Inputs and Outputs
Each controller has four digital inputs (DI), six or eight
digital outputs (DO), three analog outputs (AO), and six
universal input (UI) circuits.
The PVB6436AS has only 6 digital Triac outputs available,
the PVB6438NS and PUB6438S each have eight digital
Triac outputs available, and PUB6438SR has eight digital
relay outputs available.
Digital Input (DI) Circuits
Voltage Rating: 0 to 30 Vdc open circuit
Input Type: Dry contact to detect open and closed circuit
Operating Range:
Open circuit = False; Closed circuit = True
Resistance:
Open circuit > 3,000 Ohms; Closed circuit < 500 Ohms
Digital Triac Output (DO) Circuits
Voltage Rating: 20 to 30 Vac @ 50-60Hz
Current Rating: 25 mA to 500 mA continuous, 800 mA
(AC rms) for 60 milliseconds
Digital Relay Output (DO) Circuits
(PUB6438SR only)
Voltage Rating: 20 to 30 Vac @ 50-60Hz
Current Rating: 0 mA to 1 A continuous, 3.5 A inrush
(AC rms) for 100 milliseconds
Analog Output (AO) Circuits
Analog outputs are individually configurable for current or
voltage.
ANALOG CURRENT OUTPUTS:
Current Output Range: 4.0 to 20.0 mA
Output Load Resistance: 550 Ohms maximum
ANALOG VOLTAGE OUTPUTS:
Voltage Output Range: 0.0 to 10.0 Vdc
Maximum Output Current: 10.0 mA
Analog outputs may be configured as digital outputs and
operate as follows:
– False (0%) produces 0 Vdc, (0 mA)
– True (100%) produces the maximum 11 Vdc, (22 mA)
