Dual Trip Amplifiers 2002ALM
The 2002ALM family of trip-amplifiers can accept a wide
range of inputs including 4-20mA, thermocouple, RTD
and voltage types
• Wide range of configurable inputs
• Configurable trip action and failsafe mode
• Isolated input stage
• Setpoints available on front panel
The unit can have up to two relay outputs and each can operate as a high or a low trip.
The relay outputs are single pole change-over relays with mains voltage rating. Each trip can be configured so that the alarm condition can be above or below setpoint. The relays can be energised or de-energised in the alarm condition, satisfying fail-safe and non-fail-safe applications. In addition the alarm LEDs can be selected to light when the relay is either on or off. All these options may be specified at point of order but are user configurable using internal link selectors. This minimises the number of spare units required.
The input stage is fully isolated as an option and the input type can be userconfigured. For the current and voltage input version the range may also be reconfigured. For the thermocouple the RTD input versions the device type and range are selectable. Again these can also be specified at point of order.
It is also possible to specify a latching function on the relay outputs, making the unit ideal for lock-out applications. The unit can be powered from a wide range of power supplies, ranging from 12Vdc to 24Vac, please specify with order.
