Ferndown Industrial Estate Wimborne, Dorset 21 7BH PE SC2002ALM-HL 2018 Telephone +44 (0) 1202 897969 Email:sales@cynergy3.com Made in the UK SC2002ALM-HL Dual Trip Amplifier Wide Range of User Configurable Inputs Isolated Input Stage Setpoints Available as 0-10V, (0-100%) on terminal s9&1 2
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.

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.
