Description
The 4002ALM trip-amplifier can accept a wide range of inputs
including 4-20mA, thermocouple, R TD and voltage types. The unit
can have up to two relay outputs and each can operate as a high or
low trip. The unit can also produce 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 LEDs can be selected to light when the relay is either
on or off.
The input stage is isolated as standard with the inputs user-reconfigurable
to cover 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.
The following applications are also possible:
One output relay is energised when the input reaches the high setpoint
and is latched on until the lower setpoint is reached. The reverse operation
is also possible. This is ideal for applications such as pumping out. All the
above options are user-configurable but can be specified at point of order.
Default configuration is set to Hi/Hi alarms with LED on when relay
energised. Please specify at time of ordering if other combinations are
required.

Setpoints are adjusted by 20 turn potentiometers on the front panel.
Setpoints can be checked by measuring 0-10V (0-100% voltage on the front panel terminals.
H/H, H/L, L/H, LL, fail-safe, non-fail-safe and LED options are user selectable using internal links.
Hysteresis is set at 1.0%but other values are possible, please specify if required.
The process input level is available as 0-1V (0-100% on front panel or on 3 digit LED display.
