Description
The 4 0 0 2 ALM trip-amplifier can accept a wide range of inputs
including 4 -2 0 mA, ther mocouple, 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 can also produce an isolated high level output.
4 0 0 2 ALM - HL for DC Cur rent and Voltage
0-20mA, 4-20mA, 0-10mA into 15Ω/ 30Ω
0-1V, 0-10V, 1-5V, into 100kΩ/ 1MΩ
Min and Max full scale ranges:
DC current
DC voltage
0 to 50µA
0 to 100mV
0 to 10A
0 to 300V
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.
Note: For input voltages greater than 30Vac or 60Vdc a divider unit must
be specified.
4 0 0 2 ALM - TC for Ther mocouples
Types E, J, K, N, R, S and T non-linearised
Ranges 0-250, 0-500, 0-1200˚C (Others available)
Auto cold junction compensation. Open cct t/ c can drive either
upscale or downscale
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:
4 0 0 2 ALM - RTD for Resistance Ther mometers
2 or 3 wire Pt100 or other, linearised output
Ranges 0-250, 0-500, -100-100˚C (others available)
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.

Notes
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.
