The SC4002ALM-6 trip-amplifier 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
low trip. The unit also produces an isolated
high level output.
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 the
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 LED's can be selected to
light when the relay is either on or off.
The input stage is isolated from the output
and power supply and the inputs can be
user-reconfigured for several different
ranges if specified at point of order. In
addition there is an optional isolated
transmitter supply of 24Vdc, suitable for
exciting most standard transmitters.
In addition numerous functions can be
selected using the built-in menus including
latching functions, delay on or delay off and
an alarm delay on power up.
If you require any other special function
please contact us on the number below.
