SC2002ALM-HL
Dual Trip Amplifier
Wide Range of User Configurable Inputs
Isolated Input Stage
Setpoints Available as 0-10V, (0-100%) on terminals9&12
2 Setpoints with Configurable Trip Action & Fail-safe mode
D.C or A.C. Power Supply Options, See 4002-ALM for Mains Version
The SC2002ALM-HL trip amplifier can
accept a wide range of user configurable
inputs including 4-20mA, 0-20mA, 0-5V
and 0-10V. The unit can have up to two relay
outputs and each can operate as a high or a
low trip; alternatively latching operation
using both trip points can be configured.
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 are user-configurable using
internal DIP switches. This minimises the
number of spare units required.
The input stage is fully isolated and the
high level input current or voltage and
range may be configured. Separate
products are available for thermocouple
and RTD inputs.

Notes
Setpoints are adjusted by 20 turn potentiometers on the front panel.
Setpoints can be checked by measuring the 0-10V (0-100%) voltage on terminals 9 &12
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.
