Input range: DC0V to 10V 0mA to 20mA, determined by parameter P437 determines 2. Input impedance: 22kΩ for voltage input, 500Ω for current input 500Ω AI2 GND Analog input terminal 2 1. Input range: DC0V to 10V 0mA to 20mA, determined by parameter P4 to 37 determines 2. Input impedance: 22kΩ for voltage input, 500Ω for current input 500Ω AO1 GND Analog output terminal 1 Output voltage range: 0V to 10V Output current range: 0mA- to 20mA, 4 to 20mA (P5 to 23 selectable) AO2 GND Analog output terminal 2 Output voltage range: 0V to 10V No current output function J1 jumper cap on isolated main control board to AO2 position, non isolated main control board does not have this function. This function is not available on non isolated main control boards. Digital inputs X1 COM Digital input 1 HD1 (X5), in addition to the features of X1 to X4, can also be used as a high speed pulse input channel. Maximum input frequency: 50kHz 1. Input impedance: 1kΩ 2. Voltage range at level input: 5V to 30V X2 COM Digital input 2 X3 COM Digital input 3 X4 COM Digital input 4 HDI COM(X5 terminal) Digital input 5 High speed pulse input terminals A+B- RS485 communication A+ is the positive input for the differential signal of 485 communication, B- is the negative input for the differential signal Digital Outputs Y1 COM Open collector output When used as open collector output terminal (J1 jumper cap to AO2 position on 90 isolated main control board) HDO COM High speed pulse output Subject to function code P5 00 HDO terminal output mode selection when used as high speed pulse output up to 50kHz, when used as open collector output, same specifications as Y1.
