24 Volt (supplied)
V+
Positive side of 24 volt power supply. Used to power
external devices.
Positive side of 24V external device, i.e., flow switch, moisture
sensor, alternator, etc. Need to complete the circuit with V-. See
Figures 15 and 17.
40mA maximum output
V-
Negative side of 24 volt power supply. Used to power
external devices.
Typically to I1-, I2-, or O1+. Used with a flow switch, moisture
sensor, alternator, etc. Need to complete the circuit with V+. See
Figures 15 and 17.
40mA maximum output
I1+
Positive connection of Digital Input 1. Connect when
using an external device to control Intellidrive.
From an external device i.e., flow switch, moisture sensor,
alternator, etc. Requires complete circuit connection with I1-.
See Figures 15 and 16.
Accepts 24VDC and up to
230VAC
I1-
Negative connection of Digital Input 1. Connect when
using an external device to control Intellidrive.
Can be from V- or from the negative side of an external power
supply. Requires complete circuit connection with I1+. See
Figures 15 and 16.
Accepts 24VDC and up to
230VAC
I2+
Positive connection of Digital Input 2. Connect when
using an external device to control Intellidrive.
From an external device, i.e., flow switch, moisture sensor,
alternator, etc. Requires complete circuit connection with I2-.
See Figures 15 and 16.
Accepts 24VDC and up to
230VAC
I2-
Negative connection of Digital Input 2. Connect when
using an external device to control Intellidrive.
Can be from V- or from the negative side of an external power
supply. Requires complete circuit connection with I2+. See
Figures 15 and 16.
Accepts 24VDC and up to
230VAC
