Binary inputs units IM3-20B, IM3-40B

• TO CONNECT UP TO 2/4 DEVICES WITH POTENTIAL-FREE CONTACT (PIR, BUTTON, ETC.), 1 X THERMO INPUT TZ/TC, OUTPUT FOR POWERING DETECTORS 12 V DC/75 MA, MOUNTING INTO AN INSTALLATION BOX

BINARY INPUT UNITS IM3-20B, IM3-40B AND IM3-80B ARE USED FOR CONNECTION OF 2, 4 OR 8 DEVICES WITH POTENTIAL-LESS CONTACTS (SWITCHES, BUTTONS, SWITCHES OF OTHER DESIGN, PIR SENSORS, FIRE AND GAS DETECTORS, ETC.)

PART OF THE INPUTS CAN BE USED AS A BALANCED FOR ALARM DETECTORS:

• IM3-20B – INPUTS IN1, IN2
• IM3-40B – INPUTS IN1, IN2
• M3-80B – INPUTS IN1 – IN5
• CONTACTS OF EXTERNAL DEVICES CONNECTED TO THE INPUTS OF THE UNIT CAN BE NO OR NC – INPUT PARAMETERS ARE CONFIGURED IN THE SOFTWARE IDM.
• THE UNITS GENERATE A SUPPLY VOLTAGE OF 12V DC/75 MA FOR POWERING EXTERNAL INTRUSION DETECTORS, SO THEY CAN POWER PIR DETECTORS, FIRE AND GAS DETECTORS.
• ACTIVE USE 12V DC OUTPUT FOR POWERING DETECTORS INCREASES THE NOMINAL CONSUMPTION OF UNITS FROM BUS (SEE TECHNICAL DATA).
• THE UNITS CAN BE USED FOR COUNTING PULSES OF ENERGY METERS WITH PULSE OUTPUT.
• THE UNITS ARE EQUIPPED WITH A TEMPERATURE INPUT FOR CONNECTING AN EXTERNAL TWO-WIRE TEMPERATURE SENSOR TC/TZ (SEE ACCESSORIES).
• IM3-20B, IM3-40B, IM3-80B IN CASE TYPE B ARE DESIGNED FOR MOUNTING INTO A WIRING BOX.
