SC20ALMDC Loop Powered Trip Amplifier High or Low Alarm Option Low Voltage Drop Isolated Input Stage Setpoints Available on Front Panel as 0.4-2V Signal (4-20mA) LED Indication Of Alarm Unique Low Cost Solution General Specification Recommended Operating Conditions Input Current 4-20mA Relay Contact Voltage 110Vac Relay Current (max) 130mA 110Vac / 24Vdc Output Resistance 24 (on) 110Vac Type Environmental Conditions Storage Temperature -40 - 70 C The SC20ALMDC is a 4-20mA direct current Operating Ambient 0 - 55 C loop powered trip amplifier. The device Relative Humidity 0 - 90 % RH derives its power from the input signal and therefore requires no external power supply. Technical Specifications The output of the SC20ALMDC is a single Parameter Min Typ Max Comments pole, normally open, solid state relay which Supply Voltage Loop power can be configured to close either above or Supply Current (mA) 4 20 below the adjustable setpoint. The Full Scale Volt Drop 3.4V 3.5V At 20mA Input switched output can be connected to any Relay Current 130mA Rated at 110Vac potential within 1kV of the transmitter Output Resistance On 24 110Vac Relay Type supply, while transients of 2.5kV can be Trip Point Accuracy 0.25% withstood. Trip Point Drift 100ppm/C The relay is designed to switch AC or DC. Temp Coefficient 100ppm/C The trip amplifier is typically used to Relay Time Response 10ms activate a warning or control system Operating Ambient 0C 55C override when a sensor output goes above Relative Humidity 0% 90% see note or below a pre-set limit. Alternatively, the Isolation Voltage 1kV unit can be used for simple on/off control, Surge Voltage 2.5kV for 50S Transient of 10kV/S having a built in switching hysteresis. Notes Setpoint is adjusted by 20 turn potentiometers on the front panel. The device is housed in an ultra-compact Setpoint can be checked by measuring the 0.4 to 2V (2-20mA) voltage on the front panel High or Low Alarm is selectable using internal link. DIN rail mounted enclosure, only 18mm Closed output contact is indicated by a red LED on the front panel wide.
