2.5 CONTROL AND ALARM OUTPUTS
32 Individually selectable control outputs:
Digital Outputs: Time proportioning, On/Off, Alarms: voltage
output: 5VDC at 6ma maximum for solid state or
other relays.
Analog: voltage or current: selectable (4 to 20ma, or 0 to 5
volts).
2.6 DIGITAL INPUT OR OUTPUT
24 DigitalOutputs:
TTL Level: true= < 0.4v @ 6ma false = > 3.9v
@ 6ma
16 Digital Inputs: TTL Level:
2.7 ANALOG OUTPUTS
Types:
0 to 5Vdc at 5ma max.
4-20ma at 8Vdc max [maximum loop impedance
400 ohms].
Both are available at the output terminals of each
output. Either can be used -- no jumpers are
required. DO NOT USE BOTH ON SAME
OUTPUT.
Accuracy: +3%
Resolution: 0.4%
