INFORMATION
AND ORDERING
Description
The 2002ALM family of trip-amplifiers can accept a wide
range of inputs including 4-20mA, thermocouple, RTD
and voltage types. 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 or 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 user-configured. For the current and
voltage input version the range may also be re-
configured. 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.
Other ranges and thermocouple types are available as detailed in the product
description, please contact our sales department.
