Mechanical/Electrical Description 2-3
2.2.3 Relay Outputs
Three relay outputs can be turned on and off as a result of data comparisons in the
drive. Refer to table 3.9 and chapter 4 for the related parameters and programming
information.
Each output has an adjustable time delay that can be programmed as an on-delay or
an off-delay as shown in table 2.2. All contacts are rated at 2A, 24VDC or 250VA,
120 VAC.
2.2.4 Analog Input
The analog input is based on a 10-bit analog-to-digital (A/D) converter and is
jumper-selected between 0 to 10 volts or 0 to 20 mA (refer to figure 2.1 for the jumper
location). Separate connection terminals are provided for voltage input and current
input. The inputs are overvoltage-protected. Offset and gain are computed by
software.
2.2.5 Analog Outputs
There are three analog output channels configured, as shown in table 2.3. Refer to
figure 2.1 for the jumper location. The outputs are short circuit-protected. The output
value is modulated over four 1ms scans to provide 10-bit data resolution.
2.2.6 Frequency Input
The frequency input operates from 0 to 200kHz, 15VDC. The input is single-ended
and uses the same common as the analog input.
