Trip Amplifiers

The family of Trip Amplifiers available range from a single setpoint loop powered device to a powered dual setpoint unit with isolated re-transmission and an LED display of inputs and setpoints.

The 4002ALM-6 24Vdc Dual Trip Amplifier

• Wide range of user configurable inputs
• Configurable trip action and fail-safe modes
• Isolated Re-transmission
• Isolated input stage and isolated transmitter supply
• LED display of input, setpoints and configuration

The 4002ALM-6  trip amplifier can accept a wide range of inputs including 4-20mA, thermocouple, RTD and voltage.

The unit performs the same basic functionality as the 2002ALM family above. but can also have options such as time delays on trips set using the front panel. In addition the 4002ALM-6 can re-transmit the input signal as a 4-20mA or 0-10V signal, and can display the input and the two setpoint values on the front panel LED display.

Various trip latching options are available, for example one relay can be latched when a high level is reached and un-latched when the signal reaches the lower setpoint. All of this functionality is in a small DIN rail mount enclosure only 22.5mm wide!
