HMI140 / HMI145 / HMI150 Interface module for Bender charge controllers Figure depending on the variant

Interface module for Bender charge controllers Device features (depending on the • Power supply via USB or external DC power supply • RFID reader for authorization of the charging process • 11 full-colour RGB LEDs for static or animated visualization of different operating states • Buzzer for acoustic signalling of states or for confirming user input • Relay output (single-pole changeover contact) • Integrated WiFi module (front-end module) • Controllable full-colour RGB LED outputs • Digital control input • Ambient light sensor • Temperature sensor The Human Machine Interface module, hereafter...

Dimension diagram Voltage supply connection Voltage supply connection, 5 V from the charge controller via USB Connection of additional DC supply (e.g. charge controller, external power supply unit)* LEDs can be connected without series resistors (constant current control) Always required for controlling the unit Required when using • USB host output (type A) • Relay switching output Terminal C, red marked (see chapter "Connection assignment, terminals C and D", page 4)

Connection assignment, terminals C and D Examples for connecting the external RGB LED outputs Example 1: LED with shared cathode Terminal C: Phoenix Contact DMC 1.5/ 4-G1-3.5 P26THR R44 (2x4-pole) Designation Example 2: Two LEDs per channel with shared anode Terminal D: Phoenix Contact DMC 1.5/ 4-G1-3.5 P26THR R44 (2x4-pole) Designation
