS35) Single Level Trip Amplifier monitoring a 4 to 20mA input signal, which can be loop powered from the BD9431. It has one process trip and additional internal alarm relays/LEDs for "Out of Range Input" and "Power OK/Fail".
  8. Single Level Trip Amplifiers

    Single Level Trip Amplifiers
    Single level trip amplifiers operate from a single process input, with a single trip action which can be arranged so that the alarm condition is triggered either above or below the defined set point. 
  9. Single Output Stabilised Instrument Power Supply - Mains Powered - DIN Rail Mounting

    Single Output Stabilised Instrument Power Supply - Mains Powered - DIN Rail Mounting
    Stabilised variable transducer power supplies with one isolated output. The output can be user adjusted by means of a potentiometer located in the fascia of the instrument. The range of variation is between 5 Volt DC and 24 Volt DC.
